Yeah, you can do that.

The most important thing is that we can all agree on the same name. Which one we actually choose does not matter that much for me. I would prefer s3c24xx, though, as I've mostly settled for this name now for the things I've done in during the last days. Is there any opposition against this name? Some days ago we also talked to Vince and as far as I understood he did not care that much and would be fine with s3c24xx.

Is there no way we can commit the patches to the build system but not activate it for Debian builds? I would like to avoid having to maintain private patches outside of the d-i repository for a long time. And it will take at least until 2.6.31 is in Debian. It seems that 2.6.31 should have basic support for the Openmoko, but there are still some fixes needed. Unfortunately I couldn't yet find out if they are available somewhere. Gaudenz -- Ever tried.

I think it's fine to apply patches for e.g. libdebian-installer, base-installer, flash-kernel, etc; but you obviously cannot change linux-kernel-di-armel-2.6 and the d-i build system before we have a kernel in the archive. -- Martin Michlmayr http://www.cyrius.com/ -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe".

I propose to name it s3c24xx, are you fine with that name? I'm currently adapting Luca's patch to more closely follow what other arm subarchitectures do. I mainly followed the iop32x example and added an openmoko flavour which will create a network-console uBoot image which should support both GTA01 and GTA02. I hope to submit my patches soon. Do you think that we have to wait committing anything until we have a kernel in the archive?

I think the kernel should ship the normal zImage (like all other ARM kernels) and then you can use uboot-mkimage to generate a bootable kernel during the d-i build process and with flash-kernel. > [PATCH 2/3] linux-kernel-di-armel-2.6: add openmoko-gta02 kernel > > The Debian Linux kernel for the Openmoko GTA02 Neo FreeRunner is not > yet official and thus it does not follow the Debian official kernel > naming (I know this is ugly, sorry).

[PATCH] Basic Openmoko GTA02 support
Hi there!
DebCamp9 hacking produced these patches which add a basic support for
building netboot images for the Openmoko GTA02 Neo FreeRunner.
General notes
=
- You need the Debian unofficial kernel from the pkg-fso repository at
deb http://pkg-fso.alioth.debian.org/debian sid main
Some drivers the official Debian kernels compile as modules are
compiled in in the Openmoko kernel instead, thus I am working on
syncing the latter with the former.
- The d-i files generated in build/dest/openmoko-gta02/netboot/gta02 are
the following:
* rootfs.tar -- root archive for Openmoko GTA02 Neo FreeRunner
This must be decompressed on the microSD. Since there are too many
way to partition the microSD and/or booting, ATM you need to
manually prepare it.
I have not checked the latest GTA02, but in the "old" ones U-Boot
supported booting from an ext2 microSD card with partition 1 as vfat
for /boot. In this case, partition the microSD (8MB vfat + ext2),
decompress root.tar into the ext2 and then copy /boot/uImage$ETC in
/boot/. Since U-Boot usually expects an image named "uImage.bin",
creates the symlink.
* rootfs.jffs2 -- root jffs2 image for Openmoko GTA02 Neo FreeRunner
This must be flashed to mtd6, but it does not work as expected ATM:
$ dfu-util -d 0x1d50:0x5119 -a rootfs -R -D uImage.bin
* uImage.bin -- U-Boot image for Openmoko GTA02 Neo FreeRunner
Nothing more than the U-Boot image shipped by the Debian Openmoko
kernel, again to be flashed to mtd3:
$ dfu-util -d 0x1d50:0x5119 -a kernel -R -D uImage.bin
* flash-debian -- Script to flash debian-installer
This does not work ATM, but the idea is quite simple: the basic
command should prepare the microSD card (partition and everything
needed to decompress rootfs.tar on it) and then have an option to
flash the mtds.

[PATCH 1/3] kernel-wedge: add support for U-Boot uImage.bin
The Debian Linux kernel for the Openmoko GTA02 Neo FreeRunner does not
provide a vmlinuz image, but instead it ships a U-Boot one, thus
kernel-wedge/commands/install-files needs to look for uImage.bin also.
[PATCH 2/3] linux-kernel-di-armel-2.6: add openmoko-gta02 kernel
The Debian Linux kernel for the Openmoko GTA02 Neo FreeRunner is not
yet official and thus it does not follow the Debian official kernel
naming (I know this is ugly, sorry).
NB, there are still some problems with the various modules, which will
be soon corrected. Moreover, hunting down which module are useful and
which not is another thing to do.
[PATCH 3/3] installer: add openmoko-gta02 netboot image
This adds add the basic infrastructure to produce a netboot image.
While cleaning the patch I seems to be unable to produce a correct
netboot image (package ai-choosers not found). I am quite sure that
just after dinner Gaudenz succeded with the same patch (or a very
similar one, just minor modifications). Thus I think it is worth
submitting it now.
I do not think these stuff are at a point for inclusion, but maybe it
would be better for other (hint: Gaudenz) that works on them.
Thx, bye,
Gismo / Luca
