c6201553ba ARM926EJS: Make asm routines volatile in cache ops
We certainly don't want the compiler to reorganise the code for dcache flushing.

c8d9ceaf06 ARM: 926ejs: use debug() for misaligned addresses
Misaligned warnings are useful to debug faulty drivers.
A misaligned warning is printed also when the driver
is correct - use debug() instead of printf().

679530278d arm, arm-kirkwood: disable l2c before linux boot
The decompressor expects the L2 cache to be disabled. This fixes booting
some kernels, which have CONFIG_ARM_PATCH_PHYS_VIRT enabled.

076cd49ad1 arm926ejs: remove noop flush_dcache_all function
Commit 2f3427c added noop cache functions implementation for arm926ejs
to fix compilation of drivers depending on these functions (DaVinci
EMAC in particular).

Unfortunately, the bug was introduced: noop implementation calls
dcache_disable which calls flush_dcache_all which in turn calls
dcache_disable thus creating an infinite loop.

This patch removes noop implementation for flush_dcache_all, we already
have default one in arch/arm/lib/cache.c and it should be used instead.

2f3427ccb9 arm926ejs: add noop implementation for dcache ops
Added noop implementation for dcache operations that will buzz
about missing real implementation and disable the dcache.
This fixes compilation of DaVinci EMAC driver on arm926ejs.
