[LinuxBIOS] [patch] flashrom: Fix support for Winbond W39V040FA

[Darmawan Salihun]

Hi all,
   This patch fixes the support for Winbond W39V040FA. I've tested the
patch and it successfully read and write the binary (with verification)
to the flash chip.
   The previous code is able to read but cannot write into the chip
because the block locking registers (BLR) are not set accordingly.

Regards,
