Hello Dirk,
I have made only single change - I recompile ATF to leave CPU in EL2
mode and reflash it.
Yes, this is what I meant with 'modifying firmware' ;)
You are loading Xen with U-Boot running in EL2, then?
With this modification, do all other use cases still work? E.g. load and
boot U-Boot and native Linux kernel without Xen?
Yes, when Linux is booting from EL2, it will drop to EL1 (see
el2_setup). As Andre mentioned on the previous thread, U-boot is running
at EL2 on various board (e.g pine64, juno).
Modifying the firmware was the right way to go as there is no solution
go boot at EL2 from EL1.
