Subject: [PATCH 1/3] iommu/io-pgtable-arm: Prepare for modularization
Date: Fri, 18 Dec 2020 00:38:40 -0800 [thread overview]
Message-ID: <1608280722-19841-2-git-send-email-isaacm@codeaurora.org> (raw)
In-Reply-To: <1608280722-19841-1-git-send-email-isaacm@codeaurora.org>
The io-pgtable-arm and io-pgtable-arm-v7s source files will
be compiled as separate modules, along with the io-pgtable
source. Export the symbols for the io-pgtable init function
structures for the io-pgtable module to use.
Signed-off-by: Isaac J. Manjarres <isaacm@codeaurora.org>
