[flashrom] Flash Marvell 91xx Config PROM

[PETER ANDERSON]

Hi,

I have a Asus motherboard (p7p55d-e pro) with (I believe) an onboard Marvell
9120 Sata 3 controller.  I also have an add on  card Sata controller with a
Marvell 9123 chip.  When I updated my firmware, both devices were found and
updated but upon reboot the "on board" Marvell Controller is bricked.  It no
longer appears in the boot up/bios sequence.

I'm looking for a way to flash the chip back preferably in circuit.  Is this
something flashrom can do?  The Marvell Flash device is macronix MX25L4005A.

Thanks,
Pete

 I'm pretty sure this is the controller that's not responding
