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.

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}.

So far VxWorks bootline can be contructed from various environment
variables, but when these variables do not exist we get these from
corresponding config macros. This is not helpful as it requires
rebuilding U-Boot, and to make sure these config macros take effect
we should not have these environment variables. This is a little
bit complex and confusing.
Now we change the logic to always contruct the bootline from
environments (the only single source), by adding two new variables
"bootdev" and "othbootargs", and adding some comments about network
related settings mentioning they are optional. The doc about the
bootline handling is also updated.

We run 4 Arndale boards in our automated test framework, they have
been running quite happily for quite some time using a Debian Wheezy
userspace.
However when upgrading to a Debian Jessie we started seeing frequent
segmentation faults from gcc when building the kernel, to the extent
that it is unable to successfully build the kernel twice in a row, and
often fails on the first attempt.
Searching around I found https://bugs.launchpad.net/arndale/+bug/1081417
which pointed towards http://www.spinics.net/lists/kvm-arm/msg03723.html
and CPU Errata 773022 and 774769.
This errata needs to be applied to all processors in an SMP system,
meaning that the usual strategy of applying them in
arch/arm/cpu/armv7/start.S is not appropriate (since that applies to
the boot processor only). Instead we apply these errata in the secure
monitor which is code that is traversed by all processors as they are
brought up.
The net affect on Arndale is that ACTLR changes from 0x40 to
0x2000042. I ran 17 kernel compile iterations overnight with no
segfaults.
Runtime testing was done on our v2014.10 based branch and forward
ported (with only minimal and trivial contextual conflicts) to current
master, where it has been build tested only.
I suppose in theory these errata apply to any Exynos5250 based boards,
but Arndale is the only one I have access to and I have therefore
chosen to be conservative and only apply it there.
Also, reorder CONFIG_ARM_ERRATA_794072 in README to make the list
numerically sorted.
