Subject: [PATCH 1/8] 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 adds the "PL330_" prefix to all register and bit fields,
so it can be built by randomconfig after ARM_AMBA appears within x86.
