As far as I can see: it seems to me that the config.mk avoid that the
u-boot image overwrites the SPL code, making then impossible to boot.
Is it really copied into CONFIG_SYS_NAND_U_BOOT_DST ?

However, I see that CONFIG_SYS_TEXT_BASE_SPL is set in some boards, and
looks liketo be the correct mechanims to be used to set TEXT_BASE for
the SPL binary.
