V2:
- Removed unecessary NAND_PAGE_SIZE in ls1043a_common.h.
- Fixed "select SUPPORT_SPL" in arch/arm/Kconfig.
- Used CONFIG_FSL_IFC instead of SPL_NAND_SUPPORT for init_early_memctl_regs()
- Replaced ns_access.h with fsl_csu.h.
V3:
- No change.
V4:
- Add enable_layerscape_ns_access() in fsl-layerscape/spl.c
