Subject: [PATCH 1/1] mb/dell/optiplex_9020: Implement late HWM initialization
There are 4 different chassis types specified by vendor firmware, each
with a slightly different HWM configuration.
The chassis type to use is determined at runtime by reading a set of
-4 PCH GPIOs: 70, 38, 17, and 0.
+4 PCH GPIOs: 70, 38, 17, and 1.
Additionally vendor firmware also provides an option to run the fans at
full speed. This is substituted with a coreboot nvram option in this
