  31 2. Memory Map
  32
  33 2.1. The memory map should look pretty much like this:
  34
  35      0x0000_0000     0x7fff_ffff     DDR                     2G
  36      0x8000_0000     0x9fff_ffff     PCI MEM                 512M
  37      0xc000_0000     0xdfff_ffff     Rapid IO                512M
  38      0xe000_0000     0xe00f_ffff     CCSR                    1M
  39      0xe200_0000     0xe2ff_ffff     PCI IO                  16M
  40      0xf000_0000     0xf7ff_ffff     SDRAM                   128M
  41      0xf800_0000     0xf80f_ffff     BCSR                    1M
  42      0xfe00_0000     0xffff_ffff     FLASH (boot bank)       16M

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