[U-Boot-Users] [PATCH] One more patch for the sequoia

I've tried again. (attched this time so that OUTLOOK does not mess up
the formating.)

Explanation of attached patch:

Because the Sequoia board does not boot with an EBC faster than 66MHz, 
the clock divider are changed after the initial boot process. 

This allows for maximum clocking speeds  to be achieved on newer boards.
Sequoia boards with 666.66 MHz processors require that the EBC divider 
be set to 3 in order to start the initial boot process at a slower EBC 
speed. After the initial boot process, the divider can be set back to 2,

which will cause the boards to run at 83.333MHz. This is backward 
compatible with boards with 533.33 MHz processors, as these boards will 
already be set with an EBC divider of 2.
