For one of our devices (which uses ARM A53 Core with GICv2) we need to configure one of the interrupt sources as FIQ at EL1.So is there any support for doing such a thing preferably in any of the branches of linux kernel.
Thanks Vincent, even i had the same idea but just wanted to get it verified at arm community.
fyi.. ATF(EL3) supports it (but just that we needed it on EL1)
