Hi all,
I've noticed a difference from u-boot 1.2.0 and the Freescale 85xx git repo - particularly PEX and the mpc8548cds. Looking at the CDS schematic I believe that's PCI express. I noticed there is now a TLB entry for PEX - unlike previous versions:
* 0xe300_0000 0xe3ff_ffff PEX IO 16M
I asked about PCI Express for 85xx on the list recently and was informed "You do not need to specify TLB/LAW for PCI-X. it uses the same memory map as PCI1."
What is the PEX TLB entry for? The mpc8548cds docs in the git repo haven't been updated yet.
I have a 8548 custom board - similar somewhat to the mpc8548cds and I'm using that as a reference - that arrives right around the August 17th code freeze. I'm planning on using the git repo code for my developement rather than the stable release code of 1.2.0. Is the repo code recommended over 1.2.0 ? It probably is but I thought I'd ask.
Thanks, Robert
