Running armv7 binaries on armv8

Hi Experts,

I have binaries built for armv7 architecture, without rebuilding binaries can I run on armv8?. I think its possible, but wanted confirm is there any limitation?

Thanks,

Veeranna

If EL1 is using AArch64, to get to EL0 you need to perform an exception return. The Execution state of EL0 is set by the SPSR_EL1 value when you perform the exception return. If SPSR_EL1[4:0] ==b00000, EL0 uses AArch64. If SPSR_EL1[4:0]==b10000, EL0 uses AArch32
