Hello Alex,
I am interested in seeing this work merged into U-Boot. Will you have the time to fix the issues pointed out by Reinhard Meyer and post an updated version, or would you accept if somebody else takes over your patch set and posts an updated version ?
Thanks,
Thomas

This patch set fixes the at91sam9mg45ek build for my set up. I have only been able to test this patch on my own NAND booting at91sam9m10g45ek. Dataflash and norflash are untested. Anyway, this is a rough approximation of a patch; I would need more input from people with nor-flash, working at91bootstrapers, dataflash, etc before I can get truely generic working at91sam9m10g45ek board support.
Also, some notes:
I wrote my own boot strapper because I could not find a working boot strapper. The boot strappers I found on the web either had their own issues or did not enable the second bank of RAM. Thus I wrote my own that works and enables the second bank of RAM. The patch here expects that the second bank works. If you are using a working at91bootstrapper or the like, I don't think that should cause this u-boot patch to not work; just set the number of banks back to 1 in the config file.
If I am not alone in having trouble with the existing at91bootstrap projects, maybe we could merge my bootstrapper into (or the preexisting at91bootstrapper proejcts) into the NAND SPL (for NAND booting boards) section of U-Boot?
