Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

15 | * GIO bus addresses | ||
16 | * | ||
17 | * The Indigo and Indy have two GIO bus connectors. Indigo2 (all models) have | ||
18 | * three physical connectors, but only two slots, GFX and EXP0. | ||
19 | * | ||
20 | * There is 10MB of GIO address space for GIO64 slot devices | ||
21 | * slot# slot type address range size | ||
22 | * ----- --------- ----------------------- ----- | ||

24 | * 1 EXP0 0x1f400000 - 0x1f5fffff 2MB | ||
25 | * 2 EXP1 0x1f600000 - 0x1f9fffff 4MB | ||
26 | * | ||
27 | * There are un-slotted devices, HPC, I/O and misc devices, which are grouped | ||
28 | * into the HPC address space. | ||

34 | * GIO bus IDs | ||
35 | * | ||
36 | * Each GIO bus device identifies itself to the system by answering a | ||
37 | * read with an "ID" value. IDs are either 8 or 32 bits long. IDs less | ||
38 | * than 128 are 8 bits long, with the most significant 24 bits read from | ||
39 | * the slot undefined. | ||
40 | * | ||
41 | * 32-bit IDs are divided into | ||
42 | * bits 0:6 the product ID; ranges from 0x00 to 0x7F. | ||
43 | * bit 7 0=GIO Product ID is 8 bits wide | ||
44 | * 1=GIO Product ID is 32 bits wide. | ||
45 | * bits 8:15 manufacturer version for the product. | ||
46 | * bit 16 0=GIO32 and GIO32-bis, 1=GIO64. | ||
47 | * bit 17 0=no ROM present | ||
48 | * 1=ROM present on this board AND next three words | ||
49 | * space define the ROM. | ||
50 | * bits 18:31 up to manufacturer. | ||
