[PATCH] board: tbs2910: Add support for generic distro configuration

[Soeren Moch]

Hi Denis,

thanks for your patch. In general I think it could be a good idea to
support distroboot on this board, especially if we can maintain
compatibility with the existing boot procedure. However, since this
board repeatedly has size problems with the u-boot binary, we carefully
need to check binary size.
More questions inline.

Why do you define CONFIG_BOOTCOMMAND here instead of modifying the
existing one?

There in no SPL for tbs2910. So this is not required.

This should not be defined. Usually we want to relocate the initrd.
