But as discussed/demonstrated earlier in the thread spaces in there
shouldn't cause a problem. What actual problem did you see resulting
from there being spaces here?

Let me assume that your cmdline.txt contains:
    foo bar
then the above should result in
    LINUX_KERNEL_CMDLINE="foo bar"
and in turn the boot.scr will have:
    setenv bootargs ${bootargs} foo bar

So I'm afraid I'm still not clear exactly what issue you are seeing.

Please can you post:

 * the contents of your /boot/cmdline.txt
 * the contents of the flash kernel db entry you have added for the
   RPi2
 * the resulting generated boot.scr.
 * a full serial console log booting with that boot.scr
