	  This option allows you to set the maximum amount of memory which

	  access directly, without having to set up a kernel virtual mapping.
	  This can be useful in optimizing the layout of kernel virtual

	depends on ADVANCED_OPTIONS && FLATMEM && (FSL_BOOKE || 44x)
	select NONSTATIC_KERNEL
	help
	  This option enables the kernel to be loaded at any page aligned
	  physical address. The kernel creates a mapping from KERNELBASE to 
	  the address where the kernel is loaded. The page size here implies
	  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.

	  This option is overridden by CONFIG_RELOCATABLE

config RELOCATABLE
	bool "Build a relocatable kernel"
	depends on ADVANCED_OPTIONS && FLATMEM && (44x || FSL_BOOKE)

	help
	  This builds a kernel image that is capable of running at the
	  location the kernel is loaded at, without any alignment restrictions.
	  This feature is a superset of DYNAMIC_MEMSTART and hence overrides it.

	  One use is for the kexec on panic case where the recovery kernel
	  must live at a different physical address than the primary
	  kernel.

	  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
	  setting can still be useful to bootwrappers that need to know the
	  load address of the kernel (eg. u-boot/mkimage).
