arm64: versal-net: Enable remaking ELF from bin
U-Boot is composing u-boot.bin from u-boot-nodtb.bin with appended
dts/dt.dtb. It means U-Boot doesn't have DTB inside. When REMAKE_ELF is
enabled make will also create u-boot.elf which is recreated from
u-boot.bin. Below is build output for mini configuration how ELF is
recreated.
cat arch/arm/dts/versal-net-mini.dtb > dts/dt.dtb
cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
cp dts/dt.dtb u-boot.dtb
cp u-boot-dtb.bin u-boot.bin
aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64
u-boot.bin u-boot-elf.o
aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf -EL -T u-boot-elf.lds
--defsym="_start"=0xBBF00000 -Ttext=0xBBF00000
It is useful to have u-boot.elf present because Xilinx XSDB debugger can
load ELF file and user doesn't need to specify loading address for
u-boot.bin.
