[PATCH 1/8 v3] DMA: PL330: use prefix in reg names to build under x86
From: Davide Ciminaghi
Date: Fri Nov 23 2012 - 20:06:52 EST
From: Alessandro Rubini <rubini@xxxxxxxxx>
This driver would not compile if ARM_AMBA is selected under x86,
because "CS" and "DS" are already defined there. But AMBA
is used in the x86 world by a PCI-to-AMBA bridge, to be submitted.
The patch just adds the "PL330_" prefix to all register and bit fields,
so it can be built by randomconfig after ARM_AMBA appears within x86.
No other technical changes have been performed.
The patch was build-tested only.

---
The patch is very big, but what it actually does is just renaming the pl330
registers.
As requested by Viresh Kumar, what follows is the output of
git diff --word-diff b9740f9~..b9740f9
This format should allow better readability for reviewing.
Note that 'index' and '@@' strings at the beginning of lines
have been escaped by adding a leading '#' to avoid errors while actually
applying the patch.
The changelog has also been slightly adjusted with respect to 1/8 v2, so
I'm resending as v3.
