Sega megadrive gamepad driver for raspberry pi gpio

1. Get running kernel sources

  * find pi firmware git hash:

  ```bash

  zcat /usr/share/doc/raspberrypi-bootloader/changelog.Debian.gz | head

  ```

  * find pi kernel sources git hash:

  ```

  firmware/extra/git_hash

  ```

  * get pi kernel sources

  * setup KERNEL_SRC environment variable:

  ```bash

  export KERNEL_SRC={path-to-kernel-sources}

  ```

  * get Module.symvers from firmware repo:

  ```bash

  cp firmware/extra/Module.symvers ${KERNEL_SRC}

  ```

2. Get running kernel config

  * ensure configs module running:

  ```bash

  modprobe configs

  ```

  * get running kernel config:

  ```bash

  zcat /proc/config.gz > ${KERNEL_SRC}/.config

  ```

3. Setup compiler tools

  * setup CCPREFIX environment variable:

  ```bash

  export CCPREFIX=/{tools-path}/arm-bcm2708/{compiler-path}/bin/arm-linux-gnueabihf-

  ```

  * prepare kernel sources:

  ```bash

  make ARCH=arm CROSS_COMPILE=${CCPREFIX} oldconfig

  make ARCH=arm CROSS_COMPILE=${CCPREFIX} modules_prepare

  ```

4. Build module

  * run make within pijoy module directory:

  ```bash

  make ARCH=arm CROSS_COMPILE=${CCPREFIX} -C ${KERNEL_SRC} M=$(pwd)

  ```

5. Upload and run compiled module

  * upload module to pi:

  ```bash

  scp pijoy.ko pi@raspberry:/home/pi/

  ```

  * install module on pi:

  ```bash

  mv /home/pi/pijoy.ko /lib/modules/$(uname -r)/

  ```

  * load module on pi:

  ```bash

  modprobe pijoy dev1=0,6

  ```
