1070 (r2p0..r2p2) erratum. Under certain conditions, specific to the
1071 Cortex-A9 MPCore micro-architecture, two CPUs working in SMP mode,
1072 accessing some data located in the same cache line, may get corrupted
1073 data due to bad handling of the address hazard when the line gets
1074 replaced from one of the CPUs at the same time as another CPU is
1075 accessing it. This workaround sets specific bits in the diagnostic
1076 register of the Cortex-A9 which reduces the linefill issuing
1077 capabilities of the processor.

1652 Virtual SMP uses the processor's VPEs to implement virtual
1653 processors. In currently available configuration of the 34K processor
1654 this allows for a dual processor. Both processors will share the same
1655 primary caches; each will obtain the half of the TLB for it's own
1656 exclusive use. For a layman this model can be described as similar to
1657 what Intel calls Hyperthreading.

1677 On currently available 34K processors this means a Linux system will
1678 see up to 5 processors. The implementation of the SMTC kernel differs
1679 significantly from VSMP and cannot efficiently coexist in the same
1680 kernel binary so the choice between VSMP and SMTC is a compile time
1681 decision.
