Author: stefanct Date: Fri Apr 19 03:59:15 2013 New Revision: 1671 URL: http://flashrom.org/trac/flashrom/changeset/1671
Log: Add support for PMC Pm25LD series. This patch adds support for - Pm25LD256C - Pm25LD512(C) - Pm25LD010(C) - Pm25LD020(C) - Pm25LD040(C) These seem to be the successors of the Pm25LV series. The main difference seems to be the dual I/O and additional erase opcodes. Some support an additional, complex locking register (maybe all of the above, but available datahsheets do not indicate it for all). The Pm25LD512C was tested by Chi Zhang: http://paste.flashrom.org/view.php?id=1579 Signed-off-by: Stefan Tauner <[email protected]> Acked-by: Stefan Tauner <[email protected]> Modified:
