[flashrom] [commit] r1235 - trunk

Author: hailfinger

New Revision: 1235
URL: http://flashrom.org/trac/flashrom/changeset/1235

Log:
Add chunked write ability to the Dediprog SF100 driver.

Please note that the write speedup only applies to chips which have SPI
page write (i.e. chips using spi_chip_write_256).

This is a quick fix for write speed until I get around to implementing
full bulk SPI write support.
