Has anyone tried to boot the linux-next in the mini2440 boards? I have tried with mini2440_defconfig and it is not even booting. I posted the problem in the forum of friendlyarm (http://www.friendlyarm.net/forum/topic/6076) but the only answer i got is we need to a number of patch to make the mainline kernel boot into mini2440. Well , Ok , I can prepare the patch but my question is if mini2440_defcofconfig is there in the mainline kernel , that means it has been properly tested before adding , and that only means that I must be doing some mistake and thats why its not booting.

I think there are no formal rules for what constitutes a proper defconfig file. "Allows to boot the targeted hardware" seems a reasonable demand to make, especially for rather specific targets such as a single ARM board.

From the short discussion on the forum you linked to I get the impression that the code that currently is in mainline simply will not boot a mini2440. (This makes discussing the merits of its defconfig file rather pointless.)

So, apparently, someone should either: try to submit the needed patches for mainline; or request to drop the non-working mini2440 support from mainline (as it is now tricking people into thinking mini2440 is properly supported). I have no idea whether proper support for mini2440 boards is actually a realistic goal. I know nothing about these boards. You're probably better of discussing that with the names that show up if you do scripts/get_maintainer.pl -f arch/arm/mach-s3c24xx/mach-mini2440.c Paul Bolle
