ARM: OMAP2+: AM43x: early init
Minimal early init - PRCM initialization not yet taken care.
Control module is similar (base address, feature register etc.) as
that of AM335x, while PRCM base address is different. Instead of
adding a new header file for AM43x, PRCM base address is added in
AM335x header file as it is similar to it to a large extent.
