[U-Boot] [PATCH 0/6] at91: at91sam9g15 improvements

[Heiko Schocher]

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.
