Incremental patch. Should be applied above its v2:
http://lists.denx.de/pipermail/u-boot/2010-April/070729.html
(Sorry for inconvenience. I will use --in-reply-to option next time)

In the patch:
- Fix for hcu4 board;
- post.h - preprocessor conditional inclusions optimization.

Combine previously submitted POST cleanup patch series
into single patch. Fix plain POST support introduced recently
for mpc812x arch.

- Revives POST for blackfin arch;
- Removes redundant code:
     arch/blackfin/lib/post.c
     board/ssv/common/post.c
     arch/powerpc/cpu/ppc4xx/commproc.c
     arch/powerpc/cpu/mpc512x/common.c
- fixes up the post_word_{load|store} usage;

Thanks for the big work.

It would have been really nice if you put the maintainers on CC (simply
include a CC: ... in the patch git-send-email does the rest) of the
boards that you change config files.  This way they knew that there was
a change which they should test and ack.

For the powerpc parts, you have my

This never worked :)  The config file has no trace of any POST, so the
change you do is pretty useless:

These changes are necessary for CONFIG_LOGBUFFER which barco board
defines that in turn requires the post_word_load and post_word_store
support.

This matters for the CONFIG_LOGBUFFER support as I explained above.

Hm.  It amazes me that CONFIG_LOGBUFFER needs a
CONFIG_SYS_POST_WORD_ADDR - I simply did not realize this.  

Ah, I see now that post.h produces these values when CONFIG_POST _or_
CONFIG_LOGBUFFER is defined.  I guess this works, but it is non-obvious
that we need post.h if no POST is used.  But still this is no reason to
NAK the patch.

Actually we do not need to include post.h if post is not used. Only
cmd_log.c includes it.
In this respect patch did not change anything.

Hi Wolfgang,

Is there any particular reason why this patch is not in the main stream yet?

Thanks,
Michael

Combine previously submitted POST cleanup patch series
into single patch. Fix plain POST support introduced recently
for mpc812x arch.

- Revives POST for blackfin arch;
- Removes redundant code:
     arch/blackfin/lib/post.c
     board/ssv/common/post.c
     arch/powerpc/cpu/ppc4xx/commproc.c
     arch/powerpc/cpu/mpc512x/common.c
- fixes up the post_word_{load|store} usage;

This doesn't apply any more:

Applying: POST cleanup.
Using index info to reconstruct a base tree...
Falling back to patching base and 3-way merge...
CONFLICT (rename/delete): Rename
board/ssv/common/post.c->tools/gen_eth_addr.c in HEAD and deleted in
POST cleanup.
Removing arch/blackfin/lib/post.c
Auto-merging arch/powerpc/cpu/mpc512x/Makefile
Removing arch/powerpc/cpu/mpc512x/common.c
Removing arch/powerpc/cpu/ppc4xx/commproc.c
CONFLICT (delete/modify): include/configs/ADNPESC1.h deleted in HEAD and modified in POST cleanup.. Version POST cleanup. of
include/configs/ADNPESC1.h left in tree.
Auto-merging include/configs/icon.h
Failed to merge in the changes.
Patch failed at 0001 POST cleanup.
When you have resolved this problem run "git am -i -3 --resolved".
If you would prefer to skip this patch, instead run "git am -i -3 --skip".
To restore the original branch and stop patching run "git am -i -3 --abort".


Please rebase against "next" branch and resubmit.  Sorry for the
inconvenience.

Best regards,

Wolfgang Denk

More than 5 week ago I rebased and resubmitted this patch as you asked
but did not receive any response yet.

Best regards,

Sorry, but this does not apply any more:

Applying: POST cleanup.
Using index info to reconstruct a base tree...
Falling back to patching base and 3-way merge...
Auto-merging arch/blackfin/lib/board.c
CONFLICT (delete/modify): arch/blackfin/lib/post.c deleted in POST cleanup. and modified in HEAD. Version HEAD of arch/blackfin/lib/post.c left in tree.
Removing arch/powerpc/cpu/mpc512x/common.c
Auto-merging arch/powerpc/cpu/ppc4xx/Makefile
Removing arch/powerpc/cpu/ppc4xx/commproc.c
Auto-merging board/barco/barco.c
Auto-merging board/bf537-stamp/Makefile
CONFLICT (content): Merge conflict in board/bf537-stamp/Makefile
Auto-merging include/common.h
Auto-merging include/configs/bf537-stamp.h
Auto-merging include/configs/bfin_adi_common.h
Auto-merging include/configs/katmai.h
Failed to merge in the changes.
Patch failed at 0001 POST cleanup.

