From abc6eee0e76f5418f64f8a95878ac2bd6d2b2e69 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 12 Sep 2021 00:40:00 +0200 Subject: [PATCH] ARM: imx: mx5: Add altbootcmd and resets to M53Menlo Bulletproof the default boot command with reset statements in case any command in the chain would fail. In case a failure were to happen, the board will reset, increment boot counter and retry the procedure. In case the failures persist and the boot counter reaches the bootlimit, U-Boot starts altbootcmd instead of the default bootcmd boot command. The altbootcmd swaps the default boot partition for the other boot partition, which is an identical copy or an older copy, and tries booting from that one instead.
