Every SPI programmer driver had its own completely different chip write implementation, and all of them were insufficiently commented. Create spi_write_chunked as a copy of spi_read_chunked and convert all SPI programmers to use it. No functional changes except:
- Bus Pirate uses 12 Byte writes instead of 8 Byte writes
- SB600 uses 5 Byte writes instead of 1 Byte writes
Should work. Not for 0.9.1, but since I had that thing on my disk anyway, I figured I'd post it to the list in case someone wants to experiment with partial writes. Tests appreciated.
Looks like a step in the right direction to me, I'd love to see it post 0.9.2. I even had a chance to test it on Intel and VIA SPI controllers, and it seemed not to break anything :-)
