- It's somewhere between MegaSTe and TT. The clock sources and frequencies
- are the same as for the MegaSTe, the DMA chip supports SCC channel A as in
- the TT.

- A driver for SCC channel A using DMA would be almost the same for TT and
- Falcon. For channel B one driver will do for Falcon, MegaSTe and TT.
