[U-Boot] [PATCH 00/29] Rework MPC512x Support
The following patch series includes a heavy rework of the existing code for MPC512x processors. The changes include especially:
- move common files from mpc5121ads (so far ads5121) board to common directory so they can be reused by other boards based on the same CPU - rename "ads5121" into "freescale/mpc5121ads" so thesame board name as in Linux is used, and the vendor directory is correct - rework the whole MPC512x related code to use I/O acessors (i. e. in_*() and out_*() functions) instead of deprecated pointer accesses - Don't #define register offsets, but use the offset from the respective C structs instead [1] - remove include/mpc512x.h to avoid duplication of the same information in include/asm-ppc/immap_512x.h - add support for the ARIA board, a MPC5121e based COM Express module
[1] Note: It was not possible to get completely rid of #define'd register offsets yet, as some are used in cpu/mpc512x/start.S, and in assembly the available options are limited. In Linux, the required header files with the respective #define's are auto-generated from the C struct definitions. We intend to do the same, but this needs co-ordinations across architectures - for example, Blackfin already uses such an approach. For now, we created cpu/mpc512x/asm-offsets.h; this file will be removed again as soon as auto-generation works.
Note: It might seem a good idea to squash related patches (like all I/O accessors patches into one, and all mpc512x.h removal patches into another one) to reduce the number of commits. I decided against doing this, as the amount of changes carries the risk that, inspite of pretty careful testing, some errors have not been discovered yet. The current one-step-at-a-time approach is more git-bisect friendly.
Patches are agains v2009.06-rc1; they have been tested on the "mpc5121ads" and the "aria" boards.

We will soon see several new MPC521x based boards added. This patch moves files that are not board specific to a common directory so they can be shared by all such ports.

Sorry - yes, of course.
Best regards,
Wolfgang Denk
- add GPIO module description - add Address Latch Timing Register description - add IO Control Memory Map - add FEC Memory Map
Also change board/freescale/mpc5121ads/mpc5121ads.c and cpu/mpc512x/iopin.c as needed.

phys_size_t initdram (int board_type) { return fixed_sdram (); }
And I noticed that are mixing the coding style's in this file (space before "(" of functions): fixed_sdram () vs. out_be(...). Better it would be consistent.

Dear Stefan,
In message 200905110917.21667.sr@denx.de you wrote:
+phys_size_t initdram (int board_type) +{
- u32 msize = 0;
- msize = fixed_sdram ();
- return msize;
+}
Or just:
phys_size_t initdram (int board_type) { return fixed_sdram (); }
Right, will change.
And I noticed that are mixing the coding style's in this file (space before "(" of functions): fixed_sdram () vs. out_be(...). Better it would be consistent.
Indeed. Will change, too. Thanks for pointing out.
[I'll continue to collect review comments for a few more days and then post patch series V2; in the meantime, the current, updated code, rebased against "next", is available in the "aria" branch of the u-boot-testing repository.]
Best regards,
Wolfgang Denk

Move needed definitions (register descriptions etc.) from include/mpc512x.h into include/asm-ppc/immap_512x.h.
All the rest of include/mpc512x.h are register offset definitions which can be eliminated by proper use of C structures - of course in combination with replacing pointer accesses by I/O accessor calls.
There are only a few register offsets remaining that are needed in cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h which is intended as a temporary workaround only. In a later patch this file will be removed, too, and then auto-generated from the respective C structs.

No it is fine for me, I just sequentially read the EMails, so I saw the patch, which uses the in/out accessors later ;-)
Hmm... I think the complete patchseries go through the mpc5xxx custodian, so I only have to ACK this patches, right?

Yes, I know - for reviewing the stuff the split into small steps is not optimal. BUt I found it very useful for debugging.

Indeed.

Wolfgang,
I think it is time to hand over 5xxx maintainership to you.
I did go over these patches they look good to me.

