Please add a hash for the license file.

For most other firmware files, we have more fine grained options. When
I look at the nvidia/ folder, it has firmware for various graphics
cards:

gk20a
gm200
gm204
gm206
gm20b
gp100
gp102
gp104
gp106
gp107
gp108
gp10b
gv100
tegra124
tegra186
tegra194
tegra210
tu102
tu104
tu106
tu10x

Size-wise, it goes like this:

116K	./gm200
96K	./gp107
36K	./gp106
44K	./gm206
120K	./gp100
28K	./gm204
340K	./tu10x
148K	./tegra210
116K	./gp108
128K	./tegra194
164K	./gm20b
68K	./gk20a
368K	./gp102
276K	./gv100
128K	./tu106
128K	./tu104
148K	./tegra186
76K	./gp104
196K	./gp10b
272K	./tu102
152K	./tegra124
3,1M	.

So, in practice, on a given platform, you would typically need only
100-200 KB of firmware on the total 3.1 MB.

Best regards,

Thomas
