    	[Needed for HSDK]
    
    Currently the first page of system (hence RAM base) is assumed to be
    @ CONFIG_LINUX_LINK_BASE, where kernel itself is linked.
    
    However is case of HSDK platform, for reasons explained in that patch,
    this is not true. kernel needs to be linked @ 0x9000_0000 while DDR
    is still wired at 0x8000_0000. To properly account for this 256M of RAM,
    we need to introduce a new option and base page frame accountiing off of
    it.
