This is not really helpful. Board type is not going to change after the boot, so it's sufficient to print the warning only once. Signed-off-by: Aaro Koskinen <firstname.lastname@example.org>I don't think we need this patch. In 2/2 you add the board type for the board you have, so you shouldn't be getting any messages, and this is unneeded. I don't mind spamming people with all the messages, if people see these messages, they have bigger problems than too many messages.I guess this patch can be dropped, but whoever tries to improve the support for the next new Octeon board will get annoyed by these same messages...I would hope that the "next new Octeon board" would have a bootloader that supplies a device tree. That way most of this would never be used, and there would be no messages.Yes, actually I was wondering if MIPS kernel could offer something similar to ARM's APPENDED_DTB, i.e. provide some mechanism to pass the dtb if the bootloader support is missing.
Well the octeon port does supply its own device tree if one isn't passed from the bootloader. And your patch 2/2 supplies the information used populate it.
But that is not quite the same I think. It would be nice to be able to pass on the command line something. Then you could load a blob from the boot ROM or similar and get something sensible.
