Hi Paul,

Please pull from:

 master.kernel.org:/pub/scm/linux/kernel/git/jwboyer/powerpc-4xx.git for-2.6.26

to pick up the first round of 4xx patches for 2.6.26.  There are a few
new board ports, some Xilinx driver updates, and some DCR helper
macros.

Grant has two bootwrapper patches that I would like to see go in as
well, but I need to test them a bit more first.

These two commits have been dropped from the branch.  They cause the
allyesconfig build for powerpc to fail because CONFIG_PPC_DCR_MMIO
doesn't understand the dcri_clrset macro.

Crap.  Looks like you already pulled the tree.  We need to either
revert those two commits, or essentially define dcri_clrset to a do {}
while(0) in include/asm-powerpc/dcr-mmio.h so things build.

"... so things build."  Relax Ben.  That isn't a final solution.

I'd rather just do an outright revert of the commits for now.

For a final solution, we're going to have to come up with a more clever
way of doing the clocking stuff in ibm_newemac.  The SDRs are board
specific and completely outside of EMAC/MAL itself.  So doing a dcr_map
on it becomes a bit more difficult, since there really isn't an SDR
node in the device tree at the moment.

Not board specific... chip specific.

That is why I tried hard to avoid the bloody workarounds...
unfortunatly, the HW is crap enough that we have no real choice here.

Hi Paul,

Please pull from:

 master.kernel.org:/pub/scm/linux/kernel/git/jwboyer/powerpc-4xx.git for-2.6.26

to pick up a small number of fixes for 4xx.  One corrects the PCI
addresses for Sequoia boards, another fixes TLB issues with newer 440x6
cores.  Stefan's pci-e endpoint driver is also included here as it is
a fairly contained change with Ben's Ack.  It should have been included
in my last pull request, but I missed it and have been out.

thx,

Hi Paul,

Please pull from:

to pick up one bugfix for 4xx.  This patch works around an errata for

The tree is based off of Linus' 2.6.26-rc3.  If you've no objections
or other patches queued up, Linus can pull directly if he'd like.
