Update to 4.1.7

From GreenphoneWiki

Simply download and install the 4.1.7 SDK, execute sudo /opt/Qtopia/extras/bin/usbflash /opt/Qtopia/extras/images/qtopia-greenphone-flash and follow the instructions.

qtopia-greenphone-flash-4.1.7 is a .tar.gz file consisting of flash.conf, zImage_Truly_Trolltech and greenphone_root_prg_FS.ext2. The file flash.conf contains besides the filenames and their checksums (MD5) 2 for the kernel and 3 for the root filesystem. Those numbers possibly stand for the part in flash used for them.

The file greenphone_root_prg_FS.ext2 contains the root file system which resides in /dev/root = /dev/tffsa. It does not seem to contain any of the things stored in /dev/tffsb to /dev/tffsd. The test, if the numbers 4 to 6 overwrite the stuff in those areas, is still standing out.

The zImage consists of the kernel itself and an ext2 file system containing tffs.o (the TrueFFS module) and linuxrc which basically loads tffs.o and switches to the final root filesystem. This is given as an argument to the kernel as root=6400 which possibly stands for major 100 (=64 hex) and minor 0, resulting in /dev/tffsa.
