No, you don't need a RAM-disk. U-Boot can directly boot from a flash
partition (for example a cramfs or JFFS2 partition).

In embedded applications you normally _know_ which hardware you have, so
either compile it directly into the kernel or load your module from a
script while starting.

Initrds were invented for distributors; they normally don't know which
hardware the user boots on, but have to supply drivers for every
possible device.
