[U-Boot] EFI Stub compilation errors

[Nicolae Rosia]

Hello,

I'm trying to build U-Boot as an UEFI Payload, head
4ed6ed3c27a069a00c8a557d606a05276cc4653e, branch master.
I did the following:
make qemu-x86_defconfig
make menuconfig
Enable the following:
CONFIG_EFI=y
EFI_STUB=y
EFI_STUB_64BIT=y
make

I gets lots of warnings ([0]) and the following error:
/home/user/workspace/u-boot/lib/efi/efi_stub.c:357: undefined
reference to `_binary_u_boot_dtb_bin_start'
/home/user/workspace/u-boot/lib/efi/efi_stub.c:357: undefined
reference to `_binary_u_boot_dtb_bin_end'

Any idea what I'm doing wrong?

Best regards,
Nicolae
