Hi, Oliver:
I have a question abourt ARMv8 CPU's bootloader.
ARMv8 supports: AARCH32 / AARCH64
Take an example:
An ARMv8 SOC, when power up / reset, its default state is : AARCH32
Then, could i still run an old arm uefi bootloader which written by
ARMv7 instruction set?
I will switch ARMv8 SOC to AARCH64 before jumping into linux kernel.
Is it possible?

Best wishes,
