Instead of setting the l2c_aux_val variable in the board code make it possible to set these through device tree and make use of that. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 46129

Subject: [PATCH 72/74] ARM: l2c: clean up l2c_configure()
|
|
|
|
l2c_configure() does not follow the pattern of other l2c_* functions.
|
|
Fix this so that it does to avoid future confusion.
