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 71/74] ARM: l2c: write auxiliary control register first
|
|
|
|
Before calling the controller specific configuration function, write
|
|
the auxiliary control register first, so that bits shared with other
|
|
registers (such as the prefetch control register) are not overwritten
|
|
by the later write to the auxctrl register.
