This series add some missing things for an at91sam9g15
board, which gets not mainlined, but there are common
fixes, which are posted with this patchserie.
2 important things:
- enable icache for AT91 based boards
speeds up them a lot, for example reading 8MiB from
an SPI NOR flash into RAM takes with icache off ~15 seconds
with icache enabled only ~5 seconds.
gurnard board defines a board specific enable_caches()
function which enables dcache .. with acomment that this
breaks Ethernet MAC ... I removed this board specific
function, and dcache enable functions should be
added in arch/arm/mach-at91/arm926ejs/cache.c
- SPL clock fix, posted as RFC, as it may breaks other boards.
If so, we may make clock settings in SPL board configurable
through a weak function?
buildman finds no new errors/warnings with the patches
from this patchseries applied.
