Subject: [PATCH] irqchip/gic-v3: Remove the unused register definition
Date:   Tue, 30 Jun 2020 21:41:26 +0800
Message-ID: <20200630134126.880-1-yuzenghui@huawei.com>
MIME-Version: 1.0

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As per the GICv3 specification, GIC{D,R}_SEIR are not assigned and the
locations (0x0068) are actually Reserved. GICR_MOV{LPI,ALL}R are two IMP
DEF registers and might be defined by some specific micro-architecture,
Linux doesn't use them.

As they're not used anywhere in the kernel, just drop all of them.
