config BR2_ARM_EABI
	bool "EABI"
	help
	  The EABI is currently the standard ARM ABI, which is used in
	  most projects. It supports both the 'soft' floating point
	  model (in which floating point instructions are emulated in
	  software) and the 'softfp' floating point model (in which
	  floating point instructions are executed using an hardware
	  floating point unit, but floating point arguments to
	  functions are passed in integer registers).

	  The 'softfp' floating point model is link-compatible with
	  the 'soft' floating point model, i.e you can link a library
	  built 'soft' with some other code built 'softfp'.

	  However, passing the floating point arguments in integer
	  registers is a bit inefficient, so if your ARM processor has
	  a floating point unit, and you don't have pre-compiled
	  'soft' or 'softfp' code, using the EABIhf ABI will provide
	  better floating point performances.

	  If your processor does not have a floating point unit, then
	  you must use this ABI.

config BR2_ARM_EABIHF
	bool "EABIhf"
	depends on BR2_ARM_CPU_HAS_FPU
	help
	  The EABIhf is an extension of EABI which supports the 'hard'
	  floating point model. This model uses the floating point
	  unit to execute floating point instructions, and passes
	  floating point arguments in floating point registers.

	  It is more efficient than EABI for floating point related
	  workload. However, it does not allow to link against code
	  that has been pre-built for the 'soft' or 'softfp' floating
	  point models.

	  If your processor has a floating point unit, and you don't
	  depend on existing pre-compiled code, this option is most
	  likely the best choice.

	  This option allows to use software emulated floating
	  point. It should be used for ARM cores that do not include a
	  Vector Floating Point unit, such as ARMv5 cores (ARM926 for
	  example) or certain ARMv6 cores.

config BR2_ARM_FPU_VFPV2
	bool "VFPv2"
	depends on BR2_ARM_CPU_HAS_VFPV2
	help
	  This option allows to use the VFPv2 floating point unit, as
	  available in some ARMv5 processors (ARM926EJ-S) and some
	  ARMv6 processors (ARM1136JF-S, ARM1176JZF-S and ARM11
	  MPCore).

	  Note that this option is also safe to use for newer cores
	  such as Cortex-A, because the VFPv3 and VFPv4 units are
	  backward compatible with VFPv2.

config BR2_ARM_FPU_VFPV3
	bool "VFPv3"
	depends on BR2_ARM_CPU_HAS_VFPV3
	help
	  This option allows to use the VFPv3 floating point unit, as
	  available in some ARMv7 processors (Cortex-A{8, 9}). This
	  option requires a VFPv3 unit that has 32 double-precision
	  registers, which is not necessarily the case in all SOCs
	  based on Cortex-A{8, 9}. If you're unsure, use VFPv3-D16
	  instead, which is guaranteed to work on all Cortex-A{8, 9}.

	  Note that this option is also safe to use for newer cores
	  that have a VFPv4 unit, because VFPv4 is backward compatible
	  with VFPv3. They must of course also have 32
	  double-precision registers.

config BR2_ARM_FPU_VFPV3D16
	bool "VFPv3-D16"
	depends on BR2_ARM_CPU_HAS_VFPV3
	help
	  This option allows to use the VFPv3 floating point unit, as
	  available in some ARMv7 processors (Cortex-A{8, 9}). This
	  option requires a VFPv3 unit that has 16 double-precision
	  registers, which is generally the case in all SOCs based on
	  Cortex-A{8, 9}, even though VFPv3 is technically optional on
	  Cortex-A9. This is the safest option for those cores.

	  Note that this option is also safe to use for newer cores
	  such that have a VFPv4 unit, because the VFPv4 is backward
	  compatible with VFPv3.

config BR2_ARM_FPU_VFPV4
	bool "VFPv4"
	depends on BR2_ARM_CPU_HAS_VFPV4
	help
	  This option allows to use the VFPv4 floating point unit, as
	  available in some ARMv7 processors (Cortex-A{5, 7, 12,
	  15}). This option requires a VFPv4 unit that has 32
	  double-precision registers, which is not necessarily the
	  case in all SOCs based on Cortex-A{5, 7, 12, 15}. If you're
	  unsure, you should probably use VFPv4-D16 instead.

	  Note that if you want binary code that works on all ARMv7
	  cores, including the earlier Cortex-A{8, 9}, you should
	  instead select VFPv3.

config BR2_ARM_FPU_VFPV4D16
	bool "VFPv4-D16"
	depends on BR2_ARM_CPU_HAS_VFPV4
	help
	  This option allows to use the VFPv4 floating point unit, as
	  available in some ARMv7 processors (Cortex-A{5, 7, 12,
	  15}). This option requires a VFPv4 unit that has 16
	  double-precision registers, which is always available on
	  Cortex-A12 and Cortex-A15, but optional on Cortex-A5 and
	  Cortex-A7.

	  Note that if you want binary code that works on all ARMv7
	  cores, including the earlier Cortex-A{8, 9}, you should
	  instead select VFPv3-D16.

config BR2_ARM_FPU_NEON
	bool "NEON"
	depends on BR2_ARM_CPU_HAS_NEON
	help
	  This option allows to use the NEON SIMD unit, as available
	  in some ARMv7 processors, as a floating-point unit. It
	  should however be noted that using NEON for floating point
	  operations doesn't provide a complete compatibility with the
	  IEEE 754.

config BR2_ARM_FPU_NEON_VFPV4
	bool "NEON/VFPv4"
	depends on BR2_ARM_CPU_HAS_VFPV4
	depends on BR2_ARM_CPU_HAS_NEON
	help
	  This option allows to use both the VFPv4 and the NEON SIMD
	  units for floating point operations. Note that some ARMv7
	  cores do not necessarily have VFPv4 and/or NEON support, for
	  example on Cortex-A5 and Cortex-A7, support for VFPv4 and
	  NEON is optional.

config BR2_ARM_FPU_FPV4D16
	bool "FPv4-D16"
	depends on BR2_ARM_CPU_HAS_FPV4
	help
	  This option allows to use the FPv4-SP (single precision)

	  This option allows to use the FPv5-SP (single precision)
	  floating point unit, as available in some ARMv7m processors
	  (Cortex-M7).

	  Note that if you want binary code that works on the earlier
	  Cortex-M4, you should instead select FPv4-D16.

	  This option allows to use the FPv5-DP (double precision)
	  floating point unit, as available in some ARMv7m processors
	  (Cortex-M7).

	  Note that if you want binary code that works on the earlier
	  Cortex-M4, you should instead select FPv4-D16.

config BR2_ARM_FPU_FP_ARMV8
	bool "FP-ARMv8"
	depends on BR2_ARM_CPU_HAS_FP_ARMV8

	bool "NEON/FP-ARMv8"
	depends on BR2_ARM_CPU_HAS_FP_ARMV8
	depends on BR2_ARM_CPU_HAS_NEON
