Hi there,
The Embedded Artists has a board based on ARM LPC3250 called EA3250 and
they provide a BSP with patch to Linux Kernel version 2.6.29.2. I am trying
to "up merge" this patch to Kernel v3.4 (now 3.5) and after that get it in
the mainstream. Although I have a working version (
https://github.com/jrbenito/Kernel-LPC3250) I still have doubts on how to
correct submit it to mainline kernel.
-The machine type is already registered in past (
http://www.arm.linux.org.uk/developer/machines/list.php?id=2512) but it is
not in mainline. Since I shall not patch this file, how can I ask to it be
updated with ea3250 board information?
-Could you please point me any documentation on how to add board support to
Linux Kernel?
My doubts are mainly related with process and order of files to submit I
shall follow. Any direction will be strongly appreciated.
Thanks and best regards,

Sorry for the late reply, I was just going through old unread email.
The lpc32xx platform is getting converted to device tree based probing,
which means your board will have to use a device tree file rather than
a board number anyway, which at least solves the problem of getting back
the assigned board number entry.

Please have a look at the phy3250 support in arch/arm/boot/dts/phy3250.dts
and at the files in Documentation/devicetree.
There are still a few bits missing device tree bindings, in particular the
display and the DMA engine, but you can start with a device tree file
that describes everything else.

We already have ea3250.dts in mainline since v3.5.
