With this you can upload and run code on DSP core in atj213x.
The files can be produced using as2181. You can download
this assembler from https://github.com/wodz/as2181
You should use extended mode (-x switch) since DSP core
in atj is non standard and uses 24bit operands.
PX register has different meaning as well and is used as MSB
when loading other registers with immediates (immediate field
is 16bit in instruction so to set register to 24bit value
you need to store MSB in PX prior to this).
MAC MR is 56bit accordingly.
HIP interface seems to be mapped at standard addresses
(except that regular 218x doesn't have HIP).
Have a fun!

This uses slightly hacked luaprompt to provide all the goodis.
See https://github.com/dpapavas/luaprompt for original.

The current code assumed that READ/WRITE would produce atomic read/writes for
8/16/32-bit words, which in turned put assumption on the memcpy function.
Since some memcpy implementation do not always guarantee such strong assumption,
introduce two new operation READ/WRITE_ATOMIC which provide the necessary
tools to do correct read and write to register in a single memory access.

- drop support for PP500x: it's very different from other PP and although
it would be possible to support them, I don't have one to test the code
- make sure only the CPU is started
- add PP descriptor to report chip ID and revision
- add code in shell and lua to support pp (no register description yet)
- compile for ARMv4 because PP502x is an ARM7TDMI

A SoC descriptor is not a small object: it can be as large as ~100KiB so
it's better to avoid copying things over.

The protocol has evolved a lot during the 2.x.y lifetime, bringing more
features which later got unused. This commit removes all the unused stuff
and simplifies everything:
- drop the feature mask: everything is mandatory or stalled on error
- remove the info request and put all static information in standard USB
descriptors which are part of the configuration descriptor (and can be
retrieved using the standard GetDescriptor request).
- remove the USB interface, we had only one anyway
- remove all endpoint descriptors
- remove the exit/atexit stuff, it never worked as intended anyway
- update the hwstub library and make it able to handle any device
- update the tools (mostly renaming and removing of code)

Fix the stub in many way to correctly detect the STMP family and
act upon that. Drop some unused commands and bump version.
Rewrite the tool to allows scripting in lua and load the register
description from an XML file using the regtools. Introduce a new
tool to load and run code using the hwstub (either binary format
or Rockbox additive scramble format). Also switch to an optimise
version of the memcpy/move/set functions to correctly handle
alignement issue (like writing a full word/half-word when
possible for registers which is crucial)

The hwemul is only partly imx specific: the stub is stmp specific
but could be ported to other targets, the computer side and the
protocol are mostly stmp independent (or should be).
