/*
* Peripheral Mapping Table (PMT) definitions
*
* Each entry in this table holds the physical address of a section of peripherals
* and the tag for the type of peripherals in that section.
* Peripherals of the same type go into the same section, which is subdivided
* as appropriate for that peripheral type.
* Each section is at least 64KB wide, each subdivision is at least 4KB wide.
*
* NB: This table grows *down* from the top of the address space
* The value 0xffffffff for an entry indicates the section is not populated.
* The tag 0xffff is therefore invalid.
* The end-of-table is indicated by the first invalid entry.
*
* Entries in the table are (preferably) in the processor's own byteorder.
* The first entry is for the table itself and has a known tag.
* From this software can verify the byteorder is correct.
*
* For each section we also define here its favorite placement in the address space.
* Software should verify the table for the ultimate truth, peripherals might
* or might not be present in the FPGA bitfile being used.
