config ARM64_CRC32
	bool "Enable support for CRC32 instruction"
	depends on ARM64
	default y
	help
	  ARMv8 implements dedicated crc32 instruction for crc32 calculation.
	  This is faster than software crc32 calculation. This instruction may
	  not be present on all ARMv8.0, but is always present on ARMv8.1 and
	  newer.

config POSITION_INDEPENDENT
	bool "Generate position-independent pre-relocation code"
	depends on ARM64 || CPU_V7A
	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 4K aligned address. This logic relies on the relocation
	  information that is embedded in the binary to support U-Boot
	  relocating itself to the top-of-RAM later during execution.

config INIT_SP_RELATIVE
	bool "Specify the early stack pointer relative to the .bss section"
	depends on ARM64
	default n if ARCH_QEMU
	default y if POSITION_INDEPENDENT
	help
	  U-Boot typically uses a hard-coded value for the stack pointer
	  before relocation. Enable this option to instead calculate the
	  initial SP at run-time. This is useful to avoid hard-coding addresses
	  into U-Boot, so that it can be loaded and executed at arbitrary
	  addresses and thus avoid using arbitrary addresses at runtime.

	  If this option is enabled, the early stack pointer is set to
	  &_bss_start with a offset value added. The offset is specified by
	  SYS_INIT_SP_BSS_OFFSET.

config SYS_INIT_SP_BSS_OFFSET
	int "Early stack offset from the .bss base address"
	depends on ARM64
	depends on INIT_SP_RELATIVE
	default 524288
	help
	  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
	depends on ARM64
	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.

config LNX_KRNL_IMG_TEXT_OFFSET_BASE
	depends on LINUX_KERNEL_IMAGE_HEADER
	hex
	help
	  The value subtracted from CONFIG_SYS_TEXT_BASE to calculate the
	  TEXT_OFFSET value written to the Linux kernel image header.

	  If your CPU has an MPU then you should choose 'y' here unless you
	  know that you do not want to use the MPU.
