Subject: [PATCH v3 2/3] arm: dts: am335x-sancloud-bbe-lite: UEFI SPI export
Date: Wed, 21 Sep 2022 17:06:27 +0100 [thread overview]
Message-ID: <20220921160628.4166966-3-paul.barker@sancloud.com> (raw)
In-Reply-To: <20220921160628.4166966-1-paul.barker@sancloud.com>
Add properties to the Authenta SPI flash device node to enable access by
a UEFI application using a fixed GUID. Also specify that this device is
JEDEC compatible so that it is correctly initialized when running
`sf probe`.
