From: Constantine Shulyupin <const@xxxxxxxxxxxxx>
Problem:
- FDT is supported only by generic OMAP board initialization in arch/arm/mach-omap2/board-generic.c and lacks some configurations, which are not yet configured in FDT (USB for example).
Solution:
- arch/arm/mach-omap2/board-omap4panda.c supports initialization with FDT and without it.
