Considered stable enough for production

There remain only two known issues. The first is that the read-modify-write cycle is not honoured for TT-RAM and the second is that a reset causes the SDRAM controller to re-initialise which may lose memory during the period in which there are no refreshes.

There is another limitation with this release which is that whilst it supports either a 512k or 1M Flash chip, only a maximum of 512k is currently useable.

These are considered minor enough a drawbacks for me to name this version 1.0.

DFB1 v0.1 BETA

This is the first public release of production files with two working boards built by the author from these files.

Feedback appreciated.

Source is potentially ahead of these, but may not be thoroughly tested. These are intended to be stable.
