Hi, folks. How do I add arguments to the kernel boot command line for Debian Jessie on a Marvell Kirkwood device? I want to use AppArmor on a QNAP NAS, and the wiki says I need to enable the appropriate LSM with kernel args apparmor=1 security=apparmor, but I don't know how to configure this on Debian's ARM port. The wiki provides instructions for GRUB, but I think this box uses U-Boot, and I'm not familiar with its configuration.
