[U-Boot] [PATCH 02/31] environment, netconsole: reducing packages when printing environment variables

[Heiko Schocher]

Actual, do_printenv () uses putc () to print the Environment-
variables. If using netconsole, this will result in a lot of
packages with single characters in it. With the new config
option CONFIG_ENV_BUFFER_PRINT do_printenv () uses now puts ()
to print a complete Environmentvariable, so the number of
packages when using netconsole are reduced.
