Thanks for the latest patch! Read works as expected, the file I read
looks good.

Write does not work as of yet. Here is the output:

$ sudo ./flashrom -p satamv -w 9445_rev5.bin
flashrom v0.9.7-r1769 on Linux 3.2.48-logicube-ng.16-bfq (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found Winbond flash chip "W25X40" (512 kB, SPI) on satamv.
Reading old flash chip contents... done.

Uh oh. Erase/write failed. Checking if anything changed.
Good. It seems nothing was changed.
Writing to the flash chip apparently didn't do anything.
Please check the connections (especially those to write protection pins) between
the programmer and the flash chip. If you think the error is caused by flashrom
please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org, thanks!
