Support for ST-Ericsson U300 series mobile platforms.
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.
+
+config ARM_ERRATA_764369
+ bool "ARM errata: Data cache line maintenance operation by MVA may not succeed"
+ depends on CPU_V7 && SMP
+ help
+ This option enables the workaround for erratum 764369
+ affecting Cortex-A9 MPCore with two or more processors (all
+ current revisions). Under certain timing circumstances, a data
+ cache line maintenance operation by MVA targeting an Inner
+ Shareable memory region may fail to proceed up to either the
+ Point of Coherency or to the Point of Unification of the
+ system. This workaround adds a DSB instruction before the
+ relevant cache maintenance functions and sets a specific bit
+ in the diagnostic control register of the SCU.
