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!

20 * The MV64360 has 2 PCI buses each with 1 window from the CPU bus to
21 * PCI I/O space and 4 windows from the CPU bus to PCI MEM space.
22 * We'll only use one PCI MEM window on each PCI bus.
23 *
24 * This is the CPU physical memory map (windows must be at least 64K and start
25 * on a boundary that is a multiple of the window size):

27 * 0x80000000-0x8fffffff - PCI 0 MEM
28 * 0xa0000000-0xafffffff - PCI 1 MEM
29 * 0xc0000000-0xc0ffffff - PCI 0 I/O
30 * 0xc1000000-0xc1ffffff - PCI 1 I/O
