sbc8548: reclaim wasted sector in boot flash
By nature of being based off the MPC8548CDS board, this
board inherited an ENV_SIZE setting of 256k. But since
it has a smaller flash device (8MB soldered on), it has
a native sector size of 128k, and hence the ENV_SIZE was
causing 2 sectors to be used for the environment.
By removing the unused sector, we can push TEXT_BASE up
closer to the end of address space and reclaim that
sector for any other application. This also fixes the
mismatch between TEXT_BASE and MONITOR_LEN reported by
Kumar earlier.
Since this board also supports the ability to boot off
the 64MB SODIMM flash, this change is forward looking
with that in mind; i.e. the settings for MONITOR_LEN
and ENV_SIZE will work when the 512k sectors of the
SODIMM flash are used for alternate boot in the future.
