config ELF_ALIGN_LOG2
	int "Log2 Section Alignment"
	default 2
	---help---
		Align all sections to this Log2 value:  0->1, 1->2, 2->4, etc.

config ELF_STACKSIZE
	int "ELF Stack Size"
	default DEFAULT_TASK_STACKSIZE
	---help---
		This is the default stack size that will be used when starting ELF binaries.

config ELF_BUFFERSIZE
	int "ELF I/O Buffer Size"
	default 32
	---help---
		This is an I/O buffer that is used to access the ELF file.  Variable length items
		will need to be read (such as symbol names).  This is really just this initial
		size of the buffer; it will be reallocated as necessary to hold large symbol
		names.  Default: 32

config ELF_BUFFERINCR
	int "ELF I/O Buffer Realloc Increment"
	default 32
	---help---
		This is an I/O buffer that is used to access the ELF file.  Variable length items
		will need to be read (such as symbol names).  This value specifies the size
		increment to use each time the buffer is reallocated.  Default: 32

config ELF_DUMPBUFFER
	bool "Dump ELF buffers"
	default n
	depends on DEBUG_INFO
	---help---
		Dump various ELF buffers for debug purposes

config ELF_EXIDX_SECTNAME
	string "ELF Section Name for Exception Index"
	default ".ARM.exidx"
	depends on CXX_EXCEPTION && ARCH_ARM
	---help---
		Set the name string for the exception index section on the ELF modules to
		be loaded by the ELF binary loader.

		This is needed to support exception handling on loadable ELF modules.

config ELF_RELOCATION_BUFFERCOUNT
	int "ELF Relocation Table Buffer Count"
	default 256
	---help---
		This is a relocation buffer that is used to store elf relocation table to
		reduce access fs. Default: 256

config ELF_SYMBOL_CACHECOUNT
	int "ELF SYMBOL Table Cache Count"
	default 256
	---help---
		This is a cache that is used to store elf symbol table to
		reduce access fs. Default: 256

config ELF_COREDUMP
	bool "ELF Coredump"
	depends on ARCH_HAVE_TCBINFO
	default n
	---help---
		Generate ELF core dump to provide information about the CPU state and the
		memory state of program.
		The memory state embeds a snapshot of all segments mapped in the
		memory space of the program. The CPU state contains register values
		when the core dump has been generated.

config ELF_LOADTO_LMA
	bool "ELF load sections to LMA"
	default n
	---help---
		Load all section to LMA not VMA, so the startup code(e.g. start.S) need
		relocate .data section to the final address(VMA) and zero .bss section
		by self.
