Amaury Pouly 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)"

Build Your Own Rockbox

1. Clone 'rockbox' from git (or extract a downloaded archive).

   $ git clone git://git.rockbox.org/rockbox

     or

   $ tar xjf rockbox.tar.bz2

2. Create a build directory, preferably in the same directory as the firmware/
   and apps/ directories. This is where all generated files will be written.

   $ cd rockbox
   $ mkdir build
   $ cd build

3. Make sure you have sh/arm/m68k-elf-gcc and siblings in the PATH. Make sure
   that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
   a particular version depending on what player you are compiling for. These
   can be acquired with the rockboxdev.sh script in the /tools/ folder of the
   source, or will have been included if you've installed one of the
   toolchains or development environments provided at http://www.rockbox.org/

   $ which sh-elf-gcc
   $ which perl

4. In your build directory, run the 'tools/configure' script and enter what
   target you want to build for and if you want a debug version or not (and a
   few more questions). It'll prompt you. The debug version is for making a
   gdb version out of it. It is only useful if you run gdb towards your target
   Archos.

   $ ../tools/configure

5. *ploink*. Now you have got a Makefile generated for you.

6. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make
   $ make zip

7. unzip the rockbox.zip on your music player, reboot it and
   *smile*.

If you want to build for more than one target, just create several build
directories and create a setup for each target:

   $ mkdir build-fmrecorder
   $ cd build-fmrecorder
   $ ../tools/configure

   $ mkdir build-player
   $ cd build-player
   $ ../tools/configure
