Author: stuge Date: 2008-07-21 19:48:40 +0200 (Mon, 21 Jul 2008) New Revision: 3431
Added: trunk/util/flashrom/w39v040c.c Modified: trunk/util/flashrom/Makefile trunk/util/flashrom/board_enable.c trunk/util/flashrom/flash.h trunk/util/flashrom/flashchips.c Log: flashrom: Winbond W39V040C and MSI K8T Neo2-F
W39V040C does standard JEDEC commands except chip erase so add a small driver. probe_w39v040c() prints the block lock pin status when a chip is found.
The Neo2 board enable matches on 8237-internal IDE and onboard NIC PCI IDs.
Many thanks to Daniel McLellan for testing all of this on hardware! Build tested by Uwe.
