I want to use nand_spl_load_image in spl.c as it is defined in 
include/nand.h

Unfortunately, it is only defined for CONFIG_TPL_BUILD.
If i remove !CONFIG_SPL_BUILD from second place. this will enable 
nand_load() which i don't want to use.

will it be possible to change all nand_load to nand_spl_load_image() 
permanently.  the only impact I see of "static".
nand_load is static and nand_spl_load_image is not static function 
declaration.
