[U-Boot] [PATCH v9 09/31] Introduce generic pre-relocation board_f.c

[U-Boot] [PATCH v9 09/31] Introduce generic pre-relocation board_f.c

[Simon Glass]

This file handles common pre-relocation init for boards which use
the generic framework.

It starts up the console, DRAM, performs relocation and then jumps
to post-relocation init.

Signed-off-by: Simon Glass <sjg@chromium.org>
---
Changes in v9:
- Rebase x86 global_data patch on top of mainline

Changes in v8: None
Changes in v7: None
Changes in v6:
- Tidy up stack reservation code to separate out ARM
- Fix up ordering of dram init (specifically to get ARM SPL boards to boot)
- Add debug() to show RAM top
- Adjust the way the top of memory is calculated

Changes in v5:
- Add fdtdec header file to board_f.c
- Remove setup_global_data_ptr()
- Tidy up stack init
- Put global data on stack in board_init_f()
- Add fdt relocation
- Remove fdt relocation field from x86 arch_global_data
- Deal with change of board_init_f() semantics on ARM
- Save boot_flags in global_data in board_init_f()
- Add print_cpuinfo() prototype to include/common.h

Changes in v4:
- Use asm/sections.h instead of asm-generic/sections.h

Changes in v3:
- Cast away the volatile on gd for memcpy()

Changes in v2: None

I did some testing on Power Architecture systems - to be precise:

CPU		Board
--------------------------
MPC860T		TQM860L
MPC5200		TQM5200S
PPC405EX	Kilauea
PPC440EP	Yosemite
PPC440EX	Sequoia
PPC440SPe	Katmai
PPC460EX	Canyonlands

On all boards I verified at least environment access (printenv,
saveenv) and network operation (TFTP download); where available also
PCI.  Everything appears to work fine, no problems noted.

A well done job, thanks a lot!

For the whole series:

OK, I've taken http://patchwork.ozlabs.org/bundle/sjg/us-board/ but with
http://patchwork.ozlabs.org/patch/228080/ for 2/31 and applied this to
u-boot/master now, thanks again!

Thanks for your comments which are much appreciated. There is still work to
do, in cleaning up the implementation to reduce the differences between
arch code (e.g. all the #ifdefs in board_f/r.c). But this is a great first
step and I am pleased to get this in.

But I wonder if this is trying to tell me to stop these tricky refactors :-)

I have created a branch on x86 for this as follows, in case this helps. But
I believe Wolfgang is hoping to look at getting it running on PowerPC, so
it might be worth holding off for more news.

I forgot to mention that if anyone wants to try this out on their
board, the tree is at

http://git.denx.de/u-boot-x86.git

branch 'us-board-v11'

I tested the whole series on avr32. The minor changes there do not break
runtime behaviour, therefore

Tested-by: Andreas Bie?mann <andreas.biessmann@googlemail.com>

Will this series be applied for upcomming release? I'm asking cause of

http://patchwork.ozlabs.org/patch/225225/

vs

http://patchwork.ozlabs.org/patch/220413/

Best regards

Seeing as there's Wolfgang's tested/ack yes, this is quite likely to go
in.  Need to review it all again myself to be sure.  Simon, can you
please make a patchwork bundle out of it as well so I can be sure all of
the patches are updated right (ie we have the old ones cleared out
and the new ones assigned to me).  Thanks!

I found that one patch (2/31) needed a rev due to a recent change. I
resent this so it should hit patchwork soon.

I did create a bundle but things were in the wrong order, so I will
try again when that happens.

In the meantime there is a tree at u-boot-x86.git branch us-board-v11,
and I can do a pull request if you like.

Regards,
Simon

Please see the patchwork bundle here:

http://patchwork.ozlabs.org/bundle/sjg/us-board/

I had to rebase one of the patches and resend to the mailing this. But
I just tried this bundle and it applied cleanly to master for me.
