Hi Nico,

I have taken the Flash Region's dump of my vendor BIOS using Ifdtool (which is copied below),

FLREG0: 0x000f0000

Flash Region 0 (Flash Descriptor): 00000000 - 0000ffff

FLREG1: 0x07ff0200

Flash Region 1 (BIOS): 00200000 - 007fffff

FLREG2: 0x00000fff

Flash Region 2 (Intel ME): 00fff000 - 00000fff (unused)

FLREG3: 0x00000fff

Flash Region 3 (GbE): 00fff000 - 00000fff (unused)

FLREG4: 0x00000fff

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.

Thanks,

Dhanasekar

That should work fine.

crossgcc is only needed once.
