+WARNING: Do not access chip registers using the i2cdump command, and do not use
+any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
+supported by this driver interpret any access to a command register (including

# *DOCUMENTATION*
This workaround defines cpu_relax() as smp_mb(), preventing correctly
written polling loops from denying visibility of updates to memory.
+config ARM_ERRATA_364296
+ bool "ARM errata: Possible cache data corruption with hit-under-miss enabled"
+ depends on CPU_V6 && !SMP
+ help
+ This options enables the workaround for the 364296 ARM1136
+ r0p2 erratum (possible cache data corruption with
+ hit-under-miss enabled). It sets the undocumented bit 31 in
+ the auxiliary control register and the FI bit in the control
+ register, thus disabling hit-under-miss without putting the
+ processor into full low interrupt latency mode. ARM11MPCore
+ is not affected.
