	  Execute-In-Place allows the kernel to run from non-volatile storage

	  space since the text section of the kernel is not loaded from flash
	  to RAM.  Read-write sections, such as the data section and stack,
	  are still copied to RAM.  The XIP kernel is not compressed since
	  it has to run directly from flash, so it will take more space to
	  store it.  The flash address used to link the kernel object files,
	  and for storing it, is configuration dependent. Therefore, if you
	  say Y here, you must know the proper physical address where to
	  store the kernel image depending on your own flash memory usage.

	  Also note that the make target becomes "make xipImage" rather than
	  "make zImage" or "make Image".  The final kernel binary to put in
	  ROM memory will be arch/riscv/boot/xipImage.

	  SPARSEMEM is required because the kernel text and rodata that are
