Hi,
This is V2 of the series to add a UCLASS_CACHE dm driver to handling
the configuration of cache settings. Place this new driver under
/drivers/cache. In this initial revision, the driver is only configuring
what I think are essential cache settings. The more comprehensive cache
settings can be done in the OS.
Diffs from v1:
- Add a DTS bindings document from Linux for the PL310.
- Split up the UCLASS_CACHE addition from the driver patches.
- Add a sandbox cache driver.
- Add a simple test in test/dm/cache.c
- Address comments from Simon Glass.
- Add Reviewed-by's from Marek Vasut.
