Re: U-Boot question

In message [ref] you wrote:

I am in the state "while(learning){ .... }" of the U-Boot Porting Guide in

...

The option CFG_SDRAM_BASE is the physical start address of SDRAM.
Okay, I understand that. But it's written _Must_ be 0 here.

Right. Linux on PowerPC expects RAM to start at 0.

How can I do if my SDRAM ( on a MPC860 Board ) start at 04000000 ???

Just define a memory map where your SDRAM starts  at  0.  The  memory
controller is programmed in software, so you can chose any memory map
you like.

PS : Sorry to don't post to the U-Boot mailing list but I have a failure
notice each time
I try to post on it. (550-Envelope sender verification failed)

Then fix this!
