EHF + OPTEE on ARM64

Hi,

In bl31/ehf.c, there are following two lines, per my understanding, when cpu is in secure world, the non-secure interrupt as FIQ(GICv3) will be directly catched by EL3, not S-EL1 /* Route EL3 interrupts when in Secure and Non-secure. */ set_interrupt_rm_flag(flags, NON_SECURE); set_interrupt_rm_flag(flags, SECURE);

So this will conflict with OP-TEE, because OP-TEE needs catch NS-interrupt as FIQ in S-EL1 world.

Am I understand correct?

Any ideas how we could address this to make EHF + OPTEE run together?

Thanks Peng.
