Subject: [PATCH v10 15/32] ARM: vGICv3: re-use vgic_reg64_check_access
Date: Fri, 26 May 2017 18:35:23 +0100 [thread overview]
Message-ID: <20170526173540.10066-16-andre.przywara@arm.com> (raw)
In-Reply-To: <20170526173540.10066-1-andre.przywara@arm.com>
vgic_reg64_check_access() checks for a valid access width of a 64-bit
MMIO register, which is useful beyond the current GICv3 emulation only.
Move this function to the vgic-emul.h to be easily reusable.
