this commit is a combination of the following changes, which significantly refactors usb core and class drivers. 1. unify usb buffers of each class driver to reduce iram usage currently, many class drivers allocate their own buffer to receive control out data, which is a waste of iram. share one common buffer for that usage to address the issue. 2. simplify control request handling by implicitly receiving write request data packets change 1 above fixed the data destination. therefore, having the core receive the data allows us to reduce the class driver's work and simplifies the api. 3. enhance usb core's control request handling and unify the legacy driver api in order to implement change 2, both the legacy and new driver apis should be supported. so that, using the designware driver as a reference, the new driver api functionality is move into usb core. this simplifies the usb device drivers by requiring them to implement only the functionalities equivalent to the legacy api. tested with ipodvideo(arc) and erosqnative(designware) Change-Id: I3627daa90278751f599e2108ec150ec3f8f6c524 |

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
