config POSITION_INDEPENDENT
	bool "Generate position-independent pre-relocation code"
	help
	  U-Boot expects to be linked to a specific hard-coded address, and to
	  be loaded to and run from that address. This option lifts that
	  restriction, thus allowing the code to be loaded to and executed
	  from almost any address. This logic relies on the relocation
	  information that is embedded into the binary to support U-Boot
	  relocating itself to the top-of-RAM later during execution.

config SYS_INIT_SP_BSS_OFFSET
	int
	help
	  U-Boot typically uses a hard-coded value for the stack pointer
	  before relocation. Define this option to instead calculate the
	  initial SP at run-time. This is useful to avoid hard-coding addresses
	  into U-Boot, so that can be loaded and executed at arbitrary
	  addresses and thus avoid using arbitrary addresses at runtime. This
	  option's value is the offset added to &_bss_start in order to
	  calculate the stack pointer. This offset should be large enough so
	  that the early malloc region, global data (gd), and early stack usage
	  do not overlap any appended DTB.

config LINUX_KERNEL_IMAGE_HEADER
	bool
	help
	  Place a Linux kernel image header at the start of the U-Boot binary.
	  The format of the header is described in the Linux kernel source at
	  Documentation/arm64/booting.txt. This feature is useful since the
	  image header reports the amount of memory (BSS and similar) that
	  U-Boot needs to use, but which isn't part of the binary.

if LINUX_KERNEL_IMAGE_HEADER
config LNX_KRNL_IMG_TEXT_OFFSET_BASE

	  The value subtracted from CONFIG_SYS_TEXT_BASE to calculate the
	  TEXT_OFFSET value written in to the Linux kernel image header.

config SYS_ARM_MPU
	bool 'Use the ARM v7 PMSA Compliant MPU'
	help
	  Some ARM systems without an MMU have instead a Memory Protection
	  Unit (MPU) that defines the type and permissions for regions of
	  memory.
	  If your CPU has an MPU then you should choose 'y' here unless you
	  know that you do not want to use the MPU.
