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
