Hi, I am using U boot for my project. I need to configure the console while booting by prompting the user from target board LCD and Keypad. So please let me know which file of the U-boot I have to modify to achieve this.

[U-Boot] [PATCH v2 0/4] DFU initial implementation
by Andrzej Pietrasiewicz 24 Apr '12

24 Apr '12

Dear All, This is a quick-and-dirty proof-of-concept for splitting the dfu into core dfu gadget, generic parts of dfu backend, dfu command and target-specific implementation for Goni. This patch definitely needs some coding style cleanups. Also, the place for storing generic parts of dfu was chosen somewhat arbitrary and can be changed if a better alternative is found. The original idea of the flash_entity was to equip it with a void * to a context structure, which is not interpreted by the dfu gadget but passed to the dfu backend and understood there. I am still hesitating if flash_entity_ctx is generic enough to be generalized, as of now I assumed it is. If it wasn't then less common code could be extracted. @Stefan: you need the first 3 patches from this series, and then you need to implement your own target-specific parts. In fact, all is expected from the target, is to provide board_dfu_init/cleanup pair and call register_flash_entities.

[U-Boot] [PATCH v4] Add 'patman' patch generation, checking and submission script
by Simon Glass 21 Apr '12

21 Apr '12

What is this? ============= This tool is a Python script which: - Creates patch directly from your branch - Cleans them up by removing unwanted tags - Inserts a cover letter with change lists - Runs the patches through checkpatch.pl and its own checks - Optionally emails them out to selected people It is intended to automate patch creation and make it a less error-prone process. It is useful for U-Boot and Linux work so far, since it uses the checkpatch.pl script. It is configured almost entirely by tags it finds in your commits. This means that you can work on a number of different branches at once, and keep the settings with each branch rather than having to git format-patch, git send-email, etc. with the correct parameters each time. So for example if you put: in one of your commits, the series will be sent there. See the README file for full details. END Signed-off-by: Simon Glass <sjg(a)chromium.org> --- Changes in v2: - Fix up use of Color in series.py (avoid runtime error) Changes in v3: - Add a few more tests (but still very incomplete) - Add option to display the README - Change cc-list tmpfile name to start with patman - Expand the README to include info about suggested workflow - Find checkpatch.pl in U-Boot tree - Fix generation of cc list to match patch names correctly - Support git's alias file if found in config sendemail.aliasesfile - Support recursive aliases - Tidy up gitutil and settings to separate code better - Use -M with git format-patch to so that file moves are tracked - Use @{upstream} instead of the previous mess (thanks Anton Staff) Changes in v4: - Add --no-tags options to not Cc maintainers on tags - Add per-commit change log (automatically puts them all in cover letter) - Allow multiple Signed-off-by tags - Append valid tags to the patch - Make aliases additive so you can add more to an alias later - Sort change lists tools/patman/.gitignore | 1 + tools/patman/README | 408 +++++++++++++++++++++++++++++++++++++++ tools/patman/checkpatch.py | 161 ++++++++++++++++ tools/patman/command.py | 72 +++++++ tools/patman/commit.py | 87 +++++++++ tools/patman/gitutil.py | 372 ++++++++++++++++++++++++++++++++++++ tools/patman/patchstream.py | 444 +++++++++++++++++++++++++++++++++++++++++++ tools/patman/patman | 1 + tools/patman/patman.py | 153 +++++++++++++++ tools/patman/series.py | 238 +++++++++++++++++++++++ tools/patman/settings.py | 81 ++++++++ tools/patman/terminal.py | 86 +++++++++ tools/patman/test.py | 250 ++++++++++++++++++++++++ 13 files changed, 2354 insertions(+), 0 deletions(-) create mode 100644 tools/patman/.gitignore create mode 100644 tools/patman/README create mode 100644 tools/patman/checkpatch.py create mode 100644 tools/patman/command.py create mode 100644 tools/patman/commit.py create mode 100644 tools/patman/gitutil.py create mode 100644 tools/patman/patchstream.py create mode 120000 tools/patman/patman create mode 100755 tools/patman/patman.py create mode 100644 tools/patman/series.py create mode 100644 tools/patman/settings.py create mode 100644 tools/patman/terminal.py create mode 100644 tools/patman/test.py diff --git a/tools/patman/.gitignore b/tools/patman/.gitignore new file mode 100644 index 0000000..0d20b64 --- /dev/null +++ b/tools/patman/.gitignore @@ -0,0 +1 @@ +*.pyc diff --git a/tools/patman/README b/tools/patman/README new file mode 100644 index 0000000..ee38afc --- /dev/null +++ b/tools/patman/README @@ -0,0 +1,408 @@ +# Copyright (c) 2011 The Chromium OS Authors. +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

