From ba9a6708ec51c294a9674d6901a8be7c3ef76f57 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Fri, 28 Mar 2014 12:03:38 -0400 Subject: [PATCH] am335x_evm: Make SPL_OS also check the boot_os variable for falcon mode We use the same variable as a3m071 in the environment to determine if we should boot into Linux or U-Boot. This is useful on boards like Beaglebone Black or AM335x GP EVM where we have persistent storage for the environment.
