From b8aa463e9ba96e66fc24e0d7cd0e07e9bc7bc839 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 24 Apr 2022 23:31:14 -0600 Subject: bootstd: mmc: Add a bootdev driver Add a bootdev driver for MMC. It mostly just calls the bootdev helper function. Add a function to obtain the block device for an MMC controller. Fix up the comment for mmc_get_blk_desc() while we are here.
