  29 2. Memory Map
  30
  31 2.1. The memory map should look pretty much like this:
  32
  33      0x0000_0000     0x7fff_ffff     DDR                     2G
  34      0x8000_0000     0x9fff_ffff     PCI MEM                 512M
  35      0xc000_0000     0xdfff_ffff     Rapid IO                512M
  36      0xe000_0000     0xe00f_ffff     CCSR                    1M
  37      0xe200_0000     0xe2ff_ffff     PCI IO                  16M
  38      0xf000_0000     0xf7ff_ffff     SDRAM                   128M
  39      0xf800_0000     0xf80f_ffff     BCSR                    1M
  40      0xfe00_0000     0xffff_ffff     FLASH (boot bank)       16M

  45 3.1 Explanation of NEW definitions in:
  46
  47         include/configs/MPC8349ADS.h
  48
  49     CONFIG_MPC83xx          MPC83xx family
  50     CONFIG_MPC8349          MPC8349 specific
  51     CONFIG_MPC8349ADS       MPC8349ADS board specific
  52     CONFIG_TSEC_ENET        Use on-chip 10/100/1000 ethernet
  53
  54
  55 4. Compilation
  56
  57     Assuming you're using BASH shell:
  58
  59         export CROSS_COMPILE=your-cross-compile-prefix
  60         cd u-boot
  61         make distclean
  62         make MPC8349ADS_config
  63         make
  64
  65 5. Downloading and Flashing Images
  66
  67 5.0 Download over serial line using Kermit:
  68
  69         loadb
  70         [Drop to kermit:
  71             ^\c
  72             send <u-boot-bin-image>
  73             c
  74         ]
  75
  76
  77     Or via tftp:
  78
  79         tftp 10000 u-boot.bin
  80
  81 5.1 Reflash U-boot Image using U-boot
  82
  83     tftp 10000 u-boot.bin
  84     protect off fe000000 fe09ffff
  85     erase fe000000 fe09ffff
  86
  87     cp.b 10000 fe000000 xxxx
  88 or
  89     cp.b 10000 fe000000 a0000
  90
  91 You might have to supply the correct byte count for 'xxxx' from
  92 the TFTP.  Maybe a0000 will work too, that corresponds to the
  93 erased sectors.
