Hi,
This is V3 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 v2: - Add cache_get_info() to check for non-zero value - Add comments to cache_info struct - Fix up nits from Simon Glass
