The u-boot-spl.bin pad with ddr firmware conflicts with the CONFIG_MALLOC_F_ADDR area, the ddr firmware will be overwritten by malloc in SPL stage and cause ddr initialization not able to finish. So update the related addresses to fix the issue.

It does allow to boot U-Boot, but 'reset' is broken:

U-Boot proper should use ATF to reset. I think it might be using wdog here.
Also, could you please make sure it can boot a NXP 5.4.3_2.0.0 kernel?
ok, will give a try.
Thanks, Peng.
Thanks
