One way that I have used/tested before was to create a tee.elf version
using something like:
$ aarch64-linux-gnu-objcopy -B aarch64 -I binary -O elf64-littleaarch64
xxx_bl32_vX.YZ.bin bl32.o
$ aarch64-linux-gnu-ld bl32.o -T tee.ld -o tee.elf
tee.ld:
----
ENTRY(_binary_bl32_bin_start);
SECTIONS
{
. = 0x08400000;
.data : {
*(.data)
}
}
----
And then make with TEE=tee.elf, however keep in mind that U-Boot may not
treat the memory region used by OP-TEE properly for aarch64.
