Michael Giacomelli 49b4d8f2c9 test_cyc: AS3525v2 cache and write testing
The rows that calibrated the Clip+ model in utils/perfsim, timed on
AS3525v2 with the tick timer's count for a 2/3 microsecond clock:

  - calls, returns and loads into pc, interlocks after a load and
    after a multiply, multiplies by operand size
  - a miss with work after it, on each word of its line, back to
    back, and evicting a dirty line; a load or store to the line
    still filling
  - stores to lines not cached: one stream, a word a line, four
    words at a time, two streams turn about
  - copies between uncached buffers, within a memory and across
  - fetch misses in code written where it runs
  - loops of adds and of branches by how many lines they cover, and
    a cached pointer chase likewise
  - the TTA filter stage by stage and Tremor's window loop

On AS3525v2 the miss rows run in DRAM and again in the RAM inside
the SoC, where codecs are loaded.

Rows that turned out to say nothing, or that a later row replaced,
stay in the file under TEST_CYC_ARCHIVE, each with why.
TEST_CYC_QUICK runs only the newest rows.

With these rows the plugin is about 140 KB on ARMv5, so it is left
out where the plugin buffer is 128 KB or less: the Clip, the m200v4
and the c200v2.

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.xz

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 mips/m68k/arm-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 generated using the rockboxdev.sh script in the /tools/ folder of the
   source.

   $ which arm-elf-eabi-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-fuzeplus
   $ cd build-fuzeplus
   $ ../tools/configure

   $ mkdir build-xduoox3
   $ cd build-xduoox3
   $ ../tools/configure
