Select this option to enable the legacy stpio interface. No
code within the kernel uses this API, it is retained only for
drivers outside the kernel which might still need it.
config STM_DMA
bool "STMicroelectronics DMA API"
select SH_DMA_API
select LIBELF
default y
---help---
Selecting this option will provide support for STMicroelectronics'
custom DMA API. This API provides support for data transfers of
various dimensions and complex linked list operations. In addition
to these free-running operations it also allows management of the
paced-transfer peripherals on recent STM parts.
If you have a device from STMicroelectronics, then say Y here.
Otherwise say N.

---help---
Many of the ST system-on-chip devices have multiple CPUs, where a
master CPU running Linux has control over a number of slave CPUs,
which are usually used to run dedicated algorithms.
Enabling this option will add support to the Linux kernel to
control these slave CPUs, reserve memory for them, and thus allow
code to be downloaded onto them and executed.
Adding in the command line the following string:
coprocessor_mem=[offset]:size0[,size1][,size2]...
where:
offset defines where the co-processors region starts.
It's an offset from ST40 RAM start.
size{n} defines the region size for the n.th slave core (max 16M).
Example: coprocessor_mem=32m:16m,16m

bool "STM coprocessor debug"
default n
---help---
Enable this option to print out information about the slave CPUs
addresses and operations you are using for coprocessor.
config STM_RNG
bool "STM Random Number Generator Support"
default y
---help---
This option adds support for the hardware Random Number Generator
(RNG) present on different STMicroelectronics SoCs. It allows the
RNG to feed /dev/random with entropy thereby ensuring real
random numbers from this device.
Without this option, /dev/random has little entropy and is not
useful. In fact, it may block for a long time while waiting for
entropy.
This option should always be enabled for relevant SoCs.
This option can be used in conjunction with the /dev/hw_random
driver found in the char drivers menu.

select PM_RUNTIME
help
This option enables the STMicroelectronics Power Management
Scheme (PMS).
This is a kernel framework based around power profiles (pms_state),
where the designer can specify devices power states and the
clock frequency rates.
Moving the system between pms_states the user application can
tune the power consumption according with what the system is doing.
config PMS_CHECK_GROUP
bool "PMS always checks the state group"
depends on PMS
default n
help
Enable this option if the state group has to be controlled.
When a group of pms_states are enabled in the same time, this option
forces the PMS to check that there is no conflict inside the group
itself. In case of conflict the group is rejected.
