Depends on if you want to have it in the mainline kernel or want to keep it outside :-) . Also there shouldn't even be more in any new mach-X than is in mach-rockchip currently. Meaning the only thing that should be added there is the "rockchip,rk2918" compatible string in rockchip.c > I'm thinking I'll only going to put in the pieces to make it work with > my board, since I can't test anything else, unless somebody with the > hw wants to volunteer to test it?

I'm not sure I understand you here. Nowadays the _only_ board-specific part is the rk2918-foo.dts devicetree file describing the actual board. The rest is not supposed to have any board-specific code. The sane approach would still be: - debug serial - pinctrl - clock - any device drivers that need adapting But whatever you do, don't invest to much time in drivers, that already have an equivalent in the kernel.
