Following patch extends the ROM decoding to last 1MB, allowing to use larger flashes such as SST49LF080A: 1024K x8 (8 Mbit)
Tested on my system, the flash is found and if I use coreboot in second half it works too.

Tested on ASUS A8V-E Deluxe with a 1MB coreboot image (modified ROM_SIZE in targets/.../Config.lb) using a SST49LF080A chip. Boots fine.

You mean "LPC" or maybe "Bus Control and Power Management" as per datasheet?
- dev = pci_locate_device(PCI_ID(PCI_VENDOR_ID_VIA,
PCI_DEVICE_ID_VIA_VT8237R_LPC), 0);- if (dev == PCI_DEV_INVALID)

Missing full stop and space before "*/".
