[avrdude-dev] Fix for bug #13693 (can't write to ATMEGA64/128 eeprom with avrdude 5.0-BETA and avrispv2/stk500v2)

[Bernard Fouché]

Hello.

I've applied the following patches and it seems ok for atmega64. Now I 
think that avrdude.conf.in should be also patched for all atmega 
regarding the tokens "read" and "write" (they have to be "read_lo" and 
"write_lo") or stk500v2.c should be patched to look for other parameters 
than AVR_OP_WRITE_LO and AVR_OP_READ_LO, I dunno what's the better 
solution, I leave that to the gurus!
