+ help
+ This option enables the workaround for the 460075 Cortex-A8 (r2p0)
+ erratum. Any asynchronous access to the L2 cache may encounter a
+ situation in which recent store transactions to the L2 cache are lost
+ and overwritten with stale memory contents from external memory. The
+ workaround disables the write-allocate mode for the L2 cache via the
+ ACTLR register. Note that setting specific bits in the ACTLR register
+ may not be available in non-secure mode.
