[flashrom] [PATCH v3] Add IT8212F as programmer
Kyösti Mälkki
kyosti.malkki at gmail.com
Thu Sep 6 10:05:52 CEST 2012
This PCI PATA controller can use 3V parallel flash upto 128kB.
My card was identified as:
PCI 1283:8212, subsystem 1283:0001.
and labelled as:
Innovision Multimedia LTD.
EIO ATA133 RAID
(DM-8401 Ver A)
This particular card did not require setting of any GPIO signals to
enable flash writing. My card has Pm39LV512 in PLCC32 package without
socket.
