From 1b96da67a0f5c70e4096bec9ce0769925f70513f Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 10 Jul 2019 11:04:13 -0600 Subject: [PATCH] chromium: Update docs to clone vboot_reference directly We don't need a full checkout of Chrome OS to build U-Boot with Chromium OS verified boot. Update the instructions accordingly and fix a typo which joins the output directory and defconfig.
