I see, then I misunderstood you because you mentioned you "essentially
copied the code from usbasp and renamed everything from usbasp to
avrftdi" which includes usbasp_tpi_read/write_byte,
usbasp_tpi_paged_read/write as well.

As for common code, I think there could be a common chip_erase and
program_enable (like avr_chip_erase or something). It may not be the
best solution, but it's definitely better than having duplicate code
in the different programmers.
