Dropping board files would be a nice step but only a half-way, because
we could not remove the S3C support from the drivers.

The platform to stay should have either:
1. real users in the production who need updates
or
2. hackers who have hardware, like to play with it and will do the
testing/development.

In the second case (the hackers) having only the hardware but not
testing or running newest kernels does not revive the platform from the
almost-dead stage.


Best regards,
Krzysztof
