From ceeefcaf55120c371891ea37cc3db28d8391386f Mon Sep 17 00:00:00 2001 From: Ye Li Date: Wed, 10 Oct 2018 01:25:18 -0700 Subject: MLK-19869-2 imx6: fix mmc_get_boot_dev issue when booting from USB The mmc_get_boot_dev reads from SRC SBMR register. When booting with USB serial download, this function does not return correctly. Because SBMR won't reflect the USB boot. The patch adds USB boot checking to this function to fix the issue.
