The board has an ethernet interface, so enable DHCP for it.
The used flash chip uses 16K erase blocks, so use that for JFFS2:
Eraseblock size: 16384 bytes, 16.0 KiB
Amount of eraseblocks: 1915 (31375360 bytes, 29.9 MiB)
Minimum input/output unit size: 512 bytes
Sub-page size: 256 bytes
OOB size: 16 bytes
Character device major/minor: 90:10
Bad blocks are allowed: true
Device is writable: true
While we're at it, add a readme explaining how to build and upload the build
to the board.
