. Implement the new EECRAddress field in the device descriptor that is
required by the 4.x firmware; make an uneducated guess about what
firmware requires what length of device descriptor -- perhaps Atmel
can be convinced to publish an official matrix for that.
. Specify EECR in the config file where required. Obviously, only
locations that differ from the 0x3c default are mentioned in the
XML files, so by now, this only affects the AT90CAN128 for us.
. After clarification with Atmel, EnablePageProgramming should really
default to 1, and only cleared if specified by an XML parameter. So
far, only the XML files for the ATmega256x and ATmega406 do specify
it at all, and they specify a 1, too.
. Drop the entire OCDEN fuse heuristic. If OCDEN is unprogrammed at
startup, issue a warning that single-byte EEPROM updates won't be
possible. Leave it to the user to program the fuse if desired.
That way, we won't run into any issue of prematurely wearing out the
hfuse EEPROM cell. Interestingly enough, this also solved the
problem of the target not restarting from scratch upon sign-off.
