Re: [coreboot] [PATCH] flashrom: Handle one-byte SPI writes

8 May 2009

Hello,
This might work, but, if I can say, I don't like the idea of renaming the
ich_spi_write to ich_spi_write_256.
1) ich_spi_write() looks to be the generic one, then, this one has the good
name.
2) ich_spi_write() should already use something, stored in the relevant
flashchips[] item, to perform byte, page sector or block write operations. If we
come to make it more "generic", all will have to be renamed back again.
Stephan.
Selon Carl-Daniel Hailfinger c-d.hailfinger.devel.2006@gmx.net:
...
Chips like the SST SST25VF080B can only handle single byte writes
outside AAI mode.
Change SPI architecture to handle 1-byte chunk chip writing differently
from 256-byte chunk chip writing.
Convert all flashchips.c entries with SPI programing to the 256-byte
version by default.
Change the flashchips entry for SST SST25VF080B to 1-byte writing.
Untested.
