The following patches add initial PowerPC 440EPx Sequoia board support.
The code is based mainly on the Bamboo board support by Josh Boyer and
should be applied on top of the "[patch 00/10] 4xx patch series for 2.6.24"
which adds Bamboo support, since Sequoia shares some code pieces with Bamboo.
These patches have been modified based on the comments for the previous
440EPx Sequoia patch series.
The 2.6.24 4xx patch series is included in the following git tree:
git pull git://git.infradead.org/users/jwboyer/powerpc.git for-2.6.24
Thanks,
Valentine.

Surely you need to be more specific than that to select the correct
bd_t structure?
Both TARGET_4xx and TARGET_44x should be selected for 44x. Otherwise I
get wrong bd_t structure (wrong offsets to the eth0/eth1 MAC addresses).
In the older arch/ppc code it used to be CONFIG_4xx and it was selected
for CONFIG_40x and CONFIG_44x as well.

there's no reason to separate sequoia.c from cuboot-sequoia.c
The previous version of Sequoia series had treeboot-sequoia.c, but I've
removed it since only u-boot is used now.
I'm not sure if there are any other bootloaders expected, but is it OK
if I leave 2 separate files just in case? :)

The patches are based mainly on the Bamboo board support by Josh Boyer
and should be applied on top of the "[patch 00/10] 4xx patch series for
2.6.24"
http://ozlabs.org/pipermail/linuxppc-dev/2007-August/040512.html
The 2.6.24 4xx patch series is included in the following git tree:
git://git.infradead.org/users/jwboyer/powerpc.git
Please, take a look at the first message of the thread.
Thanks,
Valentine.

Talking about this, there appears to be more stuff that would need to

CONFIG_440A

Yes, definitely. It's on my TODO list. The "multiplatformness" of 44x
at the moment needs work.
I think this should come as a separate patch, that replaces all these
ifdefs with the FTR_SECTION stuff.
I agree. I'd like to do this as a separate patch later rather than hold
up Sequoia at the moment.

Bootwrapper code for AMCC 440EPx Sequoia board.
The DDR2 Denali controller support has been moved to
arch/powerpc/boot/4xx.c
The code also uses 440EP clocking fixups
initially provided for 440EP Bamboo.

Surely you need to be more specific than that to select the correct
bd_t structure?
Both TARGET_4xx and TARGET_44x should be selected for 44x. Otherwise I
get wrong bd_t structure (wrong offsets to the eth0/eth1 MAC addresses).
In the older arch/ppc code it used to be CONFIG_4xx and it was selected
for CONFIG_40x and CONFIG_44x as well.
Yes, I'm not objecting to those TARGET macros, but I'd be very
surprised if you don't need more to really get the correct bd_t
structure.

Unless another bootloader is expected to come along for Sequoia,
there's no reason to separate sequoia.c from cuboot-sequoia.c
The previous version of Sequoia series had treeboot-sequoia.c, but I've
removed it since only u-boot is used now.
I'm not sure if there are any other bootloaders expected, but is it OK
if I leave 2 separate files just in case? :)
Not unless you have a particular reason to expect another bootloader
will come along, which doesn't seem that likely to me. Or rather the
only likely future bootloader I'd see is newer versions of u-boot
which are device tree aware and handled separately anyway.

Since we should now be able to support both 440GP and 440EP boards in
the same kernel, this probably needs to become a feature section.
Thanks for pointing that out.
Talking about this, there appears to be more stuff that would need to
become feature sections. There're lots of other ifdefs in
arch/powerpc/kernel/head_44x.S, like ifdef CONFIG_PPC_FPU or ifdef
CONFIG_440A
Looks like all these things have to be detected dynamically and
configured properly at runtime since we tend to support more than one
CPU in the same kernel.
Yes, definitely. It's on my TODO list. The "multiplatformness" of 44x
at the moment needs work.
True. Note that not all of them necessarily need to change to feature
sections, though most of them probably do: if the code inside is
harmless, just useless for other platforms it can remain an #ifdef -
the code will run on any kernel with the relevant platform configured.

Fair enough.

Sorry, I don't quite follow.
As far as I can tell the bd_t structure looks OK.
Could you be more specific, please?
What exactly do you think I need to get the correct bd_t?
Thanks,
Valentine.
