fdb98c258f hwstub/jz4760b: add lua code to probe for ei/di and ext instructions
Add lua code to check whether ei/di and ext instructions are supported. This
is unclear since xburst is somewhere between mips32r1 and mips32r2. Details
results are below, but in summary: they don't work (ei has no effect, di/ext
cause illegal instruction exceptions)

> ./hwstub_shell -q -b -e 'require("jz/misc"); JZ.misc.enable_sram()' \
  -f lua/xburst.lua -e "XBURST.test_ext_inst(0xb32d0000)"

8e07d68452 hwstub: add various jz stuff and xburst tests
The JZ misc allows to enable and test SRAM.
The XBurst code uses the coprocessor interface to analyse the cpu. It also
provides a test platform for various features like EBASE and exceptions.
I was able to test and confirm that on jz4760b (thus xburst), EBASE works
(but top 2 bits are not controllable and always 01). The processor claims
to support vector interrupts but this is untested. The values in ConfigX
are not to be trusted blindly, clearly some are wrong. I tried to use the
JZ4780 Config7 "ebase gate" to change bit 30 of EBASE but it does not work,
which suggests that JZ480 uses a newer version of XBurst. Detailled log below:

> ./hwstub_shell -q -f lua/xburst.lua -e "XBURST.init()"

4fd9400458 hwstub/tools/shell: add JZ4760B and Fiio X1 code
The jz code can do several useful things like dumping the IPL and SPL.
The Fiio code can play with backlight and has code do dump the IPL
and SPL with the correct parameters (extracted by reverse engineering).

f6c61eb11a hwstub: port hwstub_shell to the new library
Also use this opportunity to cleanup support for multiple devices: the shell
now supports dynamic changes in the device and will call init() everytime
a new device is selected, to prepare a new environment. The shell now
honors register width on register read/write. The shell also provides access
to variants as follows by creating a subtable under the register using the
variant type in UPPER case and having the same layout as a register.
For example if register HW.GPIO.DIR has variants "set" and "clr", those can
be used like this:
HW.GPIO.DIR.SET.write(0xff)
HW.GPIO.DIR.CLR.write(0xff00)

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!

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
