[U-Boot] [PATCH] tools: make it possible to build tools unconfigured
by Ilya Yanok 17 Oct '11

17 Oct '11

Sometimes we want to build common tools without configuring for specific target. Currently top Makefile has some support for this but it doesn't work. This patch tries to fix this. Things changed: - config.mk disable 'ld script not found error' in case if we are building tools only. - Makefile mkimage relies on autogenerated version so we need to move $(VERSION_FILE) rule out of ifeq and make tools rule depend on it. - tools/Makefile put common/env_embedded.o and envcrc.o to object list conditionally. This fixes errors during dependency generation.

[U-Boot] [PATCH v5 00/13] Add PXE support
by Jason Hobbs 17 Oct '11

17 Oct '11

This patch series adds PXE booting support to U-boot. It adds aseries of DHCP options to allow U-boot DHCP requests to be compliant with RFC 4578, and a set of commands to provide PXELINUX like behavior. The pxe commands provide a near subset of the functionality provided by the PXELINUX boot loader. This allows U-boot based systems to be controlled remotely using the same PXE based techniques that many non U-boot based servers use. As an example, support for the pxe commands is enabled for the ca9x4_ct_vxp config. Additional details for the pxe commands are available in the README.pxe file added as part of this patch series. This patch series adds support for RFC 4578 compliant DHCP request options, which enhance the ability of DHCP servers to respond differently to different clients. As an example, the last patch in this series enables support for the PXE DHCP options for the ca9x4_ct_vxp config. v5 of the patch series responds to a couple of comments from Mike Frysinger, and fixes a checkpatch simple_strtoul warning. Details are in the individual patch logs. Jason Hobbs (13): Add generic, reusable menu code common, menu: use abortboot for menu timeout common: add run_command2 for running simple or hush commands Add isblank cosmetic: remove unneeded curly braces Replace space and tab checks with isblank README: document standard image variables lib: add uuid_str_to_bin for use with bootp and PXE uuid Add pxe command net: bootp: add PXE/RFC 4578 DHCP options support Convert ca9x4_ct_vxp to standard env variables arm: ca9x4_ct_vxp: enable pxe command support arm: ca9x4_ct_vxp: enable PXE BOOTP options support README | 19 + board/hymod/env.c | 9 +- common/Makefile | 2 + common/cmd_pxe.c | 1355 ++++++++++++++++++++++++++++++++++ common/command.c | 9 +- common/hush.c | 2 +- common/main.c | 75 +- common/menu.c | 417 +++++++++++ doc/README.menu | 119 +++ doc/README.pxe | 240 ++++++ drivers/bios_emulator/x86emu/debug.c | 7 +- examples/standalone/smc911x_eeprom.c | 5 +- include/common.h | 13 + include/configs/ca9x4_ct_vxp.h | 19 +- include/hush.h | 2 +- include/linux/ctype.h | 6 + include/menu.h | 30 + lib/Makefile | 1 + lib/hashtable.c | 4 +- lib/uuid.c | 85 +++ net/bootp.c | 40 + 21 files changed, 2402 insertions(+), 57 deletions(-) create mode 100644 common/cmd_pxe.c create mode 100644 common/menu.c create mode 100644 doc/README.menu create mode 100644 doc/README.pxe create mode 100644 include/menu.h create mode 100644 lib/uuid.c

[U-Boot] [PATCH V4 7/9] DM9000:Add a byte swap macro for dm9000 io operation.
by Jason Jin 17 Oct '11

17 Oct '11

commit a45dde2293c816138e53c26eca6fd0322583f9a6 changed the dm9000 direct register access to standard IO. This should work on the ColdFire platform as there are corresponding macros for the LE devices. But the hardware settings on some ColdFire boards had swapped the byte order which make the original macros such as out_le16 cannot work. To avoid changing the common io access code on ColdFire platform, the DM9000_BYTE_SWAPPED define was added to make the dm9000 use __raw* IO access on some ColdFire boards. Signed-off-by: Jason Jin <Jason.jin(a)freescale.com> --- Changes for V2: Remove the 'volatile' in the macro. Changes for V3: Seperate the dm9000 code support and the platform code to two patches so that it can be accepted by different custodian.

[U-Boot] [PATCH] cmd_bmp: fix very long uncompressing time of gzipped bitmaps
by Anatolij Gustschin 17 Oct '11

17 Oct '11

If a compressed bitmap is located in sectors at the end of the flash and it's offset + CONFIG_SYS_VIDEO_LOGO_MAX_SIZE > 0xFFFFFFFF, the uncompressing time is very long, since processing the stream is done bytewise (and not blockwise) due to overflow in inflate_fast() while calculation and checking for enough input available. Fix available bitmap data input size for gunzip() to match the actually available data size to prevent the observed misbehaviour.

[U-Boot] [PATCH v7 0/4] Board support series for the eXMeritus HWW-1U-1A
by Kyle Moffett 16 Oct '11

16 Oct '11

This is the final respin of the eXMeritus HWW-1U-1A board support patches, rebased onto the 'next' branch of git://git.denx.de/u-boot-mpc85xx.git This code conforms to the Linux kernel coding style. It passes checkpatch with only a few false positives. I believe these 4 patches are ready to be merged. Cheers, Kyle Moffett

[U-Boot] [PATCH 1/2 v6] fdt: Add a do_fixup_by_path_string() function
by Chunhe Lan 15 Oct '11

15 Oct '11

The do_fixup_by_path_string() will set the specified node's property to the value contained in "status". It would just be an inline wrapper for do_fixup_by_path() that calls strlen on the argument.
