Hi,

If "silent" env variable is set GD_FLG_SILENT is added to gd->flags (in console_init_f). That effectively causes all console output to be suppresed. That flag also causes nulldev to become outputdev (in console_init_r). Btw, shouldn't CONFIG_SILENT_CONSOLE depend on CFG_DEVICE_NULLDEV in this case? Now we are entering into abortboot (CONFIG_AUTOBOOT_KEYED) and because "silent" env variable is set and also CONFIG_SILENT_CONSOLE defined console_assign (stdout, "serial"); is called, doing basicaly nothing, because GD_FLG_SILENT which is still set prevents any console output.

There are various solutions from this situation, but I'd like first understand what is CFG_DEVICE_NULLDEV good for when we have GD_FLG_SILENT? Or better, how should all these three things in question behave?

thanks, ladis
