Hello!

When are compiling our recipes with a cross aarch64-gcc compiler, we don't see 
any
"-march=armv8-a -mtune=cortex-a57.cortex-a53" flags in the Makefiles and in the
log.do_compile or log.do_configure.

We require tune-zynqmp.conf in our machine configuration and that means we do
see the aarch64 flags, but not the cortex tune. I didn't find any 
tune-cortexa53, does that mean there is nothing to do for that CPU and that
we should just use the default aarch64 tune?

Are they implicit(the compiler flags) when using an aarch64 cross compiler?

Do I have to create my own tune file for the cortex-a57.cortex-a53?

Maxime,
Thanks
