+config DM
+ bool "Enable Driver Model"
+ help
+ This config option enables Driver Model. This brings in the core
+ support, including scanning of platform data on start-up. If
+ CONFIG_OF_CONTROL is enabled, the device tree will be scanned also
+ when available.
+
+config SPL_DM
+ bool "Enable Driver Model for SPL"
+ depends on DM && SPL
+ help
+ Enable driver model in SPL. You will need to provide a
+ suitable malloc() implementation. If you are not using the
+ full malloc() enabled by CONFIG_SYS_SPL_MALLOC_START,
+ consider using CONFIG_SYS_MALLOC_SIMPLE. In that case you
+ must provide CONFIG_SYS_MALLOC_F_LEN to set the size.
+ In most cases driver model will only allocate a few uclasses
+ and devices in SPL, so 1KB should be enable. See
+ CONFIG_SYS_MALLOC_F_LEN for more details on how to enable it.
+
+config DM_WARN
+ bool "Enable warnings in driver model"
+ depends on DM
+ default y
+ help
+ The dm_warn() function can use up quite a bit of space for its
+ strings. By default this is disabled for SPL builds to save space.
+ This will cause dm_warn() to be compiled out - it will do nothing
+ when called.
+
+config DM_DEVICE_REMOVE
+ bool "Support device removal"
+ depends on DM
+ default y
+ help
+ We can save some code space by dropping support for removing a
+ device. This is not normally required in SPL, so by default this
+ option is disabled for SPL.
+
+ Note that this may have undesirable results in the USB subsystem as
+ it causes unplugged devices to linger around in the dm-tree, and it
+ causes USB host controllers to not be stopped when booting the OS.
+
+config DM_STDIO
+ bool "Support stdio registration"
+ depends on DM
+ default y
+ help
+ Normally serial drivers register with stdio so that they can be used
+ as normal output devices. In SPL we don't normally use stdio, so
+ we can omit this feature.
+
+config DM_SEQ_ALIAS
+ bool "Support numbered aliases in device tree"
+ depends on DM
+ default y
+ help
+ Most boards will have a '/aliases' node containing the path to
+ numbered devices (e.g. serial0 = &serial0). This feature can be
+ disabled if it is not required, to save code space in SPL.
+
+config REGMAP
+ bool "Support register maps"
+ depends on DM
+ help
+ Hardware peripherals tend to have one or more sets of registers
+ which can be accessed to control the hardware. A register map
+ models this with a simple read/write interface. It can in principle
+ support any bus type (I2C, SPI) but so far this only supports
+ direct memory access.
+
+config SYSCON
+ bool "Support system controllers"
+ depends on REGMAP
+ help
+ Many SoCs have a number of system controllers which are dealt with
+ as a group by a single driver. Some common functionality is provided
+ by this uclass, including accessing registers via regmap and
+ assigning a unique number to each.
+
+config DEVRES
+ bool "Managed device resources"
+ depends on DM
+ help
+ This option enables the Managed device resources core support.
+ Device resources managed by the devres framework are automatically
+ released whether initialization fails half-way or the device gets
+ detached.
+
+ If this option is disabled, devres functions fall back to
+ non-managed variants. For example, devres_alloc() to kzalloc(),
+ devm_kmalloc() to kmalloc(), etc.
+
+config DEBUG_DEVRES
+ bool "Managed device resources debugging functions"
+ depends on DEVRES
+ help
+ If this option is enabled, devres debug messages are printed.
+ Also, a function is available to dump a list of device resources.
+ Select this if you are having a problem with devres or want to
+ debug resource management for a managed device.
+
+ If you are unsure about this, Say N here.
+
+config SIMPLE_BUS
+ bool "Support simple-bus driver"
+ depends on DM && OF_CONTROL
+ default y
+ help
+ Supports the 'simple-bus' driver, which is used on some systems.
+
+config SPL_SIMPLE_BUS
+ bool "Support simple-bus driver in SPL"
+ depends on SPL_DM && SPL_OF_CONTROL
+ default n
+ help
+ Supports the 'simple-bus' driver, which is used on some systems
+ in SPL.
