[U-Boot] [RFC 1/2 v2] cmd: Remove CONFIG_SYS_MAXARGS
John Schmoller
jschmoller at xes-inc.com
Fri Mar 12 20:25:30 CET 2010
CONFIG_SYS_MAXARGS is an arbitrary limit on the number of arguments
which can be input at the command line. Remove that arbitrary limit.
Setting maxargs in the cmdtp to 0 will result in the ability to enter
as many arguments as you can hold in CONFIG_SYS_CBSIZE.
Signed-off-by: John Schmoller <jschmoller at xes-inc.com>

Since v1:
- Moved a change from 2/2 to this patch so both compile cleanly independently.
