I am new to the Xilinx hardware. We are trying to implement a second stage bootloader[EL3] for
handling some specific initialization before starting uboot on cortex-a53.
- Can we boot linux without ARM Trusted Firmware? If yes what are the minimal configuration I need to take care
to start uboot from our second stage bootloader?
- It would be very helpful if I could get some references to application notes or manuals
Setup I am using:
ZCU102 development kit

Thanks for your time!
It would have been better if we could bypass ATF.
I am not sure if I can perform my functions in Uboot which would be in EL2/EL1. I need to access few trust zone registers for security configuration before loading the low priority software stack.
However using a custom FSBL could be an option. Similar to that, using my code as secondary boot loader(at EL3) would keep the vendor provided FSBL untouched.