So for example if you put: + +Series-to: fred.blogs(a)napier.co.nz + +in one of your commits, the series will be sent there. + + +How to use this tool +==================== + +This tool requires a certain way of working: + +- Maintain a number of branches, one for each patch series you are +working on +- Add tags into the commits within each branch to indicate where the +series should be sent, cover letter, version, etc. Most of these are +normally in the top commit so it is easy to change them with 'git +commit --amend' +- Each branch tracks the upstream branch, so that this script can +automatically determine the number of commits in it (optional) +- Check out a branch, and run this script to create and send out your +patches. Weeks later, change the patches and repeat, knowing that you +will get a consistent result each time. + + +How to configure it +=================== + +For most cases patman will locate and use the file 'doc/git-mailrc' in +your U-Boot directory. This contains most of the aliases you will need. + +To add your own, create a file ~/.config/patman directory like this: + +>>>> +# patman alias file + +[alias] +me: Simon Glass <sjg(a)chromium.org> + +u-boot: U-Boot Mailing List <u-boot(a)lists.denx.de> +wolfgang: Wolfgang Denk <wd(a)denx.de> +others: Mike Frysinger <vapier(a)gentoo.org>, Fred Bloggs <f.bloggs(a)napier.net> + +<<<< + +Aliases are recursive. + +The checkpatch.pl in the U-Boot tools/ subdirectory will be located and +used. Failing that you can put it into your path or ~/bin/checkpatch.pl + + +How to run it +============= + +First do a dry run: + +$ ./tools/scripts/patman/patman -n + +If it can't detect the upstream branch, try telling it how many patches +there are in your series: + +$ ./tools/scripts/patman/patman -n -c5 + +This will create patch files in your current directory and tell you who +it is thinking of sending them to. Take a look at the patch files. + +$ ./tools/scripts/patman/patman -n -c5 -s1 + +Similar to the above, but skip the first commit and take the next 5. This +is useful if your top commit is for setting up testing. + + +How to add tags +=============== + +To make this script useful you must add tags like the following into any +commit. Most can only appear once in the whole series. + +Series-to: email / alias + Email address / alias to send patch series to (you can add this + multiple times) + +Series-cc: email / alias, ... + Email address / alias to Cc patch series to (you can add this + multiple times) + +Series-version: n + Sets the version number of this patch series + +Series-prefix: prefix + Sets the subject prefix. Normally empty but it can be RFC for + RFC patches, or RESEND if you are being ignored. + +Cover-letter: +This is the patch set title +blah blah +more blah blah +END + Sets the cover letter contents for the series. The first line + will become the subject of the cover letter + +Series-notes: +blah blah +blah blah +more blah blah +END + Sets some notes for the patch series, which you don't want in + the commit messages, but do want to send, The notes are joined + together and put after the cover letter. Can appear multiple + times. + + Signed-off-by: Their Name <email> + A sign-off is added automatically to your patches (this is + probably a bug). If you put this tag in your patches, it will + override the default signoff that patman automatically adds. + + Tested-by: Their Name <email> + Acked-by: Their Name <email> + These indicate that someone has acked or tested your patch. + When you get this reply on the mailing list, you can add this + tag to the relevant commit and the script will include it when + you send out the next version. If 'Tested-by:' is set to + yourself, it will be removed. No one will believe you. + +Series-changes: n +- Guinea pig moved into its cage +- Other changes ending with a blank line +<blank line> + This can appear in any commit. It lists the changes for a + particular version n of that commit. The change list is + created based on this information. Each commit gets its own + change list and also the whole thing is repeated in the cover + letter (where duplicate change lines are merged). + + By adding your change lists into your commits it is easier to + keep track of what happened. When you amend a commit, remember + to update the log there and then, knowing that the script will + do the rest. + +Cc: Their Name <email> + This copies a single patch to another email address. + +Various other tags are silently removed, like these Chrome OS and +Gerrit tags: + +BUG=... +TEST=... +Change-Id: +Review URL: +Reviewed-on: +Reviewed-by: + + +Exercise for the reader: Try adding some tags to one of your current +patch series and see how the patches turn out. + + +Where Patches Are Sent +====================== + +Once the patches are created, patman sends them using gti send-email. The +whole series is sent to the recipients in Series-to: and Series-cc. +You can Cc individual patches to other people with the Cc: tag. Tags in the +subject are also picked up to Cc patches. For example, a commit like this: + +>>>> +commit 10212537b85ff9b6e09c82045127522c0f0db981 +Author: Mike Frysinger <vapier(a)gentoo.org> +Date: Mon Nov 7 23:18:44 2011 -0500 + + x86: arm: add a git mailrc file for maintainers + + This should make sending out e-mails to the right people easier. + + Cc: sandbox, mikef, ag + Cc: afleming +<<<< + +will create a patch which is copied to x86, arm, sandbox, mikef, ag and +afleming. + + +Example Work Flow +================= + +The basic workflow is to create your commits, add some tags to the top +commit, and type 'patman' to check and send them. + +Here is an example workflow for a series of 4 patches. Let's say you have +these rather contrived patches in the following order in branch us-cmd in +your tree where 'us' means your upstreaming activity (newest to oldest as +output by git log --oneline): + + 7c7909c wip + 89234f5 Don't include standard parser if hush is used + 8d640a7 mmc: sparc: Stop using builtin_run_command() + 0c859a9 Rename run_command2() to run_command() + a74443f sandbox: Rename run_command() to