Author: hailfinger Date: Tue Nov 23 22:28:16 2010 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. Signed-off-by: Carl-Daniel Hailfinger <[email protected]> Acked-by: Richard A.
