    sbc8548: reclaim wasted sector in boot flash · dd9ca98f
    Paul Gortmaker authored
    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.
