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.

This patchset is now pending for more than 1 month ... are there any issues, or do you plan to apply it?
Thanks!
