Reinhard Meyer provided a good summary of the current mess of ARM
relocation related config options we have at the moment, cf.
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/87679/focus=87842
Given the fact that ARM boards need to be adapted to the new
relocation support anyway, we may as well take this opportunity and
make the code a bit cleaner and easier to read. It is supposed that
this will make the neccessary adapptions just easier.
NOTE: this patch series is in violation with the grace period
announced in doc/feature-removal-schedule.txt, but actually we don;t
make the situation any worse, as CONFIG_SYS_ARM_WITHOUT_RELOC does not
work anyway.
Wolfgang Denk (3):
Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_BROKEN_RELOC_FIXUP
Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
Drop support for CONFIG_SKIP_RELOCATE_UBOOT

By now, the majority of architectures have working relocation
support, so the few remaining architectures have become exceptions.
To make this more obvious, we make working relocation now the default
case, and flag the remaining cases with CONFIG_BROKEN_RELOC_FIXUP.

From: Wolfgang Denk @ 2010-10-28 19:12 UTC (permalink / raw)
To: u-boot
When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support. However, other recent changes led to a different
implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.
So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

-What: CONFIG_SYS_ARM_WITHOUT_RELOC option
-When: After Release 2011.03
-
-Why: The implementation of U-Boot for the ARM architecture has
- been reworked to support relocation. This allows to
- efficiently use the same U-Boot binary image on systems with
- different RAM sizes, and brings the implementation much more
- in line with the code used for example on Power Architecture
- systems (eventually allowing to merge into common code). This
- seems especailly interesting now that ARM is getting Device
- Tree support as well.
-
- All ARM boards need to be adapted to this new code, which
- requires testing on the actual hardware, so this is a task
- for the respective board maintainers or other users.
-
- Please see the commit message of commit f1d2b31 for details:
-
- http://git.denx.de/?p=u-boot.git;a=commit;h=f1d2b31
-
- Support for CONFIG_SYS_ARM_WITHOUT_RELOC will be removed
- after release v2011.03; all boards that have not been
- converted by then, i. e. that are still broken then, are
- considered unmaintained and without interest for the
- community and will be removed as well.

From: Wolfgang Denk @ 2010-10-28 19:12 UTC (permalink / raw)
To: u-boot
For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().
With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway. So don't keep this relict any
longer.

Dear Wolfgang Denk,

Seems a slight misnomer to me, and a bit hides what it really does. What about
CONFIG_NEEDS_DATA_RELOC_FIXUP ?

Maybe for a future patch series:
Move all not ARM variant/not SoC specific parts (setting up stack, calling C
functions, relocation and relocation fixup) to a common file
(arch/arm/lib/generic_start.S), basically leaving only specific parts in the
various arch/arm/cpu/*/start.S files. This would highly ease maintenance.
Best Regards,
Reinhard

Agreed. But that needs to be done by someone who has a clue about
ARM; I'm just an old patch-monkey when it comes to that.

Tested this 3 patches on the qong, magnesium, tx25 and omap3_beagle
board. Works fine. So:
Tested-by: Heiko Schocher <hs@denx.de>

Yep, I thought about this too, as I made the relocation stuff, but
I decided to think about that in a second step...

Thinking about that, I feel the name is too long. And eventually not
clear enough either.
How about CONFIG_NEEDS_MANUAL_RELOC ?

OK, since I had that in mind, too. I skipped it however since "manual" for me
smells like really some extra manual labour.
But I guess any full descriptive term would be too long.
Fact is, that that sort of system wide "manual" reloc is needed for "initialized data
with pointer contents" only. It would be nice if that fact would peek out to
avoid conceptional misunderstandings.
Would it be possible for you to apply those 3 patches to a testing branch, I am
having an odd error trying to git-am patch 2/3, however I can find no wrongs in the
patch at the complained about places. 1/3 did apply without problems.
Best Regards,
Reinhard

Yes, that's what I think too.
OK, renamed into CONFIG_NEEDS_MANUAL_RELOC.

Tested this 3 patches on the top9000 board (not mainline, at91sam9xe512).
Works fine. So:
Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

Wait... This is the other way around, isn't it? When a board defines
CONFIG_RELOC_FIXUP_WORKS, it means "no need to do manual fixups", I think.

Yes, that was the case with CONFIG_RELOC_FIXUP_WORKS. but this is what
we consider standard today, so we don't define this normally.
Instead, for the few architectures that need it, we define now
CONFIG_NEEDS_MANUAL_RELOC.
Of course the logic of the conditions needed to be inverted, i. e. I
changed
#if !defined(CONFIG_RELOC_FIXUP_WORKS)
into
#if defined(CONFIG_NEEDS_MANUAL_RELOC)
