config TARGET_ARCH
	string
	default "arm"

config FORCE_OPTIONS_FOR_ARCH
	bool
	default y
	select ARCH_ANY_ENDIAN
	select ARCH_HAS_UCONTEXT
	select ARCH_HAS_DEPRECATED_SYSCALLS

config CONFIG_ARM_EABI
	bool "Build for EABI"
	help
	  If you say 'y' here, functions and constants required by the
	  ARM EABI will be built into the library.  You should say 'y'
	  if your compiler uses the ARM EABI, in which case you will also
	  need a kernel supporting the EABI system call interface.

	  If you say 'n' here, then the library will be built for the
	  old Linux ABI.

config COMPILE_IN_THUMB_MODE
	bool "Build using Thumb mode"
	select USE_BX
	select USE_LDREXSTREX
	help
	  Say 'y' here to force building uClibc in thumb mode.
	  Say 'n' to use your compiler's default mode.

config USE_BX
	bool "Use BX in function return"
	help
	  Say 'y' to use BX to return from functions on your thumb-aware
	  processor. Say 'y' if you need to use interworking. Say 'n' if not.
	  It is safe to say 'y' even if you're not doing interworking.

config USE_LDREXSTREX
	bool "Use load-store exclusive ASM ops (not supported in SmartFusion)"
	depends on COMPILE_IN_THUMB_MODE
	default n
	help
	  Say 'y' to use LDREX/STREX ASM ops.