The merge conflict in board/bf537-stamp/Makefile is trivial to
resolve, but I'm not sure about the "arch/blackfin/lib/post.c deleted
in POST cleanup. and modified in HEAD."

Please rebase and resubmit.  Thanks.

Best regards,

Wolfgang Denk

Software entities are more complex for their size  than  perhaps  any
other human construct because no two parts are alike. If they are, we
make  the  two  similar parts into a subroutine -- open or closed. In
this respect, software  systems  differ  profoundly  from  computers,
buildings, or automobiles, where repeated elements abound.

Dear Michael Zaidman,

Unfortunately it turns out that the code now contains a few nasty
bugs...

This is a seriously broken design, as it sneaks in storage for a
variable in a storage location where it is not expected.

The "official" layout is that we have CONFIG_SYS_INIT_RAM_BYTES
available; the top CONFIG_SYS_GBL_DATA_SIZE bytes (now
GENERATED_GBL_DATA_SIZE) are used for global data, and the part below
is used for the stack.  No other room is reserved there.

Shifting down the stack by 4 bytes as it's done here causes that the
stack is not correctly aligned any more, which may cause really nasty
subsequent errors.

But it's even worse.

There the same is done, but what happens actually?

Have a look how the stack setup gets implemented in
"arch/powerpc/cpu/mpc512x/start.S":

...
244 in_flash:
245         lis     r1, (CONFIG_SYS_INIT_RAM_ADDR + CONFIG_SYS_GBL_DATA_OFFSET)@h
246         ori     r1, r1, (CONFIG_SYS_INIT_RAM_ADDR + CONFIG_SYS_GBL_DATA_OFFSET)@l
247
248         li      r0, 0           /* Make room for stack frame header and */
249         stwu    r0, -4(r1)      /* clear final stack frame so that      */
250         stwu    r0, -4(r1)      /* stack backtraces terminate cleanly   */
...

As you can see, the code does not use CONFIG_SYS_INIT_SP_OFFSET at
all; instead it performs a calculation which should be redundant, but
in the current code it means that the location of the POST_WORD is
right in the initial stack.

I did not check if the code for other processors has similar issues.

"Reserving" private storage like that is bad, as other involved
parties probably have no knowledge of such a private reservation.

Why do we not simply reserve a word in the global data structure instead?

This bug needs pretty urgent fixing.

Best regards,

Wolfgang Denk

I wish Captain Vimes were here. He wouldn't have  known  what  to  do
either, but he's got a much better vocabulary to be baffled in.

Dear Wolfgang,

Sorry for delayed response, I did not follow the u-boot list for few
weeks an missed your e-mails somehow.
Please see my comments below.

Thanks for catching this, I expected a feedback due to a huge number
of boards and architectures the patch has touched...

There were a number of boards implemented this design (alpr, karef,
katmai, metrobox, ocotea, redwood, taishan, xpedite1000, yucca,
etc...)  I just grouped their definitions in a single place. But, you
are right, it should be fixed.

This code should use the CONFIG_SYS_INIT_SP_OFFSET. This should be
fixed regardless of the POST_WORD location.
I figured out that there a number of architectures that implement this
redundancy.

I guess, because the global data structure is cleared in the
cpu_init_f() upon startup?
	memset ((void *) gd, 0, sizeof (gd_t));

We can prevent part or single field of the gd structure from to be
cleared. Does this make sense to you?

Michael

Please correct me if I am wrong, but the global data structure is
destined to keep its data integrity while switching from flash to RAM.
For this purpose, it is temporary located in the data cache (for those
architectures that do not have static ram on chip) which is available
from very beginning before RAM controller is initialized, afterwards
it is moved into RAM. The POST_WORD is destined for different purpose
- to preserve the data while passing through the watchdog reset and
this is the reason why it was placed into some kind of on chip memory
such as one of unused locations of the PowerQUICC dual port RAM for
mpc8xx/mpc8xxx architectures. In order to achieve the same effect with
data cache the desired data should be locked in the cache prior the
reset and unlocked afterwards. The data cache reaction on the SW reset
is architecture dependent and even if it is possible, that is not
obvious, not sure it worth the effort. For example, any kind of
mpc83xx reset will cause hard reseting of e300 core which in turn will
invalidate caches.


Regards,
Michael

mpc512x related changes are OK. I tested them on mpc5121
based pdm360ng board. Thanks again for this work!
For mpc5121 part you can add
Tested-by: Anatolij Gustschin <agust@denx.de>
