We have tested on the LPC and SPI ROM. The timeout value is OK on our board. You'd better test it on your board.

Hi,
on my Asus M2A-VM, latest flashrom hangs while trying to access SB600 SPI.
flashrom -V Calibrating delay loop... 365M loops per second, 100 myus = 83 us. OK. No coreboot table found. Found chipset "ATI(AMD) SB600", enabling flash write... SPI base address is at 0x0 OK.

--------it hangs here--------------- The mainboard does not have a SPI chip.
