Subject: [PATCH 1/1] arm64: dts: meson: g12b: odroid-n2: Assign a fixed index to mmc devices
Date: Thu, 28 Jan 2021 00:08:52 +0100 [thread overview]
Message-ID: <20210127230852.66686-1-alexander.stein@mailbox.org> (raw)
Recently introduced async probe on mmc devices can shuffle block IDs.
Pin them to fixed values to ease booting in environments where UUIDs
are not practical. Use newly introduced aliases for mmcblk devices from [1].

I was wondering which order I should use. Depending in your booting
medium (SD card or eMMC) you 'want' one or the other as mmc0.
In the end I ordered them according to the names.
