Hi Scott,

When an IP block can be shared among several different architectures, where should the _header_ files be located?

Examples of such blocks would be OpenCores peripherals, Altera peripherals, etc.

Some peripherals may not need to export any interfaces, so no header file is necessary. But this certainly is not the case for all peripherals.

Any precedents, comments, suggestions?

Linux is always a good precedent, so checking there should give us a clue.

Apart from that I'd go for include/device-type/... Names of manufacturers change _way_ too often :)

Cheers Detlev
