	help
	  Enable this to support CPU drivers in SPL. These drivers can set
	  up CPUs and provide information about them such as the model and
	  name. This can be useful in SPL since setting up the CPUs earlier
	  may improve boot performance. Enable this option to build the
	  drivers in drivers/cpu as part of an SPL build.

config SPL_CRYPTO
	bool "Support crypto drivers"
	help
	  Enable crypto drivers in SPL. These drivers can be used to

	  build, for those that support building in SPL (not all drivers do).

config SPL_ENV_SUPPORT
	bool "Support an environment"
	help
	  Enable environment support in SPL. The U-Boot environment provides
	  a number of settings (essentially name/value pairs) which can
	  control many aspects of U-Boot's operation. Normally this is not
	  needed in SPL as it has a much simpler task with less
	  configuration. But some boards use this to support 'Falcon' boot
	  on EXT2 and FAT, where SPL boots directly into Linux without
	  starting U-Boot first. Enabling this option will make env_get()
	  and env_set() available in SPL.

config SPL_SAVEENV
	bool "Support save environment"
	depends on SPL_ENV_SUPPORT
	select SPL_MMC_WRITE if ENV_IS_IN_MMC
	help
	  Enable save environment support in SPL after setenv. By default
	  the saveenv option is not provided in SPL, but some boards need
	  this support in 'Falcon' boot, where SPL need to boot from
	  different images based on environment variable set by OS. For
	  example OS may set "reboot_image" environment variable to
	  "recovery" inorder to boot recovery image by SPL. The SPL read
	  "reboot_image" and act accordingly and change the reboot_image
	  to default mode using setenv and save the environment.

config SPL_ETH
	bool "Support Ethernet"
	depends on SPL_ENV_SUPPORT
	depends on SPL_NET
	help
	  Enable access to the network subsystem and associated Ethernet
	  drivers in SPL. This permits SPL to load U-Boot over an Ethernet
	  link rather than from an on-board peripheral. Environment support
	  is required since the network stack uses a number of environment
	  variables. See also SPL_NET.

config SPL_FS_EXT4
	bool "Support EXT filesystems"
	help
	  Enable support for EXT2/3/4 filesystems with SPL. This permits
	  U-Boot (or Linux in Falcon mode) to be loaded from an EXT

	  Enable support for FPGAs in SPL. Field-programmable Gate Arrays
	  provide software-configurable hardware which is typically used to
	  implement peripherals (such as UARTs, LCD displays, MMC) or
	  accelerate custom processing functions, such as image processing
	  or machine learning. Sometimes it is useful to program the FPGA
	  as early as possible during boot, and this option can enable that
	  within SPL.

config SPL_GPIO
	bool "Support GPIO in SPL"
	help
	  Enable support for GPIOs (General-purpose Input/Output) in SPL.
	  GPIOs allow U-Boot to read the state of an input line (high or
	  low) and set the state of an output line. This can be used to
	  drive LEDs, control power to various system parts and read user
	  input. GPIOs can be useful in SPL to enable a 'sign-of-life' LED,
	  for example. Enable this option to build the drivers in
	  drivers/gpio as part of an SPL build.

config SPL_I2C
	bool "Support I2C"
	help
	  Enable support for the I2C (Inter-Integrated Circuit) bus in SPL.
	  I2C works with a clock and data line which can be driven by a
	  one or more masters or slaves. It is a fairly complex bus but is
	  widely used as it only needs two lines for communication. Speeds of
	  400kbps are typical but up to 3.4Mbps is supported by some
	  hardware. I2C can be useful in SPL to configure power management
	  ICs (PMICs) before raising the CPU clock speed, for example.

	  an SPL build.

config SPL_LIBDISK_SUPPORT
	bool "Support disk partitions"
	select PARTITIONS
	help
	  Enable support for disk partitions within SPL. 'Disk' is something
	  of a misnomer as it includes non-spinning media such as flash (as
	  used in MMC and USB sticks). Partitions provide a way for a disk
	  to be split up into separate regions, with a partition table placed
	  at the start or end which describes the location and size of each
	  'partition'. These partitions are typically uses as individual block
	  devices, typically with an EXT2 or FAT filesystem in each. This
	  option enables whatever partition support has been enabled in
	  U-Boot to also be used in SPL. It brings in the code in disk/.

