How to only flash BIOS region on braswell.

[Sampson Lee]

Hello,

I have a question about flash BIOS region on braswell.

I use W25Q64.V(8M),the layout is TXE(3M/address:0~0x300000)+BIOS(coreboot
2M/address:0x600000~0x800000).

If I use command "flashrom -p internal -w xxx.bin",it will flash all
data(8M).
But I want to only flash BIOS region.
Should i use which command to flash?

Thanks.
Sampson.
