The U-Boot patches to support the N900 are mainlined, but the fancy bootmenu is still missing: [http://lists.denx.de/pipermail/u-boot/2013-February/145719.html PATCH v3: ANSI terminal Bootmenu].

Kernel git repository for N900

There is git repository for upstream linux kernel with all N900 patches.

https://gitorious.org/linux-n900/linux-n900

This git repository is used for development. All other git repositories on internet are older and does not contains all patches.

U-Boot

Instead of booting the kernel directly from NOLO (which restricts you to using exactly one kernel), U-Boot can be used as second bootloader. The Maemo kernel can be appended to U-Boot to keep the existing Maemo installation working (U-Boot must be located at the location of the Maemo kernel). The resulting boot process will end up like this: NOLO -> U-Boot -> Kernel.

Pali Rohár has been working on getting the N900 support into the mainline U-Boot:

description date status
Board Support 2012-10-29 mainline
Bootmenu Support 2013-03-07 mainline

Currently all U-Boot development for the Nokia N900 is done in this git repository: https://gitorious.org/u-boot-shr/u-boot (branch pali).

There's also a thread on talk.maemo.org, where the latest released & tested version can be found: http://talk.maemo.org/showthread.php?t=81613

Flashing

There is open source flasher application 0xFFFF which working with Nokia N900. Git repository is on: https://gitorious.org/0xffff/0xffff
