OpenWrt Target for Android (Samsung Galaxy Tab)
===============================================

Note: very first alpha version - needs improvement

* Run programs compiled with the OpenWrt toolchain on the SGT.
* You can install in /data/local on SGT (no root required)
* You can compile yourself (e.g. if you miss a package)

Installation requires that you can run adb (Android Debugging
Brige program via USB) or at least have the ConnectBot app:

1) Mount internal SD-Card to your PC
2) Unpack data-local.tgz on SD, e.g. to ./bla/
3) Remount internal SD-Card on SGT
4) Call up local shell (no root required)
5) > cd /data/local
6) > cp -a /sdcard/bla/* .
7) > exec /data/local/bin/busybox ash --login

Currently included: openvpn, mtr, tcpdump, ip, tc, iptables, ip6tables
strace, iwconfig, olsrd, horst, busybox, and a etc/profile with some
aliases and env settings. Note: ncurses does not work (TERM missing)

Compile on you PC:

1) Setup OpenWrt Toolchain (see http://wiki.openwrt.org/doc/howto/build)
   > svn co svn://svn.openwrt.org/openwrt/branches/backfire
   > cd backfire
   > ./scripts/feeds update -a
   > ./scripts/feeds install -a

2) Unpack new target: 
   > tar xvzf /tmp/backfire-sgt.tgz
   Note: kernel patches from opensource.samsung.com/sgt download

3) Patch some things
   > patch -p1 < target/linux/sgt/sgt-openwrt-buildroot.patch

4) Configure the beast
   > cp target/linux/sgt/sgt-openwrt-config .config
   > make menuconfig
   (Change options if you like, save new config)

5) Compile
   > make V=99 -j 2

If you have e.g. a new package, you'll find the below bin/sgt/packages/*.ipk.
Those can be unpacked with tar, e.g. "tar xvzf mtd*.tgz". The "data.tar.gz"
in that ipk can be unpacked below /data/local on the SGT.
