Uboot-Raspberry3b-Bare metal code

[Little Tree]

Hi,
I have written (copied from here
https://github.com/bztsrc/raspi3-tutorial/tree/master/0F_executionlevel)  a
small bare metal program to switch exception level from EL2 to EL1 in
Raspberry Pi 3B. The program is linked to load at the address 0x80000. The
stripped version of the ELF is directly loaded through the "config.txt"
file (without U-Boot) and it works. It is able to access the mini UART and
print a message from EL1.

Now I have modified the same program to load at the address (0x1000000) by
modifying the linker (link.ld) file. Stripped it using objcopy. started the
board with U-Boot. From U-boot prompt loaded the binary to the address
0x1000000 (using tftpboot). Then initiated the execution using go 0x1000000.

This ends up in a board reset with the following error.

U-Boot> go 0x1000000

Resetting CPU ...

I built U-Boot with default configuration for raspberry-pi3 and arm64. My
program crashed on both of them. This error log is from BCM2835-arm64
U-Boot build.

Is there any specific requirement for U-Boot which should be met by the
bare metal program?
I have been struggling with this for quite some time. Any help/hint is (to
some documentation at lleast) greatly appreciated.

Thanks a lot,
  Little
