Autoconfig notes

Autoconfig assigns:

  • Z2 fast RAM in 0x00200000-0x009FFFFF.
  • PiSCSI Z2 ROM/device window (typical 0x00E90000 base).
  • A314 device at 0x00EA0000.
  • PiStorm interaction device at 0x00EB0000.
  • Z3 fast RAM in high address space (e.g. 0x40000000+).

Keep Z2 strictly within 8 MB for compatibility. Use Z3 for larger buffers and DMA windows.
