commit dd213b2d401fe27a2ebc80ad4fc0d38106b881f2 Author: Marc Jones marc.jones@se-eng.com Date: Wed Oct 30 16:18:07 2013 -0600
sio1007: Properly build '.c' files
Properly build the super i/o .c files. This prevents including the .c file directly in romstage, which is generally bad practice. Adding a Makefile and a .h file to include.
