I have one basic question about the architecture files in Linux
kernels. We have a board with Samsung S3C2510A MCU (ARM940T core)

no-mmu support at the moment" from Ben Dooks.
So, I started developing the architecture files for my Samsung
S3C2510A MCU (ARM940T core) by looking at the existing S3C2410A
(ARM920 core) architecture files. Is this my porting (developing the
architecture files) correct?
How can I port the Linux on to my board which has a Samsung S3C2510A
MCU (ARM940T core) which is a NO-MMU based CPU?
Please suggest me. It would be appreciated your help / suggestions.
I think the uClinux mailing list (CCed) is a more appropriate mailing list for
your questions.
It depends. Any questions regarding the ARM kernel should be on the
arm-linux-kernel (also CCed now), since the nommu support is merged
with the mainline kernel.
uClinux seems to be rather focused on m68knommu (coldfire) these days,
That is more a factor of who shows interest and is active on
the uclinux-dev mailing list more than anything else though.
Quite of few different groups of people interested in non-MMU
ARM platforms have shown up over the years, but none seem to stay
active for long.
and contains both a kernel and user space. The last uClinux release
containst some changes for Samsung platforms (s3c24a0, s3c3410,
s3c44b0x and s5c7375). It's probably a good idea to look at that
code for reference, but I would suggest integrating the code for
your platform in the upstream tree directly.
Yes, highly encourage this.
I could not find a git tree for uClinux that contains any recent
kernel. Does that exist?
I used to keep one on git.kernel.org for promoting non-architectural
but non-MMU specific changes to mainline.
http://git.kernel.org/?p=linux/kernel/git/gerg/uclinux.git;a=summary
But I have had so few changes that fit in that category that I
haven't used it in quite a while.
