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