ad5e5c42fb hwstub: fix atj213x dsp lua code

f47f04b65f hwstub: Add ajt213x lua interface for DSP block 
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!

e70ea5d21f hwstub: Add completion and some pretty printing to the shell 
This uses slightly hacked luaprompt to provide all the goodis.
See https://github.com/dpapavas/luaprompt for original.

238be18d03 hwstub: add proper PP support 
- 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
