1108 help
1109 This option enables the workaround for the 743622 Cortex-A9
1110 (r2p0..r2p2) erratum. Under very rare conditions, a faulty
1111 optimisation in the Cortex-A9 Store Buffer may lead to data
1112 corruption. This workaround sets a specific bit in the diagnostic
1113 register of the Cortex-A9 which disables the Store Buffer
1114 optimisation, preventing the defect from occurring. This has no
1115 visible impact on the overall performance or power consumption of the
1116 processor.

1658 this allows for a dual processor. Both processors will share the same
