[Qemu-devel] [PATCH 04/15] hw/intc/arm_gic: Add ns_access() function

[Fabian Aggeler]

Security Extensions for GICv1 and GICv2 use register banking
to provide transparent access to seperate Secure and Non-secure
copies of GIC configuration registers. This function will later
be replaced by code determining the security state of a read/write
access to a register.
