From 77ecf95f22dc5cb0a9709805dd22555007d60b34 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 17 Sep 2019 22:04:57 -0300 Subject: pico-imx6: Add Falcon mode Add Falcon mode support, which allows the SPL to load and jump to the Linux kernel directly, without the need of loading U-Boot proper. CONFIG_SPL_OS_BOOT=y needs to be passed in the defconfig in order to use Falcon mode.
