If CONFIG_SYS_MALLOC_F_LEN is enabled, the stack is moved down to the
specified size to make the malloc function available before relocation.
But on keystone platforms SYS_SPL_MALLOC is immediately preceding stack,
which is causing an overlap with this config enabled.
So leave a gap between malloc space and stack space.

Introduce a dummy driver for sandbox that allows us to verify basic
functionality. This is not meant to do anything functional - but is
more or less meant as a framework plumbing debug helper.

The sandbox remoteproc driver maintains absolutey no states and is a
simple driver which just is filled with empty hooks. Idea being to give
an approximate idea to implement own remoteproc driver using this as a
template.

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.

* SD card (legacy boot)
* EMMC (standard distro boot)
* EMMC (legacy boot)
* Nand (legacy boot)

Hush has an oddity where using ${var} causes var to resolved in the the global
address space (iotw the environment) first and only afterwards will the local
variable space be searched.

This causes odd side-effects when iterating over the boot partitions
using ${bootpart} if the environment also has a bootpart variable (e.g. for
the various TI boards). Fix this by using the hopefully more unique
${distro_bootpart} instead of ${bootpart}.