- rename "ads5121" into "freescale/mpc5121ads" so thesame board name
as in Linux is used, and the vendor directory is correct
- rework the whole MPC512x related code to use I/O acessors (i. e.
in_*() and out_*() functions) instead of deprecated pointer accesses
- Don't #define register offsets, but use the offset from the
respective C structs instead [1]
- remove include/mpc512x.h to avoid duplication of the same
information in include/asm-ppc/immap_512x.h
- add support for the ARIA board, a MPC5121e based COM Express module
[1] Note: It was not possible to get completely rid of #define'd register offsets yet, as some are used in cpu/mpc512x/start.S, and in assembly the available options are limited. In Linux, the required header files with the respective #define's are auto-generated from the C struct definitions. We intend to do the same, but this needs co-ordinations across architectures - for example, Blackfin already uses such an approach. For now, we created cpu/mpc512x/asm-offsets.h; this file will be removed again as soon as auto-generation works.
Note: It might seem a good idea to squash related patches (like all I/O accessors patches into one, and all mpc512x.h removal patches into another one) to reduce the number of commits. I decided against doing this, as the amount of changes carries the risk that, inspite of pretty careful testing, some errors have not been discovered yet. The current one-step-at-a-time approach is more git-bisect friendly.

there seem to be recurring themes among these patches - this patchseries would be better grouped into theme based content instead of on a file by file basis. Eg., Removal of mpc512x.h shouldn't need 10 "prepare to remove" patches - it should be a single patch that removes all #include references, plus the file removal itself.

You are right, there should be just a single patch. But that patch would be big, and if it later turns out that I missed something during my testing, it will be a nightmare to debug.
Been there before. I already had such a patch stack, which I then collapsed into a small number of handy commits. Until it turned out that there was a nasty bug somewhere. And there is no "unsquash" option to "git-besect -i" yet ;-) In the end, I had to restore the previous version from backup tape.
I really thought about this, and I came to the conclusion that it's better to keep the commits separate, step by step.
Best regards,
Wolfgang Denk

? wouldn't it be approximately the size of the file plus ten single-line hunks removing the #include lines in the rest of the code, i.e, a tad larger than patch 29/29? Plus it would significantly reduce the intimidating denominator number of this patchseries (making it approx. 10 commits less, and that's only on the subject of the removal of this mpc512x file).

I'm not going to tell you how to do your development, but you don't have to expose artefacts of your personal debugging cycles to reviewers nor unnecessarily clutter git bisect with unnecessary commits.

It's not exactly that trivial, unfortunately.

Patches are against current "next" branch; each commit has been compile and run-time tested on the "mpc5121ads" board; the last patch (adding support for ARIA) has been compile and run-time tested on both the "mpc5121ads" and the "aria" boards. Run-time testing inclu- ded at least serial console, network, flash, cold boot (power-on) and warm boot (reset).
Changes since V1: only organizational, i. e. squashing related patches into one, reducing the total number of commits from 29 to 10. The resulting code is still exactly the same (except for one line difference in a comment).

great consolidating so many patches - much easier to review.
it's just that we get into the habit of using git format-patch -B -M - it greatly facilitates reviewing mass-rename patches such as this one.

Hello Mr. Denk!
Maybe a stupid question - but the manufacturer called it ADS512101 - should not that name be the right one for linux and u-boot ?
Best regards, Arno Fischer
Dear Arno Fischer,
In message MPG.247e51b45d39ae3e989680@news.gmane.org you wrote:

