sdb hardware information: the data

The directory hwinfo-sdb/ includes the "source", trivially written by hand. The "hwinfo" file is just a bunch of 0xff bytes. The final file will be a tagged format. binaries/sdb-for-dataflash is the one that is going to be edited at build/install time -- in theory only by the manufacturer. I generated it running the command sdbfs/userspace/gensdbfs hwinfo-sdb binaries/sdb-for-dataflash from within a checkout of fpga-config-space (another ohwr project, the SDB home). The default mac addresses match what we used so far: 02:34:56:78:9A:BC and 02:34:56:78:9A:00 for the WR ports. The file names ("eth0.ethaddr") are there so to use a generic setting approach in barebox. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
