b568bfa813 Misoc LM3: Add Misoc Ethernet driver. Integrate network support into configs/misoc/hello. Remove configs/misoc/include/generated directory. I suppose the the intent now is that this is a symbolic link? DANGER! This means that you cannot compile this code with first generating these files a providing a symbolic link to this location! 2016-11-28 11:08:29 -06:00

21e42d18c1 ARMv7-A/i.MX6 SMP: Move SMP coherernt cache setup to earlier in initialization of CPUn, n>0 2016-11-27 11:28:24 -06:00

b5bfe8af17 The Smoothie project needs to compile C++ inside config/boardname/src/ to use with High Priority Interruption, then I modified the board configs Makefile to support it, see attached patch. 
It works fine for the first time compilation, but if we execute:

$ touch config/boardname/src/Pin.cxx

And execute "make" it will not detect that Pin.cxx was modified. I think there is some other place I should modify, but I didn't find it.
