Announced in October 2011, [3] ARMv8-A represents a fundamental change to the ARM architecture. It adds an optional 64-bit Execution state, named "AArch64", and the associated new "A64" instruction set, in addition to a 32-bit Execution state, "AArch32", supporting the 32-bit "A32" (original 32-bit Arm) and "T32" (Thumb/Thumb-2) instruction sets.
AppliedMicro, using an FPGA, was the first to demo Armv8-A. [159] The first Armv8-A SoC from Samsung is the Exynos 5433 used in the Galaxy Note 4, which features two clusters of four Cortex-A57 and Cortex-A53 cores in a big.LITTLE configuration; but it will run only in AArch32 mode.

And, according to the Arm Architecture Reference Manual Supplement - Armv8, for Armv8-R AArch64 architecture profile, section B1.1: The Armv8-R AArch64 application level programmers’ model differs from the Armv8-A AArch64 profile in the following ways: Armv8-R AArch64 supports only a single Security state, Secure. EL2 is mandatory.
