This patch adds support for Cloud Engines Pogoplug E02

Information regarding the CE Pogoplug E02 board can be found at: http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray

Signed-off-by: Dave Purdy david.c.purdy@gmail.com Cc: prafulla@marvell.com Cc: albert.u.boot@aribaud.net --- 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
