At present fdt blob or argument address being passed to kernel is fixed at compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from different media like nand, nor flash are copied to the address pointed by the macro. The problem is, it makes args/fdt blob compulsory to copy which is not required in cases like for NOR Flash. This patch removes this limitation.

I assume you've tested the spl_nor case afterwards, yes? Did this result in some measurable boot time decrease? Thanks!
Yes, I tested it's working on board. Not sure how to measure the impact on boot time.
Cheers, Vikas
