Please Cc Randy Dunlap <rdunlap@xenotime.net> for kernel documentation
patch.

Why do we keep TODO in this doc?

Hi, Mahesh,
Your patch seems have some style problems... checkpatch.pl complains,
total: 330 errors, 1 warnings, 355 lines checked
NOTE: whitespace errors detected, you may wish to use scripts/cleanpatch or

Could use scripts/checkpatch.pl to check your patch?

I think this patch can be folded into the 02/10, as this config

Although they are static functions, it is still better to name them

I do run the checkpatch.pl before sending patches out. I am not sure how

1. why make the change
2. if you're using FSL_CORENET as a SoC feature CONFIG option than other =
bits of this patch are wrong
It should NOT be used in platforms/85xx/Makefile those should be left =
alone and FSL_CORENET should be selected by having E500MC or similar =
set.

Nak, I don't want to add a unique build option for 64-bit E5500 vs =
E500MC. We have E6500 coming and I don't want to introduce =
CONFIG_FSL_E6500 at that point.

So its clear from the community that there is confusion here and we need =
to clean this up. I guess my attempt to support an kernel that ran on =
both E500v2 and E500mc isn't worth it. However I don't want to =
completely remove the ability to do this.
Towards the cleanup I'd ask for a proposal on what exactly the CONFIG_ =
options we'd end up with would be and their meaning.
So today we have:
CONFIG_E500
CONFIG_PPC_E500MC
What do we want to move to? I want to keep the builds such that we have =
only 2 classes: e500V1/V2 and e500mc/e5500/e6500/.../eX500. I see no =
reason to hyper-optimize e500mc vs e5500 vs e6500.

I'm with Kumar on this. I don't see the point of making it so complicated. No kernel should ever have to care with a DT is 64-bit or 32-bit. If you build a kernel with 64-bit phys support, then it will work with any DT.
U-Boot already warns you if the DT and the actual physical addresses of the devices don't match.
There are only two reasons to create a 32-bit kernel:
1) A small performance improvement on systems with 2GB or less.
2) Some SOC devices only support 32-bit physical addresses, so the easiest way to ensure a compatible address is to prohibit memory above 4GB.
Item #2 is not something that we really worry about. It's only a real problem on true 64-bit kernels, and in those cases, we cannot build a kernel with 32-bit phys support, so the driver needs to handle it internally.

* [PATCH 02/11] powerpc/85xx: Simplify P1020RDB CAMP dts using includes
From: Kumar Gala @ 2011-11-10 16:07 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <1320941229-29557-1-git-send-email-galak@kernel.crashing.org>
If we include the p1020rdb.dts instead of p1020si.dts we greatly reduce
duplication and maintenance. We can just list which devices are
disabled for the given core and mpic protected sources.

* [PATCH 01/11] powerpc/85xx: Add 'fsl, pq3-gpio' compatiable for GPIO driver
From: Kumar Gala @ 2011-11-10 16:06 UTC (permalink / raw)
To: linuxppc-dev
Support MPC85xx platforms outside of MPC8572/MPC8536. The
MPC8572/MPC8536 have an erratum that is worked around based on having
"fsl,mpc8572-gpio" in the compatiable list. All other MPC85xx SoCs
don't require this workaround and thus utilize the 'fsl,pq3-gpio'
compatiable.
