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..
