Subject: [PATCH 14/15] arm-soc: shmobile: replace open coded VA->PA calculation
Date: Sat, 5 Aug 2017 21:52:21 +0100 [thread overview]
Message-ID: <20170805205222.19868-15-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20170805205222.19868-1-ard.biesheuvel@linaro.org>
This replaces a couple of open coded calculations to obtain the
physical address of a far symbol with calls to the new adr_l etc
macros.
