Many System on Chip(SoC) solutions are complex with multiple processors
on the same die dedicated to either general purpose of specialized
functions. Many examples do exist in today's SoCs from various vendors.
Typical examples are micro controllers such as an ARM M3/M0 doing a
offload of specific function such as event integration or power
management or controlling camera etc.
Traditionally, the responsibility of loading up such a processor with a
firmware and communication has been with a High Level Operating
System(HLOS) such as Linux. However, there exists classes of products
where Linux would need to expect services from such a processor or the
delay of Linux and operating system being able to load up such a
firmware is unacceptable.
To address these needs, we need some minimal capability to load such a
system and ensure it is started prior to an Operating System(Linux or
any other) is started up.
NOTE: This is NOT meant to be a solve-all solution, instead, it tries to
address certain class of SoCs and products that need such a solution.
A very simple model is introduced here as part of the initial support
that supports microcontrollers with internal memory (no MMU, no
execution from external memory, or specific image format needs). This
basic framework can then (hopefully) be extensible to other complex SoC
processor support as need be.

Now that we have added MRC cache for Intel FSP and BayTrail codes,
enable it for all BayTrail boards (Bayley Bay and Minnow Max).
Note it turns out that FSP for Intel Atom E6xx does not produce
the HOB for NV storage, so we don't have such functionality on
Intel Crown Bay board.

Instead of creating a rockchip SPL SD card image with 32KB of zeros
which can be written to the start of an SD card, create the images with

The first 32 kilobytes aren't needed for bootup and only serve as
