Sascha Hauer 3d76ff9aea ARM: no need to call cache functions when MMU is disabled 
Without MMU enabled we do not need to call __mmu_cache_* as the
caches are not enabled. Calling flush_icache() before jumping
to new code is enough.

Sascha Hauer 9243875971 ARM exceptions: Do not use hardcoded STACK_BASE 
The exception handlers need some space to write to. Traditionally
this has been some stack space. This is not necessary at all, so
just use some variable and get rid of the compile time fixed stack
address.

Sascha Hauer 01525288b0 ARM: Add cpu_architecture() function 
Once we run on multiple SoCs we must know which arm architecture we
are on. Add cpu_architecture() from the kernel to detect it.

Sascha Hauer bad4d7cd75 ARM i.MX gpio: fix of gpio base 
of_alias_get_id() returns the number of the gpio bank, so we have
to multiply with 32 to get the gpio base.

Sascha Hauer 6bb06524d6 ARM pbl: actually create cached mappings in the decompressor 
We called create_sections with 4096MB as size argument, but create_sections
expected the argument in bytes, so create sections was completely optimized
away due to the size >>= 20. This patch changes the size argument to be in
megabytes and adjusts map_cachable to pass the argument in megabytes.

Sascha Hauer a86824b5ac ARM pbl: Provide a dummy error function for the decompressor 
We can't do anything useful in the error function, so we just hang.
This has the advantage that at least when a JTAG debugger is connected
we can see what happens. Otherwise the code just jumps to NULL in case
of an error.
