Yes, it depends on how much of driver model you use. Here are the
results for this commit for trimslice (./tools/buildman/buildman -b
us-gpio4 trimslice -sS)

13: tegra: Enable driver model
       arm: (for 1/1 boards)  all +2863.0  bss +4.0  data +92.0
rodata +551.0  spl/u-boot-spl:all +8.0  spl/u-boot-spl:data +8.0  text
