This adds NAND boot support for LS2085AQDS, using SPL framework.
To form a NAND image, append u-boot-with-spl.bin after a proper nand boot RCW and flash to the beginning of NAND.
Do we want to do it this way, or should we keep the RCW in a separate block?
I would like to see RCW in a separated block.
What constitutes a "proper nand boot RCW" (those were not my words)? There are details in this patch regarding offsets that need to match details in the PBI (which is more than just RCW).
It is not your original words. Yours was "To form a NAND image, append u-boot-with-spl.bin after PBL_0x3_0x07_1333_nand.bin and flash to the beginning of NAND.". I try to make the message generic. A proper nand boot RCW means the RCW should contains PBI commands to set bootloc and block copy the image. Since RCW is not in the scope of u-boot, I cannot refer to any specific file.
Do you want to include an RCW file into u-boot, like those for powerpc boards?
It would also be nice to sort out loading the environment during SPL.
That can be an additional patch when you have it.
