From 232b0ba85e8d19815c0535c7566ece663b3636f6 Mon Sep 17 00:00:00 2001 From: Marco Felsch Date: Mon, 10 May 2021 12:25:21 +0200 Subject: driver: add flag to check if cdev is an mci device We need this during mount() to check if the cdev is an mmc/mci main|user hardware partition device. Later on we add the feature to pass "root=/dev/mmcblkXpN" as kernel command line.
