Title: Please add support for the medion NAND, icluding original partiton scheme...

This allows easy accessing the orignal uBoot environment stored in the NAND via userspace u-boot-tools, so no need for UART access for changing the environment.
I'd definitely prefer using that environment in common for both the stock firmware in NAND (which btw I could access after adding yaffs2 support to the kernel via MTD block device, just as the original firware does) and the u-Boot on the HDD, for a sort of multi-boot setup, changeable from userspace without UART access.
If later, uBoot could handle the OTC-Button as well as LEDs or the beeper, at least a dual-boot possibility via Button and a certain timeout in which the button can be pressed could be imagined as well...
