These tools allow one to read a register description in a XML file and to produce something useful out of it. Three example programs are written: - tester which simply prints the register tree - headergen which produces a set of headers with the #define - hwemulgen which produces something for the hwemul tool (to come) Change-Id: I52573688b29d5faeaf64ce7c5ffe08ee8db3d33c
