Since upcoming changes will add several more common pieces of code
between the 32-bit and 64-bit powerpc architectures, it seems best to
unify these two blocks.

I doesn't. I had to add "fsl,lpb", without no localbus nodes show up.
The file arch/powerpc/platforms/52xx/mpc52xx_common.c lists only
"fsl,lpb" as "compatible". Or did I miss something here?

Ouch. Sorry, that was the error. Works perfectly now...
Thanks a lot for your help,

Ah, I guess I didn't merge that fix until 2.6.30. fsl,lpb works for
now. What I wrote about is the recommended value for .30 and later,
just because it is clearer.

I'm back :-)
Not a huge deal per-se, it's just that the patches were merged in Linus
tree only a few hours after being initially submitted it seems, which
doesn't leave much chance for anybody to test, to hit -next, or anything
like that... that was a little bit too trigger happy .

Your special "partition" isn't really a partition then, is it.
Because of that, device nodes to represent your partitions doesn't
work very well.
You really want to use something else, a partition table on the
flash itself for example. Or maybe the (platform? MTD?) code
should create a Linux device for the "full" device.

You cannot claim a name as generic as "partition" for this. Pick
something else if you really must do things this way.

This is a bit of a pity, I take it you can't nest stringify_in_c(). It
is probably worth a comment here about why you're not using PPC_LONG,
otherwise someone will try and "clean it up".

Just call it ASM_MMU_FTR_IF() ? And "string" and "estring" don't mean
much to me.

I assume I was cc'd because I've changed arch/powerpc/kernel/sysfs.c a
couple of times in the last year, but I can't claim to maintain that
code. I'm pretty sure I haven't touched the code in question in this
discussion. I've cc'd linuxppc-dev.

Sure, #if 1 is usually silly. But if the point is that DEBUG_KERNEL is
not supposed to directly affect code generation, then I see two options
for powerpc:
- remove the #ifdef CONFIG_DEBUG_KERNEL guards from
arch/powerpc/kernel/sysfs.c, unconditionally enabling the hid/ima
sysfs attributes, or
- define a new config symbol which governs whether those attributes are
enabled, and make it depend on DEBUG_KERNEL

You could use the compilers at:

Currently x86_64 hosted only, but i686 hosted compilers are building now :)

* [PATCH v2] 83xx: add support for the kmeter1 board.
From: Heiko Schocher @ 2009-04-29 4:48 UTC (permalink / raw)
To: Kumar Gala; +Cc: Scott Wood, linuxppc-dev
In-Reply-To: <20090428163540.GA2193@ld0162-tx32.am.freescale.net>
The following series implements basic board support for
the kmeter1 board from keymile, based on a MPC8360.
This series provides the following functionality:
- The board can boot with a serial console on UART1
- Ethernet:
UCC1 in RGMII mode
UCC2 in RGMII mode
UCC4 in RMII mode
UCC5 in RMII mode
UCC6 in RMII mode
UCC7 in RMII mode
UCC8 in RMII mode
following patch is necessary for working UCC in RMII mode:
http://ozlabs.org/pipermail/linuxppc-dev/2009-April/070909.html
- Flash accessed via MTD layer
On this hardware there is an Intel P30 flash, following patch
series is necessary for working with this hardware:
http://ozlabs.org/pipermail/linuxppc-dev/2009-April/070716.html
- I2C using I2C Bus 1 from the MPC8360 cpu
Signed-off-by: Heiko Schocher <hs@denx.de>
---
changes since v1:
- added comments from Kumar Gala and Scott Wood
- get rid of using get_immrbase() in board specific code
