This patch implements a simple API to use the external interrupt hardware present on s5l8702 (GPIO interrupt controller). This GPIOIC has been fully tested using emcore apps. Code is based on openiBoot project, there are a few modifications to optimize space considering we will only use two or three external interrupts. The API compiles and works, but has been never used, therefore probably will need some changes to the final version. External interrupts are necessary for jack remote+mic controller (see iAP Interface Specifiction: Headphone Remote and Mic System), this controller is located at I2C bus address 0x72, there is a IRQ line for remote button press/release events routed to GPIO E6. At this moment, the functionallity of this controller has been extensively tested using emcore, getting a lot of information about how it works. Microphone is already working on RB, jack accessory detection and button events are work in progress. PMU IRQ line is also routed to GPIO F3, it signals many events: holdswitch, usb plug, wall adapter, low battery... The use of PMU interrupts is the orthodox way of doing things, at this moment there is no work done in this direction, there are a lot of PMU events and i think it is a matter of discursion what to do and how.

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