builtin_run_command() + +The first patch is some test things that enable your code to be compiled, +but that you don't want to submit because there is an existing patch for it +on the list. So you can tell patman to create and check some patches +(skipping the first patch) with: + + patman -s1 -n + +If you want to do all of them including the work-in-progress one, then +(if you are tracking an upstream branch): + + patman -n + +Let's say that patman reports an error in the second patch. Then: + + git rebase -i HEAD~6 + <change 'pick' to 'edit' in 89234f5> + <use editor to make code changes> + git add -u + git rebase --continue + +Now you have an updated patch series. To check it: + + patman -s1 -n + +Let's say it is now clean and you want to send it. Now you need to set up +the destination. So amend the top commit with: + + git commit --amend + +Use your editor to add some tags, so that the whole commit message is: + + The current run_command() is really only one of the options, with + hush providing the other. It really shouldn't be called directly + in case the hush parser is bring used, so rename this function to + better explain its purpose. + + Series-to: u-boot + Series-cc: bfin, marex + Series-prefix: RFC + Cover-letter: + Unified command execution in one place + + At present two parsers have similar code to execute commands. Also + cmd_usage() is called all over the place. This series adds a single + function which processes commands called cmd_process(). + END + + Change-Id: Ica71a14c1f0ecb5650f771a32fecb8d2eb9d8a17 + + +You want this to be an RFC and Cc the whole series to the bfin alias and +to Marek. Two of the patches have tags (those are the bits at the front of +the subject that say mmc: sparc: and sandbox:), so 8d640a7 will be Cc'd to +mmc and sparc, and the last one to sandbox. + +Now to send the patches, take off the -n flag: + + patman -s1 + +The patches will be created, shown in your editor, and then sent along with +the cover letter. Note that patman's tags are automatically removed so that +people on the list don't see your secret info. + +Of course patches often attract comments and you need to make some updates. +Let's say one person sent comments and you get an Acked-by: on one patch. +Also, the patch on the list that you were waiting for has been merged, +so you can drop your wip commit. So you resync with upstream: + + git fetch origin (or whatever upstream is called) + git rebase origin/master + +and use git rebase -i to edit the commits, dropping the wip one. You add +the ack tag to one commit: + + Acked-by: Heiko Schocher <hs(a)denx.de> + +update the Series-cc: in the top commit: + + Series-cc: bfin, marex, Heiko Schocher <hs(a)denx.de> + +and remove the Series-prefix: tag since it it isn't an RFC any more. The +series is now version two, so the series info in the top commit looks like +this: + + Series-to: u-boot + Series-cc: bfin, marex, Heiko Schocher <hs(a)denx.de> + Series-version: 2 + Cover-letter: + ... + +Finally, you need to add a change log to the two commits you changed. You +add change logs to each individual commit where the changes happened, like +this: + + Series-changes: 2 + - Updated the command decoder to reduce code size + - Wound the torque propounder up a little more + +(note the blank line at the end of the list) + +When you run patman it will collect all the change logs from the different +commits and combine them into the cover letter, if you have one. So finally +you have a new series of commits: + + faeb973 Don't include standard parser if hush is used + 1b2f2fe mmc: sparc: Stop using builtin_run_command() + cfbe330 Rename run_command2() to run_command() + 0682677 sandbox: Rename run_command() to builtin_run_command() + +so to send them: + + patman + +and it will create and send the version 2 series. + +General points: + +1. When you change back to the us-cmd branch days or weeks later all your +information is still there, safely stored in the commits. You don't need +to remember what version you are up to, who you sent the last lot of patches +to, or anything about the change logs. + +2. If you put tags in the subject, patman will Cc the maintainers +automatically in many cases. + +3. If you want to keep the commits from each series you sent so that you can +compare change and see what you did, you can either create a new branch for +each version, or just tag the branch before you start changing it: + + git tag sent/us-cmd-rfc + ...later... + git tag sent/us-cmd-v2 + +4. If you want to modify the patches a little before sending, you can do +this in your editor, but be careful! + +5. If you want to run git send-email yourself, use the -n flag which will +print out the command line patman would have used. + +6. It is a good idea to add the change log info as you change the commit, +not later when you can't remember which patch you changed. You can always +go back and change or remove logs from commits. + + +Other thoughts +============== + +This script has been split into sensible files but still needs work. +Most of these are indicated by a TODO in the code. + +It would be nice if this could handle the In-reply-to side of things. + +The tests are incomplete, as is customary. Use the -t flag to run them, +and make sure you are in the tools/scripts/patman directory first: + + $ cd /path/to/u-boot + $ cd tools/scripts/patman + $ patman -t + +Error handling doesn't always produce friendly error messages - e.g. +putting an incorrect tag in a commit may provide a confusing message. + +There might be a few other features not mentioned in this README. They +might be bugs. In particular, tags are case sensitive which is probably +a bad thing. + + +Simon Glass <sjg(a)chromium.org> +v1, v2, 19-Oct-11 +revised v3 24-Nov-11 diff --git a/tools/patman/checkpatch.py b/tools/patman/checkpatch.py new file mode 100644 index 0000000..a234277 --- /dev/null +++ b/tools/patman/checkpatch.py @@ -0,0 +1,161 @@ +# Copyright (c) 2011 The Chromium OS Authors. +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[U-Boot-Users] Ethernet loopback command
by Thomas Schäfer 17 Apr '12

