From b446ce2977e12eba8de6d04d6c608e1b1a766c9f Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 11 Sep 2019 14:30:28 -0300 Subject: [PATCH] pico-imx7d: 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.
