> These newer ARM processors support 32-bit code at EL0 only (userspace). Even that is being phased out, starting from 2021 ARMs reference cores mostly dropped 32-bit support, with the Cortex-X2 big cores and Cortex-A510 small cores being 64-bit only, and only the medium Cortex-A710 cores retaining the ability to run 32-bit code in userspace. With the next generation the medium cores lost 32-bit support, but the small cores gained 32-bit support again, so the chips can barely still run 32-bit code but it's relegated to only running on the least performant cores. I'm sure they'll drop it altogether as soon as they think the market will accept it.
