It depends on how you've configured u-boot.  Connect to u-boot and run:

printenv bootcmd

If it looks like this:

bootcmd=setenv bootargs ${bootargs_console}; run bootcmd_usb; bootm 0x00800000 0x01100000

(bootcmd_usb might be bootcmd_mmc or bootcmd_sata)

You can use:

setenv bootcmd 'setenv bootargs ${bootargs_console} apparmor=1 security=apparmor; run bootcmd_usb; bootm 0x00800000 0x01100000'
saveenv

or you could introduce a new variable:

setenv bootargs_security 'apparmor=1 security=apparmor'
setenv bootcmd 'setenv bootargs ${bootargs_console} ${bootargs_security}; run bootcmd_usb; bootm 0x00800000 0x01100000'
saveenv

If you looks different, please post the output of "printenv" (not
"printenv bootcmd", just "printenv") here.
