From 42b127fe2244a037a30c5e0f5c686d4ebb70d62f Mon Sep 17 00:00:00 2001 From: Jens Kuehnel Date: Wed, 18 Jun 2008 13:36:34 +0000 Subject: flashrom: Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore Jens sent the first patch that added A49LF040A to flash.h and flashchips.c using _jedec and _49lf040 functions. An issue was found with probe_w29ee011() for the Winbond W29EE011, which caused the A49LF040A to no longer respond to any commands. Ward made a patch to disable probing by default for the W29EE011 following some discussion. Using -c W29EE011 will make flashrom probe for the chip. Peter did some more datasheet diving and found that the Pm49FL00x functions suited this chip quite well because of the block locking registers in A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3. Ward confirmed that this works on alix.2c3 too.
