    sh: SH7760 DMABRG support. · fc467a26
    Manuel Lauss authored
    The DMABRG is a special DMA unit within the SH7760 which does data
    transfers from main memory to Audio units and USB shared memory.
    It has 3 IRQ lines which generate 10 events, which have to be masked
    unmasked and acked in a single 32bit register. It works independently
    from the tradition SH DMAC, but blocks usage of DMAC channel 0.
    
    This patch adds 2 functions to associate callbacks with DMABRG events
    and initialization.
