Details:
In rev 1.22 of avr910.c, the cache for the high byte in
avr910_read_byte_flash() has been turned off. This happened
as a consequence of applying patch #3277 which claims to
fix several problems with paged writes.
However, as the code looks now, avr910_read_byte_flash()
cannot return a high byte anymore at all.
Either the claim of patch #3277 proves bogus, then the byte
cache should be turned on again, or we have to take care in
avr910_read_byte_flash() to extract the correct byte out of
those two bytes returned in response to the `R' command.
