From 16448928752308703d47caeb5543714297d30599 Mon Sep 17 00:00:00 2001 From: Leon Anavi Date: Fri, 9 Aug 2019 19:44:40 +0300 Subject: u-boot_2019.07.bbappend: Apply patch for AGL SOTA Recently we have updated u-boot to version 2019.07 to support Raspberry Pi 4 in AGL based on Yocto release Thud. Therefore a new version of the patch from meta-updater-raspberrypi branch warrior has to be applied to successfully build U-Boot when feature agl-sota is enabled.
