Sorry, I misunderstood your original explanation - in that case you cannot use 
STAGING_KERNEL_DIR because it will only exist after the kernel has been built.

It seems a bit odd that you'd need to build the firmware first and then use that 
as an input to the kernel build - is it baking the firmware into the module 
instead of loading the firmware at runtime like most other drivers?

Cheers,
Paul
