[PATCH 1/3] cmd: bdinfo: provide long help with all options

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

Document the bdinfo -a, -e and -m options in the long help, but only
when they can be used. The string concatenation is a bit odd with two
newlines, but it does render properly once in U-Boot CLI.
