hi,
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. So can
anyone give any pointer to how i can make the linux-next boot on a
mini2440 board ? the filesystem is the default filesystem given by the
friendlyarm guys.

Thanks
Sudip

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
