So it should be that much work to add Nokia N900 support? Apart from this it should be easy to add support for the Beagleboard or Pandaboard, since they very similar to a normal PC, but I don't own them ;) Pandaboard (OMAP4) and BeagleBoard (OMAP3) based devices boot off SD/MMC card, in the case of Pandaboard it only boots off SD/MMC (no MTD device available). debian-installer does not have support for MTD devices due to parted not supporting it (#487738), but some improvements have been done and bitrot [0]. So, basically, what debian-installer needs to add to support such devices (taking in account debian-installer runs native)? Maybe a cross installer which puts together a kernel + rootfs in a cross way is more than enough. I am currently cooking out one for my purposes (#604834), but it is not ready yet. In anycase, if anyone takes the lead to add support for OMAP into d-i and kernel, I am available to help and test it out.

Yes, that the reason why I named the config -omap and not -n900 or -omap3 :) The configuration, which I linked to [0], does not touch the board configuration - they are all enabled by default :) I think OMAP would be a reasonable addition to the Debian kernel since there are a lot of devices. Yes, there are lot's of smartphones today and there will come more, because omap4 is also supported by the kernel :) However, personally I'd like to see explicit support for some OMAP devices in Debian installer, otherwise I don't see a lot of value in providing a kernel.

Would it be acceptable to add the tsc2005 driver as patch until it hits mainline [1]?

I would really like to use the forthcoming support for Device Trees to limit the number of different ARM kernel images we need to build. We would presumably need to rework the definition of 'flavours' so multiple flavours could use the same kernel images and different DTs.
