  312. Memory Map
  32
  332.1. 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

  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
  574. 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
  675. Downloading and Flashing Images
  68
  695.0 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
  835.1 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
  90or
  91    cp.b 10000 fe000000 a0000
  92
  93You might have to supply the correct byte count for 'xxxx' from
  94the TFTP.  Maybe a0000 will work too, that corresponds to the
  95erased sectors.
