    ARM: document and update UNCACHEABLE_ADDR definitions · c94e4ad2

    Document the UNCACHEABLE_ADDR definitions for footbridge and SA1100
    so that we know where they're located and/or what they're accessing.
    Change RiscPC to calculate the UNCACHEABLE_ADDR value from FLUSH_BASE
    as that's where we locate that.
    
    UNCACHEABLE_ADDR is used to perform an uncached access (ARMv4
    terminology) necessary to force a CPU clock-switch to the memory-
    speed clock, as required for entering WFI.
