Subject: [PATCH 0/4] ARM: brcmstb: Add support for the V7 memory map

Hi all,

This patch series updates the brcmstb.S DEBUG_LL routines to dynamically detect
one of the latest STB chip: BCM7278. This chip has a different memory map which
requires use to lookup the main ID register to know whether which register
physical offset we must use.

As a consequence of doing that, we do a number of things:

- allow the inclusion of cputype.h in assembly files to reduce the duplication
  of constants
- define the Brahma-B53 and Brahma-B15 main ID register values, which was long
  overdue
- finaly update brcmstb.S to detect 7278 and offset the base register address
  accordingly

Note that Doug had a slightly different approach in our downstream tree where he
actually added the same MIDR_* constants similar to what ARM64 has, I took that
part away in order to minimize the delta, but I can easily submit that patch
if this is the desired direction moving forward.

Thank you!
