Subject: [PATCH v2 14/29] arm-soc: mvebu: replace open coded VA->PA conversion
Date: Sun,  3 Sep 2017 13:07:42 +0100	[thread overview]
Message-ID: <20170903120757.14968-15-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20170903120757.14968-1-ard.biesheuvel@linaro.org>

This replaces an open coded calculation to obtain the physical
address of a far symbol with a call to the new ldr_l etc macro.
