Supporting the ARM926EJ-S Variant

The processor used in this SoC is a variant of the generic ARM9 core, the ARM926EJ-S. A few tweaks were needed in the generic ARM configuration code to provide support for this variant. Note that this is nothing like providing full support for any new features in a variant core, but just getting the core to be recognized as an ARM9 variant by the system. Note also that the latest version of NetBSD fully supports this processor, so these mods are no longer required.

arch/arm/arm32/cpu.c

an addition was made to the CPU identifier list cpuids[]:

{ CPU_ID_ARM926EJS, CPU_CLASS_ARM9ES, "ARM926EJ-S", generic_steppings }

a change was propagated from a more recent kernel version to wtnames[14]:

 "**unknown 14**" to "write-back-locking-C"

arch/arm/include/armreg.h

the identifier for this ARM9 variant was added to CPU arch type defines:

CPU_ID_ARCH_V5TEJ   0x00060000

the ID for this variant was added to CPU ID defines:

#define CPU_ID_ARM926EJS    0x41069260
