Enable CONFIG_OF_BOAD to support delivery dtb to u-boot at run time instead of embedded. There are two methods to delivery dtb. 1 Pass from loader: When u-boot boot from RAM, gdb or loader can pass dtb via a2 to u-boot dynamically. Of course gdb or loader shall be in charge of dtb delivery. 2 Configure CONFIG_SYS_FDT_BASE: It can be configured as RAM or ROM base statically, no mater u-boot boot from RAM or ROM. If it was configured as ROM base, dtb can be burned into ROM(spi flash) by spi driver. Meanwhile remove CONFIG_SKIP_LOWLEVEL_INIT which is useless in nx25-ae250 configuration.
