SST25VF040B using 0x90 identification and AAI write

Browse Source 
SST AAI is Auto Address Increment writing, a streamed write to the flash chip
where the first write command sets a starting address and following commands
simply append data. Unfortunately not supported by Winbond SPI masters.

From July 2008.

Corresponding to flashrom svn r407 and coreboot v2 svn r3913.