Maybe a stupid question - but the manufacturer called it ADS512101 - should not that name be the right one for linux and u-boot ?
It's not a stupid question. There is indeed confusion around the board name.
Situation is as follows: the manufacturer called the board "Hellrosa"; see http://www.silicontkx.com/hellrosa.htm
Freescale decided to distributre the board under the product name ADS5121 (or ADS512101).
The Linux kernel has been using the name "mpc5121ads" for the related board configuration from the beginning.
U-Boot used "ads5121" as board config name.
I don't care at all about the name of the product, i. e. the part number you have to use when ordering the board.
Also, the board configuration name is not somthing I would fight for - it's just a name after all. It does not have to be identical to the product name (which is even impossible here, as we would have to use either "hellrosa" or "ads5121", and neither of them makes everybody happy; also it's not 100% clear to me whether board/freescale/ or board/stx/ is more correct - technically or politically).
But I think it is important to use the *same* configuration name in Linux and in U-Boot - we received a lot of avoidable support calls in the past because users got confused when they had to use "ads5121" in U-Boot and "mpc5121ads" in Linux.
The purpose of the patch is to get a unique configuration name. "mpc5121" fits well with the other config names used for Freescale boards, and is identical to Linux.
If anybody wants a different board name, I don't object. But he should please care to get the config name in Linux changed first, U-Boot will then follow.
Best regards,
Wolfgang Denk
- add GPIO module description - add Address Latch Timing Register description - add IO Control Memory Map - add FEC Memory Map
Also change board/freescale/mpc5121ads/mpc5121ads.c and cpu/mpc512x/iopin.c as needed.

The whole patch series applies to the "next" branch. I just verified that it still applies cleanly (git-am) against gurrent next.
Error message above makes me think your file might have been corrupted?
If you agree with the patch, then just ACK it, and I pull everything into the 5xxx repo.

Move needed definitions (register descriptions etc.) from include/mpc512x.h into include/asm-ppc/immap_512x.h.
Instead of using a #define'd register offset, use a function that provides the PATA controller's base address.
All the rest of include/mpc512x.h are register offset definitions which can be eliminated by proper use of C structures.
There are only a few register offsets remaining that are needed in cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h which is intended as a temporary workaround only. In a later patch this file will be removed, too, and then auto-generated from the respective C structs.

Please find some mostly nitpicking comments below. (Sorry about the late review - I just stumbled over a few issue while using this port as basis for a port for an MPC5123 board from esd).
Thanks for the review.

Is this really needed?
Yes, it is - but not here. It must be added to cpu/mpc512x/Makefile, i. e. go into the "mpc512x: Move common files to share them by several boards" commit.

Please remove this empty line above.
Will do.

Curly braces can be removed. And I suggest to add an empty line here.
Will do.

Same changes applied to board/freescale/mpc5121ads/mpc5121ads.c as well.
As the modifications are mostly cosmetical only, I will push the changes directly into the u-boot-mpc5xxx repo, without posting new patches. Hope this is OK.

Dear Mr. Denk!
In article 1241898668-11903-1-git-send-email-wd@denx.de, wd@denx.de says...
The following patch series includes a heavy rework of the existing code for MPC512x processors... ... [PATCH 01/29] mpc512x: change cpu/mpc512x/Makefile to use Kconfig style [PATCH 02/29] mpc512x: Move common files to share them by several boards [PATCH 03/29] cpu/mpc512x/pci.c: minor coding style cleanup [PATCH 04/29] cpu/mpc512x/diu.c: fix warning: assignment from incompatible pointer type [PATCH 05/29] Rename ads5121 board into mpc5121ads [PATCH 06/29] MPC512x: add more hardware description to immap_512x.h [PATCH 07/29] mpc5121ads: use I/O accessors instead of pointer accesses [PATCH 08/29] MPC512x: add support for ARIA board [PATCH 09/29] cpu/mpc512x/iopin.c: convert to use I/O acessors. [PATCH 10/29] cpu/mpc512x/iopin.c: remove redundant include of <asm/immap_512x.h> [PATCH 11/29] MPC512x: prepare removal of include/mpc512x.h
I have tested the ELPIDA memory patch from Martha Marx from Feb. 20th 2009 for the ADS5121 and it worked - and even solved a DRAM init problem at power on (u-boot hangs at power on when board is warmed up). Is there a chance to include that patch too?
Best regards, Arno Fischer
Dear Arno Fischer,

As you can see in this posting: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/54983/focus=55035 I asked Martha to perform a number or relatively small and simple changes, but she never responded.
When these changes are implemented and the patches rebased against current code, they will be reconsidered.
As is, they are dropped.
Best regards,
Wolfgang Denk
