Did you mean this? https://community.freescale.com/docs/DOC-95578

That surely looks very hacky.

I'm currently more-or-less stumble around like a blind one in order to
get FIQ running on i.MX6. Seems that mxc_set_irq_fiq() is a NOP on
i.MX6, because AFAIK this function is only supported by chips with an
TZIC or an AVIC.
