Hi,
I have not yet factored out the general elements of SPL direct boot. ATM i don't have the time - so if someone wants to take it :)
If not this will have to wait, maybe until next year.
Regards Simon

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!
Changes in V10:
- spl_start_uboot replaces spl_uboot_key and is defined weak
- if the linux image is not found a normal u-boot is started
- some minor changes
based on:
- Prep subcommand patch for arm
Please test this patch - there have been major changes!
