I chose avr_offset() because once you get to the end of the patchset,
everything uses
offsets to the first byte of the register regardless of endian except for the
avr64
functions (i.e. full becomes the new normal which seems like a fairly standard
expectation for offset).
Really though I don't feel too strongly about this, so would you like me to
rename it
avr_full_offset() to match the existing vsr_full_offset()?
ATB,
Mark.
