Subject: [PATCH 1/8 v3] DMA: PL330: use prefix in reg names to build under x86

From: Alessandro Rubini <rubini@...dd.com>

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.

Acked-by: Giancarlo Asnaghi <giancarlo.asnaghi@...com>
---

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.
