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 3/3] ARM: BCM5301X: activate some additional options in pl310
|
|
cache controller
|
|
|
|
In the default Broadcom SDK the shared override is activated for this
|
|
cache controller, do the same in the upstream code. Data and
|
|
instruction prefetching is not activated by default for this cache
|
|
controller on the bcm53xx SoC, do it manually like it is done in the
|
|
vendor SDK.
