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