This patchset adds support for both the Linkstation Live (LS-CHLv2) and
Linkstation Pro (LS-XHL) by Buffalo.

v2:
 - add to buffalo vendor directory instead of Marvell
 - add both boards to MAINTAINERS
 - don't define values for feature macros
 - use tab for vertical alignment
 - remove static network configuration, instead introduce a rescue mode
 - add some convenience scripts
 - small cleanups
