This is a tool written in C which does basically the same job as regtools' headergen_v2, but using a new input format which is less verbose than XML. In the interests of simplicity it omits some features that regtools does support, like variant registers or the SoC selector stuff so it cannot completely replace regtools on the i.MX platforms that use these features. RegGen doesn't generate API macros like regtools does; instead these are expected to be maintained by hand, since it's arguably easier to do that way. Since RegGen has no dependencies beyond a C compiler it can be integrated with the build system without adding any new build time dependencies. This will allow generating headers automatically, which is a substantial improvement over running headergen_v2 by hand and committing the generated output. The RegGen tool itself is licensed as GPLv3+, but generated headers can be licensed as the user chooses. Change-Id: If18f9577f8f4df6e2c97c1665b725773dd5466f0
