Thank you for the link.
 
For the benefit of anyone else who may come accross this post:

I added the following line to "/boot/boot.cmd/"

setenv bootargs "${bootargs} cma=xM"
 
where x is the size of RAM allocated to CMA.
 
I then compiled the file with:

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
 
Hopefully this will help anyone else who runs into this issue.
