We have an MPC8247 based board on which we have uboot-1.1.2.
I am able to read the PCI configuration space through uboot.
I am trying to access the PCI memory mapped registers of a broadcom device
I have configured the base address and 'memory access enable' on the  
broadcom device through its configuration space registers. I have not  
configured interrupts for the device.
When I try to read a register from the base address offset, the system  
However a write to only some registers casues a hang.
Any idea what the problem could be?
