I tried changing the boot rom size to 2MB.
But with no effect

coreboot.rom: 2048 kB, bootblocksize 944, romsize 2097152, offset 0x0
alignment: 64 bytes, architecture: x86

Name                           Offset     Type         Size
cmos_layout.bin                0x0        cmos_layout  1160
fallback/romstage              0x4c0      stage        17960
fallback/ramstage              0x4b40     stage        56190
config                         0x12700    raw          2990
revision                       0x13300    raw          692
(empty)                        0x13600    null         2016728
    HOSTCC     cbfstool/rmodtool.o

Thanks
Ajoy
