+0. Toolchain / Building
+
+ $ 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
+ Configured with: ../configure --prefix=/usr/powerpc
+ --exec-prefix=/usr/powerpc --target=powerpc-linux --enable-shared

+1. Board Switches and Jumpers
+
+
+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.
+
