In theory, yes, but using a fiq is not a straightforward change on recent 
kernel versions.

Freescale FIQ demo code has not been updated since their 3.0.35 kernel, which 
was before the majority of the devicetree migration. (and it was a pretty ugly 
hack, even then).

To get an idea what might be involved.
