+ help
+ Invalidation of the Instruction Cache operation can

+ help
+ This option enables the workaround for the 430973 Cortex-A8
+ (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
+ interworking branch is replaced with another code sequence at the
+ same virtual address, whether due to self-modifying code or virtual
+ to physical address re-mapping, Cortex-A8 does not recover from the
+ stale interworking branch prediction. This results in Cortex-A8
+ executing the new code sequence in the incorrect ARM or Thumb state.
+ The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
+ and also flushes the branch target cache at every context switch.
+ Note that setting specific bits in the ACTLR register may not be
+ available in non-secure mode.

+ bool "ARM errata: Processor deadlock when a false hazard is created"
+ depends on CPU_V7
+ help
+ This option enables the workaround for the 458693 Cortex-A8 (r2p0)
+ erratum. For very specific sequences of memory operations, it is
+ possible for a hazard condition intended for a cache line to instead
+ be incorrectly associated with a different cache line. This false
+ hazard might then cause a processor deadlock. The workaround enables
+ the L1 caching of the NEON accesses and disables the PLD instruction
+ in the ACTLR register. Note that setting specific bits in the ACTLR
+ register may not be available in non-secure mode.
+
+config ARM_ERRATA_460075
+ bool "ARM errata: Data written to the L2 cache can be overwritten with stale data"
+ depends on CPU_V7
+ 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.
