+    $ PATH=$PATH:/usr/powerpc/bin
+    $ CROSS_COMPILE=powerpc-linux-
+    $ export PATH CROSS_COMPILE
+
+    $ powerpc-linux-gcc -v
+    Reading specs from /usr/powerpc/lib/gcc/powerpc-linux/3.4.3/specs

+
+2. Memory Map
+
+2.1. The memory map should look pretty much like this:
+
+     0x0000_0000     0x7fff_ffff     DDR                    2G
+     0x8000_0000     0x9fff_ffff     PCI MEM                512M
+     0xc000_0000     0xdfff_ffff     Rapid IO               512M
+     0xe000_0000     0xe00f_ffff     CCSR                   1M
+     0xe200_0000     0xe2ff_ffff     PCI IO                 16M
+     0xf000_0000     0xf7ff_ffff     SDRAM                  128M
+     0xf800_0000     0xf80f_ffff     BCSR                   1M
+     0xfe00_0000     0xffff_ffff     FLASH (boot bank)      16M

+
+3. Definitions
+
+3.1 Explanation of NEW definitions in:
+
+       include/configs/MPC8349ADS.h
+
+    CONFIG_MPC83xx         MPC83xx family
+    CONFIG_MPC8349         MPC8349 specific
+    CONFIG_MPC8349ADS      MPC8349ADS board specific
+    CONFIG_TSEC_ENET       Use on-chip 10/100/1000 ethernet
+
+
+4. Compilation
+
+    Assuming you're using BASH shell:
+
+       export CROSS_COMPILE=your-cross-compile-prefix
+       cd u-boot
+       make distclean
+       make MPC8349ADS_config
+       make
+
+5. Downloading and Flashing Images
+
+5.0 Download over serial line using Kermit:
+
+       loadb
+       [Drop to kermit:
+           ^\c
+           send <u-boot-bin-image>
+           c
+       ]
+
+
+    Or via tftp:
+
+       tftp 10000 u-boot.bin
+
+5.1 Reflash U-boot Image using U-boot
+
+    tftp 10000 u-boot.bin
+    protect off fe000000 fe09ffff
+    erase fe000000 fe09ffff
+
+    cp.b 10000 fe000000 xxxx
+or
+    cp.b 10000 fe000000 a0000
+
+You might have to supply the correct byte count for 'xxxx' from
+the TFTP.  Maybe a0000 will work too, that corresponds to the
+erased sectors.
