  	  This option enables the kernel to be loaded at any page aligned

  	  the TLB page size of the mapping for kernel on the particular platform.
  	  Please refer to the init code for finding the TLB page size.
  
  	  DYNAMIC_MEMSTART is an easy way of implementing pseudo-RELOCATABLE
  	  kernel image, where the only restriction is the page aligned kernel
  	  load address. When this option is enabled, the compile time physical 
  	  address CONFIG_PHYSICAL_START is ignored.

  	  Note: If CONFIG_RELOCATABLE=y, then the kernel runs from the address
  	  it has been loaded at and the compile time physical addresses
  	  CONFIG_PHYSICAL_START is ignored.  However CONFIG_PHYSICAL_START
