- 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.
