This patch series add support for new board Nokia RX-51 (aka N900). Last two patches adding on screen bootmenu support.
This series supersedes the last sent version.
A quick offtopic question - how do you replace boot loader on N900?
Thanks a lot, S.
See commit message in: [PATCH 12/14] New board support: Nokia RX-51 aka N900
Bootloader is not replacing (yet). Instead U-Boot is flashed into kernel area and loaded by proprietary NOLO bootloader. NOLO can load only one image and only from kernel area - so it does not support dualbooting.
So why not just replace the bootloader right away?
Kernel image can be attached into U-Boot binary (at pos. 0x40000) and flashed into nand kernel area (2MB is enought for U-Boot with kernel). And then U-Boot can boot attached kernel image or load/boot it from SD/eMMC.
