IMO, We should not limit to Platform specific drivers. I think, all
platform specific information can go here. For x86 case, may be x86 tuning 
guide can be moved here from QSG.

I think, it would more appropriate to call "OCTEONTX Board Support Package"
or something similar as it has details for PF driver, ARM64 toolchain and
Rootfile system etc
