Hello Experts,
Does flashrom utility has the capability to program BIOS in a multiple device scenario. In my case, there are two flash devices(each 4MB size) on a SPI interface. The BIOS image build tool we have builds two images of 4MB size, one for flash 1 and other for flash 2. The BIOS sits in the second flash. Now when I issue the command flashrom -w test.bin , does it program the bios region flash?? The test.bin(4MB size) in the command is for the flash 2.  Below is the flash layout.

Flash 1:
------------------------ 4MB
|  ME Region      |
------------------------ 4KB
|  Descriptors    |
------------------------ 0

Flash 2:
------------------------ 4MB
|   BIOS                 |
------------------------ (4MB - BIOS size)
|                              |
------------------------ 0

Appreciate your help.
