This is another alternative for the RFC: https://lkml.org/lkml/2019/3/27/545 This new workaround proposal is a little bit more hacky but more contained since everything is done within the irq-imx-gpcv2 driver. Basically, it 'hijacks' the registered gic_raise_softirq __smp_cross_call handler and registers instead a wrapper which calls in the 'hijacked' handler, after that calling into EL3 which will take care of the actual wake up. This time, instead of expanding the PSCI ABI, we use a new vendor SIP. I also have the patches ready for TF-A but I'll hold on to them until I see if this has a chance of getting in.
