[flashrom] Not able to update firmware with flashrom

[David Hendricks]

Hi Caleb,
It looks like flashrom detected your hardware successfully, however it
found that the management engine region is "locked" (cannot read or write
in that region):
BMWAG 0x00, BMRAG 0x00, BRWA 0x4a, BRRA 0x4b
0x54: 0x00000000 FREG0: Warning: Flash Descriptor region
(0x00000000-0x00000fff) is read-only.
0x58: 0x0fff0700 FREG1: BIOS region (0x00700000-0x00ffffff) is read-write.
0x5C: 0x06ff0003 FREG2: Warning: Management Engine region
(0x00003000-0x006fffff) is locked.
0x60: 0x00020001 FREG3: Gigabit Ethernet region (0x00001000-0x00002fff) is
read-write.
Not all flash regions are freely accessible by flashrom. This is most likely
due to an active ME. Please see http://flashrom.org/ME for details.
Writes have been disabled for safety reasons. You can enforce write
support with the ich_spi_force programmer option, but you will most likely
harm your hardware! If you force flashrom you will get no support if
something breaks. On a few mainboards it is possible to enable write
access by setting a jumper (see its documentation or the board itself).

(For more information: http://flashrom.org/ME)

Consequently, updating your firmware might be tricky. You should probably
use whatever tool the vendor supports, unless you have a specific reason
for using flashrom also have an external programmer handy in case something
goes wrong and you need to recover.
