Copied wholeheartedly from board/Marvell/guruplug and modified to add support for SPI NOR flash.
Also, the following features are used: - Use the Marvell Integrated RTC. - display Marvell CPU/L2/etc speeds if requested.
Note: this still uses MACH_TYPE_GURUPLUG until MACH_TYPE_DREAMPLUG is accepted into mainline Linux. The source from Globalscale did the same.
