[PATCH 0/3] Add code for setting coherent pool size

[Marek Szyprowski]

Hi!

Aaro Koskinen and Josh Coombs reported that commit e9da6e9905e639 ("ARM:
dma-mapping: remove custom consistent dma region") introduced a
regresion. It turned out that the default 256KiB for atomic coherent
pool might not be enough. After that patch, some Kirkwood systems run
out of atomic coherent memory and fail without any meanfull message.

This patch series is an attempt to fix those issues by adding function
for setting coherent pool size from platform initialization code and
increasing the size of the pool for Kirkwood systems.
