Hi, Ryan:

Thanks for your reply!

Because current ARMv8 SOC usually has two system software configuration:

1. AARCH64 Kernel + AARCH32 Android

2. AARCH32 Kernel + AARCH32 Android

Some experts claims that:

Because AARCH64 Linux kernel is not mature until now, and Android still not support AARCH64.

Then “AARCH32 Kernel + AARCH32 Android” is prefer than “AARCH64 Kernel + AARCH32 Android”

So, I thought:

If adopting configuration 2 “AARCH32 Kernel + AARCH32 Android”, then maybe AARCH32 UEFI is needed.

Best wishes,
