Subject: [PATCH 7/7] iommu/io-pgtable-arm: Allow building modular io-pgtable formats
Date: Mon, 28 Dec 2020 17:49:01 -0800	[thread overview]
Message-ID: <1609206541-14562-8-git-send-email-isaacm@codeaurora.org> (raw)
In-Reply-To: <1609206541-14562-1-git-send-email-isaacm@codeaurora.org>

Now that everything is in place for modular io-pgtable formats,
allow the ARM LPAE and ARMV7S io-pgtable formats to be built
as modules, and allow the io-pgtable framework to be enabled,
without having to explicitly enable an io-pgtable format.
