Subject: [PATCH 43/43] MdeModulePkg/BmBoot: skip secondary eMMC entries
Date: Mon, 31 Jan 2022 21:00:54 +0000 [thread overview]
Message-ID: <d379831c0a96c87795cba419c09e639db145a307.1643662841.git.sean@starlabs.systems> (raw)
In-Reply-To: <9dd14fc91c174eae87fd122c7ac70073a363527f.1643662841.git.sean@starlabs.systems>
Internal eMMC devices often show multiple entries, so skip
any after the initial entry.
