Jan,
I was able to get almost everything working on AM572 IDK, but had to move to a
new compiler:
arm-linux-gnueabihf-gcc (GNU Toolchain for the A-profile Architecture
8.3-2019.03 (arm-rel-8.36)) 8.3.0
Copyright (C) 2018 Free Software Foundation, Inc.

Now I'm getting errors:

I guess the new toolchain requires to pass additional "arch_extension" options
to assembler.
If I add asm(".arch_extension sec\n"); before each asm line in the smccc.c that works, but I'm
getting errors at other places missing "virt" extension.
I don't believe I need to edit each source file, It must be a way to add the required options to
makefiles.
Do you know how to fix that issue?
Thanks,
-Vitaly
