SPI Engine is a highly flexible and powerful SPI controller framework.
It consist out of multiple sub-modules which communicate over well defined
interfaces.
This allows a high degree of flexibility and re-usability while at the same time
staying highly customizable and easily extensible.
The core component of the SPI Engine framework is a lean but powerful fully
programmable execution module, which implements the SPI bus control logic.
The SPI Engine execution module is controlled by a command stream which is
generated by a separate module. Different command stream master modules are
available and can be used depending on the system requirements.
For example a software controlled memory mapped command stream offers high
flexibility, while a offload core which executes a pre-programmed command stream
when triggered by an external event allows for very low latency response times.
By using a SPI Engine interconnect it is possible to connect multiple command
stream master modules to a SPI Engine execution module.
Sub-modules
--------------------------------------------------------------------------------
* :ref:`spi_engine execution`: Main module which processes a SPI engine command
stream and implements the SPI bus interface logic.
* :ref:`spi_engine axi`: Memory mapped software accessible interface to a
SPI Engine command stream and/or offload cores.
* :ref:`spi_engine offload`: Stores a SPI Engine command stream, execution is
triggered by an external event.
* :ref:`spi_engine interconnect`: Connects multiple SPI Engine command streams
to a SPI Engine execution module.
Interfaces
--------------------------------------------------------------------------------
* :ref:`spi_engine control-interface`: SPI Engine command stream.
* :ref:`spi_engine offload-control-interface`: Program the command stream stored
in a offload module.
* :ref:`spi_engine spi-bus-interface`: Low-level SPI bus interface.

Validate links uses coroutines to launch multiple tasks concurrently, but do it in bundles to avoid being rate limited. Fixup regmap styling.
