Patch from Tony Lindgren This patch adds support for omap24xx series of processors. The files live in arch/arm/mach-omap2, and share common files with omap15xx and omap16xx processors in arch/arm/plat-omap. Omap24xx support was originally added for 2.6.9 by TI. This code was then improved and integrated to share common code with omap15xx and omap16xx processors by various omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak, Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah et al.
