[PATCHv2 0/4] Xilinx Virtex support for arch/powerpc

[Grant Likely]

2nd version of Xilinx Virtex patches.  I've addressed all the comments
that I've received so far.  This series is just the arch/powerpc support
code.  I'll send the device driver changes in a seperate series for
each driver.

Cheers,
g.

Overall looks pretty darn good.  You dropped the patch to add you as the
Xilinx maintainer.  Oversight?

Also, the support seems fairly generic but I don't see any ml300.dts or
ml4xx.dts files.  And the Kconfig files don't select WANT_DEVICE_TREE.
Are those patches coming later, or do these boards really not need a DTS
file?

I just don't have an OK from Paulus yet.

Those patches are coming later along with a defconfig patch.
