From 6b165ab2b7b1dc89357afbe86c1977addf5aed3b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 5 Jul 2021 16:32:58 -0600 Subject: [PATCH] sandbox: mmc: Support fixed MMC devices Add support for reading devicetree flags for MMC devices. With this we can distinguish between fixed and removable drives. Note that this information is only available when the device is probed, not when it is bound, since it is read in the of_to_plat() method. This could be changed if needed later.
