+ 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.
