Added: LinuxBIOSv3/superio/fintek/ LinuxBIOSv3/superio/fintek/f71805f/ LinuxBIOSv3/superio/fintek/f71805f/Makefile LinuxBIOSv3/superio/fintek/f71805f/dts LinuxBIOSv3/superio/fintek/f71805f/f71805f.h LinuxBIOSv3/superio/fintek/f71805f/stage1.c LinuxBIOSv3/superio/fintek/f71805f/superio.c Modified: LinuxBIOSv3/Kconfig Log: I know there is still an ongoing discussion on the list about this patch, and how support for superios might look in the future. This code (like all the rest, too) will certainly change and evolve in the future, as v3 evolves.
-----
Add support for the Fintek F71805f to LinuxBIOSv3. It hasn't been tested yet because something's failing to build elsewhere, but the stage1 does build, and for the moment that's what matters. It's based on working v2 code so it should work fine.
