Hello Peter,
    I applied the patch that u had sent, but still its not working.

Here's the output:
# ./flashrom -m "portwell:ppap-2020vl" -E

Calibrating delay loop... OK.
No coreboot table found.
Found chipset "VIA VT8237", enabling flash write... OK.

Unknown vendor:board from coreboot table or -m option: portwell:ppap-2020vl

Found chip "SST SST49LF004A/B" (512 KB) at physical address 0xfff80000.
Erasing flash chip... ERASE FAILED!
ERROR at 0x00000000: Expected=0xff, Read=0x49

I looked at the code and found that in "board_flash_enable" routine, 
"board_match_coreboot_name" fails in "pci_dev_find", and so board is 
returned as NULL.

Please find the attached output of lspci -vnn.

Please guide me further!
