* Chips like the SST SST25VF080B can only handle single byte writes outside ↵Carl-Daniel Hailfinger2009-05-091-1/+1
| | | | | | | | | | | | | | | AAI mode Change SPI architecture to handle 1-byte chunk chip writing differently from 256-byte chunk chip writing. Annotate SPI chip write functions with _256 or _1 suffix denoting the number of bytes they write at maximum. The 1-byte chunk writing is cut-n-pasted to different SPI drivers right now. A later patch can move them to the generic spi_chip_write_1. Corresponding to flashrom svn r485.
