	default y if XTENSA_VARIANT_DC233C || XTENSA_VARIANT_CUSTOM
	help
	  Earlier version initialized the MMU in the exception vector
	  before jumping to _startup in head.S and had an advantage that
	  it was possible to place a software breakpoint at 'reset' and
	  then enter your normal kernel breakpoints once the MMU was mapped
	  to the kernel mappings (0XC0000000).

	  This unfortunately won't work for U-Boot and likely also wont
	  work for using KEXEC to have a hot kernel ready for doing a
	  KDUMP.

	  So now the MMU is initialized in head.S but it's necessary to
	  use hardware breakpoints (gdb 'hbreak' cmd) to break at _startup.
	  xt-gdb can't place a Software Breakpoint in the  0XD region prior
	  to mapping the MMU and after mapping even if the area of low memory
	  was mapped gdb wouldn't remove the breakpoint on hitting it as the
	  PC wouldn't match. Since Hardware Breakpoints are recommended for
	  Linux configurations it seems reasonable to just assume they exist
	  and leave this older mechanism for unfortunate souls that choose
	  not to follow Tensilica's recommendation.

	  Selecting this will cause U-Boot to set the KERNEL Load and Entry
	  address at 0x00003000 instead of the mapped std of 0xD0003000.

	  If in doubt, say Y.

config XIP_KERNEL
	bool "Kernel Execute-In-Place from ROM"
	depends on PLATFORM_HAVE_XIP
	help
	  Execute-In-Place allows the kernel to run from non-volatile storage
	  directly addressable by the CPU, such as NOR flash. This saves RAM
	  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 Image" or "make uImage". The final kernel binary to put in
