Subject: [PATCH 0/2] ARM: at91: add support for L2 cache write_sec() callback

When running under OP-TEE the L2 cache is configured by OP-TEE and
can't be modified for the moment. Add necessary function to get
the current execution world of Linux and add early_setup() callback
that will set the .write_sec() callback for the outer cache.


Clément Léger (2):
  ARM: at91: add sam_linux_is_in_normal_world() function
  ARM: at91: setup outer cache .write_sec() callback if needed
