[coreboot] [PATCH] flahsrom: fix off-by-one error in erase

[Jody McIntyre]

There appears to be an off-by-one error when using flashrom's erase:

# flashrom -E
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "Intel 631xESB/632xESB/3100", enabling flash write... OK.
Found chip "SST SST49LF008A" (1024 KB) at physical address 0xfff00000.
Erasing flash chip... FAILED!
ERROR at 0x00100000: Expected=0xff, Read=0x00
