Guillaume Tucker aa273a3236 ARM: 9007/1: l2c: fix prefetch bits init in L2X0_AUX_CTRL using DT values ... [ Upstream commit 8e007b367a ] The L310_PREFETCH_CTRL register bits 28 and 29 to enable data and instruction prefetch respectively can also be accessed via the L2X0_AUX_CTRL register. They appear to be actually wired together in hardware between the registers. Changing them in the prefetch register only will get undone when restoring the aux control register later on. For this reason, set these bits in both registers during initialisation according to the devicetree property values.
