* [patch 1/4] autoselect optimal -mcpu= flag by platform
From: Arnd Bergmann @ 2007-08-29 23:11 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev@ozlabs.org
In-Reply-To: <20070829231122.406817286@arndb.de>
We can choose the -mcpu= gcc flags for compiling the kernel
based on the platform that we build for. In case of multiplatform
kernels, this chooses a setting for a common subset.
When using a platform type that can use different CPUs, a
new option CONFIG_PPC_CPU_SELECTION can be enabled to select
more specifically which CPUs the kernel will be able to
run on.
This replaces the CONFIG_POWER4_ONLY option with an much more
generic approach.
Also, when CONFIG_PPC_CPU_SELECTION is set, it is now possible
to select a CPU to tune for by means of the -mtune= option.
I tried to be very careful when coding the specific rules into
the Kconfig language, but it would be good to have a few
people sanity-checking them.

* [patch 2/4] move embedded6xx into multiplatform
From: Arnd Bergmann @ 2007-08-29 23:11 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev@ozlabs.org
In-Reply-To: <20070829231122.406817286@arndb.de>
The various embedded 6xx systems can easily coexist
in one kernel together with the other 6xx based systems,
so there is no strict reason to keep them separate.
This also fixes a problem introduced in one earlier
patch, where the embedded 74xx based systems could
not automatically select altivec any more.

* [patch 0/4] CPU selection Kconfig cleanup, take 7
From: Arnd Bergmann @ 2007-08-29 23:11 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev@ozlabs.org
One of these days, I hope to get the patches in ;-)
No changes since the last version I sent for 2.6.23, aside
from making the patch apply cleanly to for-2.6.24.
Paul, please apply the first two patches, as well as the remaining
two if Kumar agrees.

* [patch 4/4] move 83xx into multiplatform
From: Arnd Bergmann @ 2007-08-29 23:11 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev@ozlabs.org
In-Reply-To: <20070829231122.406817286@arndb.de>
MPC83xx based machines don't need their own kernel,
but can run one that is shared with the other 6xx
compatible machines, so we should allow that
in Kconfig.

* [patch 3/4] move 86xx into multiplatform
From: Arnd Bergmann @ 2007-08-29 23:11 UTC (permalink / raw)

MPC86xx based machines don't need their own kernel,
but can run one that is shared with the other 6xx
compatible machines, so we should allow that
in Kconfig.

Kumar, I don't remember if you still had objections
to merging 86xx annd 83xx into multiplatform after
our last discussion.
Please Ack or Nack the two patches.

No, it is not wrong. The behaviour is just not defined by the
standard, so the compiler is free to do what he likes. Some systems
default to singend chars, others to unsigned. Both is perfectly
legal.
It is code that makes any such assumptions which is broken.

No, that is *way* too old.
The number after the "-g" is the (initial 8 digits of the) git commit
ID. You can use this to identify a spoecific version in the git
repository.

As mentioned above, with arch/powerpc you always need a device tree
blob.

* Xilinx Virtex boot
From: Robert Woodworth @ 2007-08-29 23:34 UTC (permalink / raw)
To: linuxppc-embedded
I'm trying to port Linux to a new Virtex Platform. The kernel will not
uncompress, I get the following on the console:
loaded at: 00400000 004FB19C
board data at: 004F9120 004F919C
relocated to: 00404054 004040D0
zimage at: 00404E50 004F8409
avail ram: 004FC000 04000000
Linux/PPC load: console=ttyUL root=/dev/xsa2
Uncompressing Linux...
zlib_inflateInit2 returned 00506530
exit
Any ideas what causes this error??
Is something mis-configured on my EDK project?
I have 64MB DDR on the OPB *not* the PLB.
Is that a problem??

Subject: spu_manage: fix spu_unit_number for celleb device tree
From: Christian Krafft <krafft@de.ibm.com>
This fixes a regression introduced with 2.6.23-rc4 after on some
confusion about the device tree interfaces.
IBM QS21 device trees provide "physical-id", so we changed the code to
run on that and remain compatible with all IBM machines.
However, the Toshiba Celleb device tree provides the "unit-id" property,
which was in the Linux code, but never used in this way on IBM hardware.
Legacy device tree used the reg property for the physical id of an spe.
This patch fixes find_spu_unit_number to look for the spu id in that order.
The length is checked to avoid misinterpretation in case the attributes
unit-id or reg do not contain the id.

Possibly, do you know that EDK has your ram is configured correctly

It shouldn't be the problem, but why are you doing that?

Heh, I was just implementing an equivalent function in libfdt

This one is obsoleted by my recent patch which moves both strncmp()
and strchr() to string.S.

Hrm.. I think the --binary option at least should be removed, and
subsumed into the platform id - all other binary formats are selected
by the platform name at present.
And I think it's probably best to do that for --fixed-entry as well,
although it's a bit less clear there.

Sorry, as I read later patches in the series, I realised your config
option didn't do what I thought it did when I said that.
Am I correct in thinking that it's basically an arch/ppc versus
arch/powerpc thing. In which case couldn't you use CONFIG_PPC_MERGE
instead?

Well, I'm just working of the example of 4xx EMAC. The way it does
mdio, it wants a handle on the mdio bus to perform various operations
there as well on the phy to tell it how to address them. fsl-enet may
do things differently and have no particular need for such a handle.
