bool "ARM errata: DMB operation may be faulty"
depends on CPU_V7 && SMP
help
This option enables the workaround for the 742230 Cortex-A9
(r1p0..r2p2) erratum. Under rare circumstances, a DMB instruction
between two write operations may not ensure the correct visibility
ordering of the two writes. This workaround sets a specific bit in
the diagnostic register of the Cortex-A9 which causes the DMB
instruction to behave as a DSB, ensuring the correct behaviour of
the two writes.
config ARM_ERRATA_742231
bool "ARM errata: Incorrect hazard handling in the SCU may lead to data corruption"
depends on CPU_V7 && SMP
help
This option enables the workaround for the 742231 Cortex-A9
(r2p0..r2p2) erratum. Under certain conditions, specific to the
Cortex-A9 MPCore micro-architecture, two CPUs working in SMP mode,
accessing some data located in the same cache line, may get corrupted
data due to bad handling of the address hazard when the line gets
replaced from one of the CPUs at the same time as another CPU is
accessing it. This workaround sets specific bits in the diagnostic
register of the Cortex-A9 which reduces the linefill issuing
capabilities of the processor.
