commit 3ef9dd0e758e7769b3b3868d5a69d271f343dcbe Author: Dave Frodin dave.frodin@se-eng.com Date: Mon Jan 19 13:33:12 2015 -0700
superio/fintek: Add required changes so F81216H can be used
The amd/lamar mainboard is the first mainboard to use the f81216h. These changes are needed to fix up commit 27a63d77 so the Super I/O builds and functions correctly. - Wrong #include name - Removed global variable in romstage - Missing "case" in switch() - Changed function parameters to pass the unlock key
