Exception: scripts sourcing/calls within etc/ash_functions continues to use old TRACE functions until we switch to bash completely getting rid of ash. This would mean getting rid of legacy boards (flash + legacy boards which do not have enough space for bash in flash boards) once and for all. Signed-off-by: Thierry Laurion <insurgo@riseup.net>
