I think GPU is a part of SOC. Other bsp meta layer also contain gpu 
userpace binaries.
And, mali userpace binaries are not very generic, there are different in 
hardware versions, software versions and backends.
e.g:
     rk3288's GPU is T76x-r0p0 but rk3288w's GPU is T76x-r1p0, so they 
have to use different binaries.
