[U-Boot] [PATCH v3 0/4] ARM & m68k: cache: add weak cache code then enable usb cache support

[Josh Wu]

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.
