    [AVR32] Clean up OCD register usage · 8dfe8f29
    Haavard Skinnemoen authored
    Generate a new set of OCD register definitions in asm/ocd.h and rename
    __mfdr() and __mtdr() to ocd_read() and ocd_write() respectively.
    
    The bitfield definitions are a lot more complete now, and they are
    entirely based on bit numbers, not masks. This is because OCD
    registers are frequently accessed from assembly code, where bit
    numbers are a lot more useful (can be fed directly to sbr, bfins,
    etc.)
    
    Bitfields that consist of more than one bit have two definitions:
    _START, which indicates the number of the first bit, and _SIZE, which
    indicates the number of bits. These directly correspond to the
    parameters taken by the bfextu, bfexts and bfins instructions.
