37 * Notes on register naming:
38 *
39 * Fujitsu documents for MB86960A/MB86965A use no mnemonic names
40 * for their registers. They defined only three names for 32
41 * registers and appended numbers to distinguish registers of
42 * same name. Surprisingly, the numbers represent I/O address
43 * offsets of the registers from the base addresses, and their
44 * names correspond to the "bank" the registers are allocated.
45 * All this means that, for example, to say "read DLCR8" has no more
46 * than to say "read a register at offset 8 on bank DLCR."
47 *
48 * The following definitions may look silly, but that's what Fujitsu
49 * did, and it is necessary to know these names to read Fujitsu
50 * documents..
