	17	string "Local version - append to U-Boot release"
	18	help
	19	Append an extra string to the end of your U-Boot version.
	20	This will show up on your boot log, for example.
	21	The string you set here will be appended after the contents of
	22	any files with a filename matching localversion* in your
	23	object and source tree, in that order. Your total string can
	24	be a maximum of 64 characters.
	25
	26	config LOCALVERSION_AUTO
	27	bool "Automatically append version information to the version string"
	28	default y
	29	help
	30	This will try to automatically determine if the current tree is a
	31	release tree by looking for git tags that belong to the current
	32	top of tree revision.
	33
	34	A string of the format -gxxxxxxxx will be added to the localversion
	35	if a git-based tree is found. The string generated by this will be
	36	appended after any matching localversion* files, and after the value
	37	set in CONFIG_LOCALVERSION.
	38
	39	(The actual string used here is the first eight characters produced
	40	by running the command:
	41
	42	$ git rev-parse --verify HEAD
	43
	44	which is done within the script "scripts/setlocalversion".)
	45
	46	config CC_OPTIMIZE_FOR_SIZE
	47	bool "Optimize for size"
	48	default y
	49	help
	50	Enabling this option will pass "-Os" instead of "-O2" to gcc
	51	resulting in a smaller U-Boot image.
	52
	53	This option is enabled by default for U-Boot.

	55	config SYS_MALLOC_F
	56	bool "Enable malloc() pool before relocation"
	57	default y if DM
	58	help
	59	Before relocation memory is very limited on many platforms. Still,
	60	we can provide a small malloc() pool if needed. Driver model in
	61	particular needs this to operate, so that it can allocate the
	62	initial serial device and any others that are needed.

	74	menuconfig EXPERT
	75	bool "Configure standard U-Boot features (expert users)"
	76	default y
	77	help
	78	This option allows certain base U-Boot options and settings
	79	to be disabled or tweaked. This is for specialized
	80	environments which can tolerate a "non-standard" U-Boot.
	81	Only use this if you really know what you are doing.
	82
	83	if EXPERT
	84	config SYS_MALLOC_CLEAR_ON_INIT
	85	bool "Init with zeros the memory reserved for malloc (slow)"
	86	default y
	87	help
	88	This setting is enabled by default. The reserved malloc
	89	memory is initialized with zeros, so first malloc calls
	90	will return the pointer to the zeroed memory. But this
	91	slows the boot time.
	92
	93	It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
	94	value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
	95	Then the boot time can be significantly reduced.
	96	Warning:
	97	When disabling this, please check if malloc calls, maybe
	98	should be replaced by calloc - if expects zeroed memory.

	119	bool "Enable SDRAM location for SPL stack"
	120	help
	121	SPL starts off execution in SRAM and thus typically has only a small
	122	stack available. Since SPL sets up DRAM while in its board_init_f()
	123	function, it is possible for the stack to move there before
	124	board_init_r() is reached. This option enables a special SDRAM
	125	location for the SPL stack. U-Boot SPL switches to this after
	126	board_init_f() completes, and before board_init_r() starts.

	143	bool "Support Flattened Image Tree"
	144	help
	145	This option allows to boot the new uImage structrure,
	146	Flattened Image Tree. FIT is formally a FDT, which can include
	147	images of various types (kernel, FDT blob, ramdisk, etc.)
	148	in a single blob. To boot this new uImage structure,
	149	pass the the address of the blob to the "bootm" command.

	160	help
	161	This option enables signature verification of FIT uImages,
	162	using a hash signed and verified using RSA. If
	163	CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive
	164	hashing is available using hardware, RSA library will use it.

	167	config SYS_EXTRA_OPTIONS
	168	string "Extra Options (DEPRECATED)"
	169	help
	170	The old configuration infrastructure (= mkconfig + boards.cfg)
	171	provided the extra options field. If you have something like
	172	"HAS_BAR,BAZ=64", the optional options
	173	#define CONFIG_HAS
	174	#define CONFIG_BAZ 64
	175	will be defined in include/config.h.
	176	This option was prepared for the smooth migration from the old
	177	configuration to Kconfig. Since this option will be removed sometime,
	178	new boards should not use this option.
