[PATCH 0/5] Support external CMO to flush entire cache

[Nick Hu]

Some features, such as power management, may require flushing the entire
cache before entering a non-retention power state. To support this, a
simple cache framework is introduced to allow the external CMO to
perform a full cache flush.

Nick Hu (3):
  lib: utils/cache: Add cache flush library
  lib: utils/cache: Add FDT cache library
  lib: utils/cache: Add fdt cmo helpers

Vincent Chen (2):
  lib: utils/cache: Add SiFive ccache controller
  platform: generic: Add SiFive development platform
