	help

	  XTFPGA is the name of Tensilica board family (LX60, LX110, LX200, ML605).

	  This hardware is capable of running a full Linux distribution.

	  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

	  ROM memory will be arch/xtensa/boot/xipImage.

	  If unsure, say N.

config MEMMAP_CACHEATTR

	hex "Cache attributes for the memory address space"

	depends on !MMU

	  If unsure, leave the default value here.

config KERNEL_VIRTUAL_ADDRESS

	hex "Kernel virtual address"

	depends on MMU && XIP_KERNEL

	default 0xd0003000

	help

	  This is the virtual address where the XIP kernel is mapped.

	  XIP kernel may be mapped into KSEG or KIO region, virtual address

	  provided here must match kernel load address provided in

	  KERNEL_LOAD_ADDRESS.

config KERNEL_LOAD_ADDRESS

	hex "Kernel load address"

	default 0x60003000 if !MMU

config VECTORS_OFFSET

	hex "Kernel vectors offset"

	default 0x00003000

	depends on !XIP_KERNEL

	help

	  This is the offset of the kernel image from the relocatable vectors

	  base.

	  If unsure, leave the default value here.

config XIP_DATA_ADDR

	hex "XIP kernel data virtual address"

	depends on XIP_KERNEL

	default 0x00000000

	help

	  This is the virtual address where XIP kernel data is copied.

	  It must be within KSEG if MMU is used.
