New Revision: 3148

Modified:
   trunk/coreboot-v2/src/mainboard/asus/a8v-e_se/cache_as_ram_auto.c
   trunk/coreboot-v2/src/southbridge/via/vt8237r/vt8237r_early_smbus.c
Log:
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.
