This series add empty stub for invalidate/flush dcache functions, so that usb driver can enable cache support.
Also it include patch to clean up the ARM cache code: - add weak functions for flush_cache(). - make them use the weak function flush_cache(). - remove not used code in flush_cache() in lib/cache.c.
Changes in v3: - add Angelo's Acked-by. - remove the same functions in the cpu/ files as they will use the weak function provided in lib/cache.c
Changes in v2: - CONFIG_DM_USB in periodic_unlink() should be remove as well. This version remove it. - Add Hans de Goede's acked-by.
