31  * Notes on register naming:
32  *
33  * Fujitsu documents for MB86960A/MB86965A uses no mnemorable names
34  * for their registers.  They defined only three names for 32
35  * registers and appended numbers to distinguish registers of
36  * same name.  Surprisingly, the numbers represent I/O address
37  * offsets of the registers from the base addresses, and their
38  * names correspond to the "bank" the registers are allocated.
39  * All this means that, for example, to say "read DLCR8" has no more
40  * than to say "read a register at offset 8 on bank DLCR."
41  *
42  * The following definitions may look silly, but that's what Fujitsu
43  * did, and it is necessary to know these names to read Fujitsu
44  * documents..
