The huge size and growing number of different builds of the Nvidia GSP
firmware are a real problem.  I don't think there's anything that we can
do about that in the firmware package.  However:

1. This is exacerbated by the fact that the nouveau driver declares
multiple versions of the GSP firmware for some chips with
MODULE_FIRMWARE(), but only needs one (per chip).  In the short term I
think we should patch nouveau to remove the MODULE_FIRMWARE()
declarations for v535.113.01 for chips where it prefers v570.144.

2. In the medium term we need to move to using generic framebuffer
drivers in the initramfs, but several packages have to be changed to
make that work.
