b8b572e101 powerpc: Move include files to arch/powerpc/include/asm
from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

8d636d8bc5 pasemi_mac: jumbo frame support
First cut at jumbo frame support. To support large MTU, one or several
separate channels must be allocated to calculate the TCP/UDP checksum
separately, since the mac lacks enough buffers to hold a whole packet
while it's being calculated.

Furthermore, it seems that a single function channel is not quite
enough to feed one of the 10Gig links, so allocate two channels for
XAUI interfaces.

8ee9d85779 pasemi: DMA engine management library
pasemi: DMA engine management library

Introduce a DMA management library to manage the various DMA resources
on the PA Semi SoCs. Since several drivers need to allocate these shared
resources, provide some abstractions as well as allocation/free functions
for channels, etc.

40afa53158 pasemi_mac: Move register definitions to include/asm-powerpc
pasemi_mac: Move register definitions to include/asm-powerpc

Move the common register formats and descriptor layouts from
drivers/net/pasemi_mac.h to include/asm-poewrpc/pasemi_dma.h

Previously only the ethernet driver was using them, but other drivers
are coming up that will also use them, so it makes sense to share the
constants.
