Actually, I don't think we can.  This is the actual GSP-RM ELF image
you're talking about.  This comes packaged as one binary blob and it's
intended to be mostly opaque.  We can't just disassemble the ELF
sections and then re-assemble them in the driver.

Unfortunately, for pre-Hopper booting, we need to do a little
pre-processing on the image, referencing the ELF sections, and based
on data from fuses that cannot be read in user-space.
