Subject: command: Use a constant pointer for the help
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=6b03448713c20dd71ab6cc8e2c1c326db0148169;p=u-boot.git

command: Use a constant pointer for the help

This text should never change during execution, so it makes sense to
use a const char * so that it can be declared as const in the code.
Update struct cmd_tbl with a const char * pointer for 'help'.

We cannot make usage const because of the bmode command, used on mx53ppd
for example.
