Subject: [PATCH 12/24] PCI: keystone: Prevent ARM32 specific code to be compiled for ARM64
Date: Mon, 14 Jan 2019 18:54:12 +0530	[thread overview]
Message-ID: <20190114132424.6445-13-kishon@ti.com> (raw)
In-Reply-To: <20190114132424.6445-1-kishon@ti.com>

hook_fault_code is an ARM32 specific API for hooking into data abort.
Since pci-keystone.c will be used for AM65X platforms which is an
ARM64 platform, allow hook_fault_code to be compiled only for ARM32.
