[U-Boot] [PATCH V2 5/5] ARM: OMAP: Add arch_cpu_init function

Wed Apr 24 12:41:25 CEST 2013
The boot parameters passed from SPL to UBOOT
must be saved as a part of uboot's gd data
as early as possible, before we will inadvertently
overwrite it. So adding a arch_cpu_init for the required
Socs to save it.
