Boot Linux and pass a flat device tree:

First, U-Boot must be compiled with the appropriate defines. See the section
titled "Linux Kernel Interface" above for a more in depth explanation. The
following is an example of how to start a kernel and pass an updated
flat device tree:

SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock
In order to use PCI-X (only in the first PCI slot. The one with
the RIO connector), you need to set SW1[4] (config) to 1 (off).
Also, configure the board to run PCI at 66 MHz.

3. Flash U-Boot
---------------
The flash range 0xFF800000 to 0xFFFFFFFF can be divided into 2 halves.
It is possible to use either half to boot using u-boot. Switch 5 bit 2
is used for this purpose.
0xFF800000 to 0xFFBFFFFF - 4MB
0xFFC00000 to 0xFFFFFFFF - 4MB
When this bit is 0, U-Boot is at 0xFFF00000.
When this bit is 1, U-Boot is at 0xFFB00000.
Use the above mentioned flash commands to program the other half, and
use switch 5, bit 2 to alternate between the halves. Note: The booting
version of U-Boot will always be at 0xFFF00000.
To Flash U-Boot into the booting bank (0xFFC00000 - 0xFFFFFFFF):
tftp 1000000 u-boot.bin
protect off all
erase fff00000 ffffffff
cp.b 1000000 fff00100 80000
To Flash U-boot into the alternative bank (0xFF800000 - 0xFFBFFFFF):
tftp 1000000 u-boot.bin
erase ffb00000 ffbfffff
cp.b 1000000 ffb00100 80000
4. Memory Map
