[PATCH v2 2/3] arm64: Bail out PIE builds early if load address is not 4K aligned

2020-09-04 Thread Edgar E. Iglesias
From: "Edgar E. Iglesias" 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. Tested-by: Michal Simek Suggested-by: André Przywara Signed-off-by: Edgar E. Iglesias --- arch/arm/cpu/armv8/start.S | 17 +