config SPL_LIBGENERIC_SUPPORT
	bool "Support generic libraries"
	help
	  Enable support for generic U-Boot libraries within SPL. These
	  libraries include generic code to deal with device tree, hashing,

	  you are reading this help text, you most likely have no idea :-)

	  The MMC framework is reduced to bare minimum to be useful. No malloc
	  support is needed for the MMC framework operation with this option
	  enabled. The framework supports exactly one MMC device and exactly
	  one MMC driver. The MMC driver can be adjusted to avoid any malloc
	  operations too, which can remove the need for malloc support in SPL

	bool "Support SPI drivers"
	help
	  Enable support for using SPI in SPL. This is used for connecting
	  to SPI flash for loading U-Boot. See SPL_SPI_FLASH_SUPPORT for
	  more details on that. The SPI driver provides the transport for
	  data between the SPI flash and the CPU. This option can be used to
	  enable SPI drivers that are needed for other purposes also, such
	  as a SPI PMIC.

config SPL_SPI_FLASH_SUPPORT
	bool "Support SPI flash drivers"
	depends on SPL_SPI
	help
	  Enable support for using SPI flash in SPL, and loading U-Boot from
	  SPI flash. SPI flash (Serial Peripheral Bus flash) is named after
	  the SPI bus that is used to connect it to a system. It is a simple
	  but fast bidirectional 4-wire bus (clock, chip select and two data
	  lines). This enables the drivers in drivers/mtd/spi as part of an
	  SPL build. This normally requires SPL_SPI.

	default y if SPI_FLASH
	help
	 Enable lightweight SPL SPI Flash support that supports just reading
	 data/images from flash. No support to write/erase flash. Enable
	 this if you have SPL size limitations and don't need full
	 fledged SPI flash support.

config SPL_SPI_FLASH_SFDP_SUPPORT
	bool "SFDP table parsing support for SPI NOR flashes"

config SPL_THERMAL
	bool "Driver support for thermal devices"
	help
	  Enable support for temperature-sensing devices. Some SoCs have on-chip
	  temperature sensors to permit warnings, speed throttling or even
	  automatic power-off when the temperature gets too high or low. Other
	  devices may be discrete but connected on a suitable bus.

config SPL_WATCHDOG
	bool "Support watchdog drivers"
	imply SPL_WDT if !HW_WATCHDOG
	help
	  Enable support for watchdog drivers in SPL. A watchdog is
	  typically a hardware peripheral which can reset the system when it
	  detects no activity for a while (such as a software crash). This
	  enables the drivers in drivers/watchdog as part of an SPL build.

config SPL_YMODEM_SUPPORT
	bool "Support loading using Ymodem"
	depends on SPL_SERIAL
	help
	  While loading from serial is slow it can be a useful backup when
	  there is no other option. The Ymodem protocol provides a reliable
	  means of transmitting U-Boot over a serial line for using in SPL,
	  with a checksum to ensure correctness.

config SPL_ATF_NO_PLATFORM_PARAM
	bool "Pass no platform parameter"
	depends on SPL_ATF
	help
	  While we expect to call a pointer to a valid FDT (or NULL)
	  as the platform parameter to an ATF, some ATF versions are
	  not U-Boot aware and have an insufficiently robust parameter
	  validation to gracefully reject a FDT being passed.

	  If this option is enabled, the spl_atf os-type handler will
	  always pass NULL for the platform parameter.

	  If your ATF is affected, say Y.

	  Use external 8 to 24 Mhz clock signal as source of main clock instead
	  of an external crystal oscillator.
	  This option disables the internal driving on the XOUT pin.
	  The external source has to provide a stable clock on the XIN pin.
	  If this option is disabled, the SoC expects a crystal oscillator
	  that needs driving on both XIN and XOUT lines.
