f80a3bb252 [ARM] 5318/1: Swap the PRRR and NMRR values in proc-v7.S
A typo caused these values to be swapped leading to incorrect memory
type attributes.

000b502592 [ARM] 5229/3: Replace some ARMv7 opcodes with the instruction name
These instructions were placed in the code directly as opcodes because
early compilers didn't support them. Toolchains supporting ARMv7
understand these instructions and the patch puts the mnemonics back.

5ec9407dd1 [ARM] Don't include asm/elf.h in asm code
asm code really wants asm/hwcap.h, so include that instead.

da0916539d [ARM] Convert set_pte_ext implementions to macros
There are actually only four separate implementations of set_pte_ext.
Use assembler macros to insert code for these into the proc-*.S files.

93ed397011 [ARM] 5227/1: Add the ENDPROC declarations to the .S files
This declaration specifies the "function" type and size for various
assembly functions, mainly needed for generating the correct branch
instructions in Thumb-2.

4a1fd556c1 [ARM] fix 48d7927bdf
The proc-*.S files have the _prefetch_abort pointer placed at the end
of the processor structure but the cpu-multi32.h defines it in the
second position. The patch also fixes the support for XSC3 and the
MMU-less CPUs (740, 7tdmi, 940, 946 and 9tdmi).

48d7927bdf Add a prefetch abort handler
This patch adds a prefetch abort handler similar to the data abort one
and renames the latter for consistency. Initial implementation by Paul
Brook with some renaming by Catalin Marinas.

The auxiliary control and the L2 auxiliary control registers are
Cortex-A8 specific. They need to be removed from the generic ARMv7
