Add a sort of batch mode to fw_setenv, allowing to set multiple variables in one shot, without updating the flash after each set as now. It is added the possibility to pass a config file with a list of pairs <variable, value> to be set, separated by a TAB character. Signed-off-by: Stefano Babic <sbabic@denx.de>
