[U-Boot-Users] PCI access memory space

I'm using on my custom board (PPC 440GX) an ATI M6-C16H Mobility Radeon
video card. I work with U-boot 1.1.2. 
I can access the configuration space of ATI with the functions:
pci_read_config_dword(..) and pci_write_config_dword(.)

Now I have to access the memory space of the ATI. I use the functions: 
	readl(.) and writel(..)

But when I start u-boot, it hangs. I can not access the memory base address
of the ATI.

Can someone please give me information how U-Boot handles with PCI devices
when accessing the memory space.        

Thanks for any help,
