[U-Boot-Users] Patches for 85xx question

Hi all, I'd like to submit patches for our project 'atum' (Tuna in Brazilian portuguese, its a custom to name projects after fishes) for inclusion into u-boot. Its a 8548 based board. Should I base patches off of u-boot 1.3.1 , http://opensource.freescale.com/pub/scm/u-boot-85xx.git , or some other git repo?
BTW, thanks for this excellent community and all the help we received so far, Robert

So does this mean you've managed to get Linux up and running, no memory issues, etc? Congratulations!
Cheers, Dave
Hey thanks, what a long strange trip its been ;-) .
For the memory issues, we found a memory chip (Micro 533MHZ) that works 95% of the time, and the hardware guys are working with Freescale support for our second revision, and in fact have already improved things considerably on other chips. That's good enough to continue the project ;-) .
The PCI issues were resolved also by hardware, via using "Asynchronous mode" instead of "Synchronous mode", thereby routing CLKOUT to PCI1_CLK. See the "4.4.3.17 PCI Clock Selection" section if interested.
So the latest 2.6.24RCx kernel's now booting, and all that's left is a few driver issues. That and submitting patches ;-) .
Cheers, Robert

Hi Robert,

Sounds more like the trip you should have expected. That'll teach you for being optimistic, eh I get burned for being that way too - an engineering trait I guess.

Feel free to provide details on your solutions.
The Freescale design documents are sparce in some places, incorrect in others. AN2931 which contains the design recommendations for boards based on the 83xx series processor has been revised multiple times since I started work on my board. And even now, there are other valid ways to implement parts of the design.
The PCI issues were resolved also by hardware, via using "Asynchronous mode" instead of "Synchronous mode", thereby routing CLKOUT to PCI1_CLK. See the "4.4.3.17 PCI Clock Selection" section if interested.
So you have clocking issues?

Glad to hear your 'Tuna' can swim. Sure beats being stuffed into a tin can :)
Cheers, Dave

Use the u-boot-85xx.git tree on denx.de.
