config BROKEN
	bool
	help
	  This option cannot be enabled. It is used as dependency
	  for broken and incomplete features.

config LOCALVERSION
	string "Local version - append to U-Boot release"
	help
	  Append an extra string to the end of your U-Boot version.
	  This will show up in your boot log, for example.
	  The string you set here will be appended after the contents of
	  any files with a filename matching localversion* in your
	  object and source tree, in that order.  Your total string can
	  be a maximum of 64 characters.

config LOCALVERSION_AUTO
	bool "Automatically append version information to the version string"
	default y
	help
	  This will try to automatically determine if the current tree is a
	  release tree by looking for Git tags that belong to the current
	  top of tree revision.

	  A string of the format -gxxxxxxxx will be added to the localversion
	  if a Git-based tree is found.  The string generated by this will be
	  appended after any matching localversion* files, and after the value
	  set in CONFIG_LOCALVERSION.

	  (The actual string used here is the first eight characters produced
	  by running the command:

	    $ git rev-parse --verify HEAD

	  which is done within the script "scripts/setlocalversion".)

config CC_OPTIMIZE_FOR_SIZE
	bool "Optimize for size"
	default y
	help
	  Enabling this option will pass "-Os" instead of "-O2" to gcc
	  resulting in a smaller U-Boot image.

	  This option is enabled by default for U-Boot.

config DISTRO_DEFAULTS
	bool "Select defaults suitable for booting general purpose Linux distributions"
	default y if ARCH_SUNXI || TEGRA
	default y if ARCH_LS2080A
	default y if ARCH_MESON
	default y if ARCH_ROCKCHIP

	select CMD_FAT
	select CMD_FS_GENERIC
	imply CMD_MII
	select CMD_PING
	select CMD_PART
	select HUSH_PARSER
	help
	  Select this to enable various options and commands which are suitable
	  for building u-boot for booting general purpose Linux distributions.

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

config SYS_MALLOC_F_LEN
	hex "Size of malloc() pool before relocation"
	depends on SYS_MALLOC_F
	default 0x400
	help

	  initial serial device and any others that are needed.

config SPL_SYS_MALLOC_F_LEN
        hex "Size of malloc() pool in SPL before relocation"
        depends on SYS_MALLOC_F
        default SYS_MALLOC_F_LEN

config TPL_SYS_MALLOC_F_LEN
        hex "Size of malloc() pool in TPL before relocation"
        depends on SYS_MALLOC_F
        default SYS_MALLOC_F_LEN

menuconfig EXPERT
	bool "Configure standard U-Boot features (expert users)"
	default y
	help
	  This option allows certain base U-Boot options and settings
	  to be disabled or tweaked. This is for specialized
	  environments which can tolerate a "non-standard" U-Boot.
	  Use this only if you really know what you are doing.

if EXPERT
	config SYS_MALLOC_CLEAR_ON_INIT
	bool "Init with zeros the memory reserved for malloc (slow)"
	default y if !ARCH_ROCKCHIP
	help
	  This setting is enabled by default. The reserved malloc
	  memory is initialized with zeros, so first malloc calls
	  will return the pointer to the zeroed memory. But this
	  slows the boot time.

	  It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
	  value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
	  Then the boot time can be significantly reduced.
	  Warning:
	  When disabling this, please check if malloc calls, maybe
	  should be replaced by calloc - if one expects zeroed memory.

config TOOLS_DEBUG
	bool "Enable debug information for tools"
	help
	  Enable generation of debug information for tools such as mkimage.
	  This can be used for debugging purposes. With debug information
	  it is possible to set breakpoints on particular lines, single-step
	  debug through the source code, etc.

endif # EXPERT

config PHYS_64BIT
	bool "64bit physical address support"
	help
	  Say Y here to support 64bit physical memory address.
	  This can be used not only for 64bit SoCs, but also for
	  large physical address extention on 32bit SoCs.
