From 5a6440cac77db8083aa9b7f260e0ff3e994e7834 Mon Sep 17 00:00:00 2001 From: Christopher Spinrath Date: Sat, 9 Dec 2017 16:37:43 +0100 Subject: ARM: imx: cm_fx6: env: don't run boot scripts twice Boot scripts located in the root directory of the first partition of USB, mmc, and SATA drives are executed twice: first by the distro boot command and then by the legacy boot command. This may have weird side effects if those scripts only change or extend the environment (including parts of the boot command itself). Removing the script execution from the legacy boot command has its own caveats. For instance, the distro boot command may execute the boot.scr on the mmc drive, then the boot.scr on the SATA drive, before the legacy boot command actually boots from the mmc drive. However, the current behavior would only execute the boot.scr once more before the actual boot, but it does not prevent the script located on the SATA drive from being executed, and thus, both scripts from being mixed up. Considering that the legacy boot command is only in place to boot old (standard) installations, let's go with the resolution having less custom code and remove the script execution from the legacy boot command.
