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.
