Adds direct Linux boot to SPL. It implements a spl export command to save ATAGS or FDT to NAND flash. The kernel image has to be in place for this!

Hi Simon,
I am testing your patches (V9) - the kernel image is not corrupted anynmore due to the ECC, but I am not able to boot successfully the kernel. I am testing now with a second hardware (twister, I have recently posted the patches for this board, also OMAP3) to have a comparison with the beagleboard.
The kernel starts but it stops very soon, I think after the machine-id check and it seems it cannot poarse correctly the tags. However, the parameters exported by "spl export" are correct and I have not found any difference with the "bootm" command under U-boot.
I am starting to debug the kernel to get some more infos, but do you have some hints ? How do you test it ?
Best regards, Stefano Babic
Hi Stefano,
great that someone has a closer look on this!
The only problem i had was a wrong machine id (The one to use is defined in the board config file).
So I didn't do any debugging in the kernel besides from activating early printk.
Regards Simon
