    MIPS: generic: Convert SEAD-3 to a generic board · 3f5f0a44

    Convert the MIPS SEAD-3 board support to be a generic board, supported
    by generic kernels.
    
    Because the SEAD-3 boot protocol was defined long ago and we don't want
    to force a switch to the UHI protocol, SEAD-3 is added as a legacy board
    which is detected by reading the REVISION register. This may technically
    not be a valid memory read & future work will include attempting to
    handle that gracefully. In practice since SEAD-3 is the only legacy
    board supported by the generic kernel so far the read will only happen
    on SEAD-3 boards, and even once Malta is converted the same REVISION
    register exists there too. Other boards such as Boston, Ci20 & Ci40 will
    use the UHI boot protocol & thus not run any of the legacy board detect
    functions.
