PIE requires a 4K aligned load address. If this is not met, trap the startup sequence in a WFI loop rather than running into obscure failures.

diff --git a/arch/arm/cpu/armv8/start.S b/arch/arm/cpu/armv8/start.S #if CONFIG_POSITION_INDEPENDENT

• /* Verify that we're 4K aligned. */

Similar to the comment on the previous patch: I believe the code that implements this check should be outside the #if check, since it's always needed.
