Subject: [PATCH 0/4] CM L2 prefetch support


This series introduces support for enabling & disabling L2 cache
prefetch units found in systems with CM 2.5 & above (P5600 & I6400 in
terms of currently supported cores). They are enabled by default during
boot and entries are optionally added to DebugFS to enable or disable
prefetching.

Paul Burton (4):
  MIPS: Introduce API for enabling & disabling L2 prefetch
  MIPS: Enable L2 prefetching for CM >= 2.5
  MIPS: Declare mips_debugfs_dir in a header
  MIPS: Allow L2 prefetch to be configured via debugfs
