From 9a795d83fbb8842a271d5e037dc983a57b0419fd Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Wed, 14 Jul 2010 16:19:05 +0000 Subject: Convert SPI chips to partial write However, wrap the write functions in a compat layer to allow converting the rest of flashrom later. Tested on Intel NM10 by David Hendricks. Corresponding to flashrom svn r1080.
