kernel-fitimage: Allow setting of DTB/DTBO relocation address
Introduce UBOOT_DTB_LOADADDRESS and UBOOT_DTBO_LOADADDRESS so that you can set where U-Boot loads full and overlay DTBs. This is required when using bootm's overlay support to construct the final DTB. Signed-off-by: Alex Kiernan <alex.kiernan@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
