config REGMAP
support any bus type (I2C, SPI) but so far this only supports
direct memory access.
+config SPL_REGMAP
+ bool "Support register maps in SPL"
+ 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
by this uclass, including accessing registers via regmap and
assigning a unique number to each.
+config SPL_SYSCON
+ bool "Support system controllers in SPL"
+ 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
devm_kmalloc() to kmalloc(), etc.
config DEBUG_DEVRES
- bool "Managed device resources verbose debug messages"
+ 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.

+ If this option is enabled, the reg property will be translated
+ using the fdt_translate_address() function. This is necessary
+ on some platforms (e.g. MVEBU) using complex "ranges"
+ properties in many nodes. As this translation is not handled
+ correctly in the default simple_bus_translate() function.
+
+ If this option is not enabled, simple_bus_translate() will be
+ used for the address translation. This function is faster and
+ smaller in size than fdt_translate_address().
