[U-Boot] [PATCH v3 0/4] arm: changes in cache handling

[Aneesh V]

- Avoid enabling caches for all ARM boards
- Enable caches for omap3/4
- Stronger barrier for armv7 cache-maintenance operations.

V2:
* Rebased to latest HEAD of u-boot/master
* Improved the README
* Added a patch for removing the flush in invalidate
  and for printing a warning in such cases.

V3:
* Improve the error message on un-aligned invalidate

Aneesh V (4):
  arm: do not force d-cache enable on all boards
  omap: enable caches at system start-up
  armv7: stronger barrier for cache-maintenance operations
  armv7: cache: remove flush on un-aligned invalidate
