From f6432ecea666eb4b7cbe48bde804fb886f0a8cae Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 11 Sep 2019 14:33:44 -0300 Subject: [PATCH] pico-imx6ul: Provide a way to escape the Falcon mode When CONFIG_SPL_OS_BOOT is selected, it is still convenient to be able to escape from Falcon mode and boot to U-Boot proper. Add a mechanism that allows booting in U-Boot proper when the key 'c' is entered on console at boot time.
