From 15b1d44fd2c56e201eeb8276b6359e6c21517ad0 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Fri, 17 May 2019 02:41:03 -0700 Subject: [PATCH] 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.
