[Openocd-development] making the target scripts a bit less verbose

[Øyvind Harboe]

Which is better? (whatever "better" is)

This:

if {[info exists CHIPNAME]} {
   set  _CHIPNAME $CHIPNAME
} else {
   set  _CHIPNAME at91r40008
}

or this:

set _CHIPNAME [defaultval $CHIPNAME at91r40008]


# Std proc to be added
proc defaultval {varname defval} {
    if {[uplevel "info exists $varname"]} {
        return $varname
    } else {
        return $defval
    }
}
