/*
* The EV-64260-BP port is the result of hard work from many people from
* many companies. In particular, employees of Marvell/Galileo, Mission
* Critical Linux, Xyterra, and MontaVista Software were heavily involved.
*
* Note: I have not been able to get *all* PCI slots to work reliably
* at 66 MHz. I recommend setting jumpers J15 & J16 to short pins 1&2
* so that 33 MHz is used. --MAG
* Note: The 750CXe and 7450 are not stable with a 125MHz or 133MHz TCLK/SYSCLK.
* At 100MHz, they are solid.
