From ad0010a67a9d9fdfe03164bec8d10607b882cec2 Mon Sep 17 00:00:00 2001 From: Michael Karcher Date: Sat, 3 Apr 2010 10:27:08 +0000 Subject: Intel 28F004/28F400 support Remove blockwise write for i82802ab chips. It will be reintroduced in post-0.9.2 in a generic way. This is needed to fix FWH-like chips with non-uniform sectors. These are: Intel 28F001 Sharp LHF00L04 ST M50FW002 ST M50LPW116 Corresponding to flashrom svn r991.
