Cool, thanks! I only reviewed for readability.
Various places check USE_DCACHE_RAM, but this mainboard will aways use
it. Please remove the check and run the code always.

Please use a helper macro for the block below. Suggested macro and
example follows. You may want to perform an automatic search and replace
for this.
