support 4-byte address format for VARIABLE_SIZE dummy flash device
This patch adds a support of 4-byte address format for VARIABLE_SIZE
dummy flash device, so that it can emulate an flash size larger than
16 MBytes.
- assigned a feature bits FEATURE_4BA to VARIABLE_SIZE flash config.
- added codes handling two commands, JEDEC_READ_4BA and
JEDEC_BYTE_PROGRAM_4BA.
- changed blockeraser to use Chip-Erase command so that it can be
free from flash address byte format.
TEST=ran the command line below:
$ flashrom -p dummy:image=${TMP_FILE},size=33554432, \
emulate=VARIABLE_SIZE -w ${IMG_32MB} -V -f
$ flashrom -p dummy:image=${TMP_FILE},size=16777216, \
emulate=VARIABLE_SIZE -w ${IMG_16MB} -V -f
$ flashrom -p dummy:image=${TMP_FILE},size=8388608, \
emulate=VARIABLE_SIZE -w ${IMG_8MB} -V -f
