Declaration ROM

To make use of the Slot Manager for hardware probing, interrupts, etc. we need to do two things:

• Map our device into a memory region corresponding to a NuBus slot (on the SE/30, valid 'pseudoslots' are 9, A, or B).

• Have a declaration ROM header at the very end of the slot's address space, pointing to a valid sResource directory.

This directory contains a suitable declaration ROM laid out in GNU Assembler format, with a Python script to perform some basic validity checks and post-processing.
