From ec9e6e33a4d08c4b5afcc51cc5a964e1208731fc Mon Sep 17 00:00:00 2001 From: Peter Stuge Date: Mon, 21 Jul 2008 17:48:40 +0000 Subject: [PATCH] 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.
