Hi experts,
I am trying to boot the linux by my bootloader which is running on EL3 level.(switch to EL1 when I jump to the kernel)
The trustzone is not necessay for me, so I don't want to use it.
However, I'm comfused if the arm-trusted-firmware is needed?
Some boards like Juno and Hikey have used the arm-trusted-firmware .
Regards,
Jorney