17 Apr '12

Hi, The patch attached provides a command called 'ethloop' which allows to perform loopback testing on the current eth device. To achieve this, a new ethernet packet type (PROT_TEST, 0x0808, AFAIK this is not used otherwise) is introduced in net/net.c. The patch is against SF CVS from 20050307. The functions EthLoopStart, EthLoopSend and EthLoopHandler generate a simple ethernet frame with NetOurEther as destination address and packet type PROT_TEST. The looped back package is compared with the original one and a message is displayed. It is necessary to set the ethernet line into loopback mode either by programming the PHY or using a loopback plug. I've tested this on our PPC405 custom board, but it should also work on all other systems because packet generation is independent of the underlying ethernet hardware. Example usage: => mii w 0 0 7100 <-- sets PHY into loopback mode => ethloop Using ppc_405x_eth0 device Got ethernet loopback frame, len=64 loopback test successfully completed => mii w 0 0 8000 <-- PHY reset after test is completed Maybe this is also useful for others..

This series adds NAND flash support to Tegra and enables it on Seaboard. Included here is a proposed device tree binding which I'm sure will stretch some eyes. The binding includes information about the NAND controller as well as the connected NAND device. The Seaboard has a Hynix HY27UF4G2B. The driver supports ECC-based access and uses DMA and NAND acceleration features of the Tegra SOC to provide access at reasonable speed.

Hi I am getting DTC when compiling dts file with CONFIG_OF_CONTROL. The message says that it cannot find skeleton.dtsi though its placed in the same directory as the dts file. I notice that if i remove this line from the dts Makefile, the error disappears $(DT_BIN): $(TOPDIR)/board/$(VENDOR)/dts/$(DEVICE_TREE).dts - cat $< | $(CPP) -P $(DTS_CPPFLAGS) - >$@.tmp - $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $@.tmp - rm $@.tmp + $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $< Has anyone faced this issue? Thanks Hanumant
