Hi all,

I'm preparing u-boot for my custom MPC8548E board which is arriving soon. Here's my memory map:

0x0000_0000 0x7fff_ffff DDR 2G 0x8000_0000 0x9fff_ffff PCI1 MEM 512M 0xa000_0000 0xbfff_ffff PCI2 MEM 512M 0xe000_0000 0xe000_ffff CCSR 1M 0xe200_0000 0xe20f_ffff PCI1 IO 1M 0xe210_0000 0xe21f_ffff PCI2 IO 1M 0xf800_0000 0xffff_ffff FLASH (boot bank) 128M

We also have a PCI-X . Are TLB and LAW entries required for PCI-X ?

You do not need to specify TLB/LAW for PCI-X. it uses the same memory map as PCI1. Check the manual.

I've seen some PCI-X stuff in the u-boot distro CPU and Driver section, but nothing much in the board section. Any clarification on what, if anything, is needed for u-boot to setup on a custom board with PCI-X would be appreciated.

PCI-X should use the same stuff as PCI1. Roy
