4e218b9928 ARM: debug: move PL01X debug include into arch/arm/include/debug/
Now that the PL01X debug include can mostly stand alone without
requiring platforms to provide any macros, move it into the debug
directory so it can be directly included.  This allows us to get rid of
a lot of debug-macros include files.

The autodetect case for Versatile Express and the ux500 are left alone;
these are more complicated implementations.

5c972af407 ARM: debug: provide PL01x debug uart phys/virt address configuration options
Move the definition of the UART register addresses out of the platform
specific header files into the Kconfig files.

ed18bdc875 ARM: vexpress: Add Cortex-R Series UART, selectable via DEBUG_LL
The Cortex-R series processors on Versatile Express have a different memory
map to the RS1 and CA9X4 tiles. Most of the platform difference can be
expressed in device-trees, but the UART definitions for LL_DEBUG cannot.

This patch defines the UART location for R-Series processors on
versatile-express, allowing low-level debug and output from the decompressor.
These definitions are selectable via Kconfig

d892a91730 ARM: vexpress: fix ll debug code when building multiplatform
After "ARM: vexpress: Make the debug UART detection more specific",
building allyesconfig in linux-next now gives me:

arch/arm/kernel/debug.S: Assembler messages:
arch/arm/kernel/debug.S:81: Error: selected processor does not support ARM mode `movw r2,#0xc 091'
arch/arm/kernel/debug.S:81: Error: selected processor does not support ARM mode `movt r2,#0x4 10f'

arch/arm/kernel/debug.S:104: Error: selected processor does not support ARM mode `movt r3,#0x 410f'

Since the code can never get executed on ARMv6 but might
be built in a configuration that has ARMv6 enabled, it's
safe to just mark it in the assembly source for being
ARMv7-only.

852663d94f ARM: vexpress: Make the debug UART detection more specific
Base the UART detection heuristic on architecturally defined
MIDR register instead of implementation dependent CBAR. The
only tile using the original memory map is V2P-CA9 with Cortex
A9 r0p1, which MIDR contains value 0x410fc091.
