Subject: [edk2-devel] [PATCH 1/2] DynamicTablesPkg: AML Code generation for I/O ranges
Date: Mon, 11 Sep 2023 23:48:57 +0000 [thread overview]
Message-ID: <64a84c1fedd66114f46ddd5d47ff922d68169d4c.1694475927.git.jbrasen@nvidia.com> (raw)
In-Reply-To: <cover.1694475927.git.jbrasen@nvidia.com>
From: Vidya Sagar <vidyas@nvidia.com>
Add helper functions to generate AML Resource Data describing I/O
ranges of four words long. API AmlCodeGenRdQWordIo () is exposed.
