Hi,

[ Original RFC and motivation can be found at:
http://marc.info/?l=linux-kbuild&m=130456101131801&w=2 ]

I tried to re-think the order in this serie to address Michal comments.

Main changes since v1 are:
 - include scripts/dtc/' parser in the scope of the patchset
 - do not rename any parser source
 - make lexer file name consistent, ie. name it %.lex.c, not lex.%.c
 - rebase on top of v2.6.39

A few notes:
 - the parser should not include the lexer; however, this has the advantage to
   avoid having to deals with the parser's header.
 - the tuple ( "migrate parser to implicit rules", regen parser) should really
   be one commit, to enforce bisect'ability

Comments welcome!
 - Arnaud
