It is possible to run aarch32 linux on aarch64 hardware, but
with the ARM64 dependency, we are not able to build those drivers
for ARM32.
Select ARM_GIC_V3 for i.MX8M is to enable the gic-v3 driver for i.MX8M
I did a basic boot test on i.MX8MM EVK board. A few ATF changes
to make psci smp work still needed.

Moving to support aarch32 mode on aarch64 hardware, need to drop
the dependency on ARM64 to make the driver could be selected for
ARM32.

Select ARM_GIC_V3, then it is able to use gic v3 driver in aarch32
mode linux on aarch64 hardware. For aarch64 mode, it not hurts
to select ARM_GIC_V3.

If you say yes here you get support for the NXP i.MX8M family
support, it will provide the SoC info like SoC family,

It would seem sensible to also drop the dependency on the 'default'

If drop default, we need enable this config option in ARM64 defconfig,
I would leave it as is for now.
Thanks,
Peng.

I meant making it 'default ARCH_MXC' so it gets enabled for both
32-bit and 64-bit i.MX configurations, not just 64-bit.

Understand. I'll drop ARM64 and post v2 with your A-b.
