Changes for v5:
- eliminated nonessential code in all files
- changed boardname to conform to "pogo_e02" which is already in kernel mach-type table
- cleaned up GNU license address/URL
- fixed hexadecimal mixed-case in data, a typo and comments in kwbimage.cfg
- minimized GPIO setup in pogo_e02.c
Changes for v4:
- remove parentheses from simple args
- remove erroneous comment and redundant code in config
- remove line wraps
Changes for v3:
- fix ordering mistake in boards.cfg
Changes for v2:
- added MAINTAINERS info for pogoplug_e02
- fixed format to ensure capture of all files in path
