I have taken the Flash Region's dump of my vendor BIOS using Ifdtool (which
is copied below),
* Flash Region 0 (Flash Descriptor): 00000000 - 0000ffff *
* Flash Region 1 (BIOS): 00200000 - 007fffff *
* Flash Region 2 (Intel ME): 00fff000 - 00000fff (unused)*
* Flash Region 3 (GbE): 00fff000 - 00000fff (unused)*
* Flash Region 4 (Platform Data): 00fff000 - 00000fff (unused)*
>From this dump, BIOS region is from 0x200000 to 0x07FFFFF.
So *CONFIG_ROM_SIZE is 8MB *and *CONFIG_CBFS_SIZE is 6MB ( 0x7FFFFF -
0x200000 = 0x5FFFFF)*
Am I correct?
Please correct me, if I am wrong.
