From 3b81d1199347b2fd250d72bb4df39e15f975b6ed Mon Sep 17 00:00:00 2001 From: Marco Felsch Date: Wed, 30 Oct 2019 18:03:39 +0100 Subject: parameter: strip leading and trailing whitespaces My initial bug was the following: I set the global.boot.default="boot1 boot2 " and executed the 'boot' command. If both targets are not bootable barebox starts to execute the boot scripts found under /env/boot. This is because of the command/boot.c implementation and the leading whitespace. Without the whitespace only the two desired boot targets are tried. IMHO leading and trailing whitespaces are error-prone in many cases. If someone wants to concatenate strings he/she should add spaces on purpose. So I fixed the bug above globally by always stripping leading and trailing whitespaces.
