From f52f784bb300ec0acbd6c6bd9e6c3e5b435c4a90 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Fri, 8 Oct 2010 18:52:29 +0000 Subject: Move implicit erase out of chip drivers Flashrom had an implicit erase-on-write for most flash chip and programmer drivers, but it was not entirely consistent. Some drivers had their own hand-rolled partial update functionality which made handling partial updates from generic code impossible. Move implicit erase out of chip drivers, and kill some dead erase functions at the same time. A full chip erase is now performed in the generic code for all flash chips on write, and after that the whole chip is written. Corresponding to flashrom svn r1206.
