Subject: tools, fit_info: increase buffer for command name
X-Git-Tag: v2014.10-rc2~82^2~7
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=686dca0fc4eb077b089c7507f899097d001c8ce3;p=u-boot

tools, fit_info: increase buffer for command name

currently the buffer for command name is 50 bytes only. If using
fit_info with long absolute paths, this is not enough, so raise
it to 256 (as it is in fit_check_sign)
