I've given some thought on how users can figure out if a part
is supported by OpenOCD.
There are thousands of flash/target types & combinations out there.
The user may have the part number or some other string to describe
his flash or target.
There are two things that I'd like to see:
- the user should have an effective means to answer if flash X or target Y
is supported and the status of that support.
- it should be possible to print out an exhaustive human readable description
of flash & target support. This information may have to be generated to
cover combinations or sequences of part numbers...
Attach is the change in the flash driver interface that I have in mind.
In addition there needs to be code to support this and some new
commands to run queries + ditto for the target interface...
