Author: snelson Date: Fri Feb 19 01:52:10 2010 New Revision: 907 URL: http://flashrom.org/trac/coreboot/changeset/907
Log: Here's a very quick patch to fix the missing unlock code. Fixes missing unlock for certain chips: * unlock_49lf00x * Pm49fl002 * Pm49fl004
* unlock_49flxxxc * SST49LF160C
* unlock_winbond_fwhub * W39V080FA * W39V080FA (dual mode)
Fixes missing printlock for certain chip: * printlock_w39v040c * W39V040C
