evbppc: Add support for DHT Walnut 405GP evaluation board.
(Digital Home Technologies PCB 01070201 Rev. 1.1)
Official web page seems gone, but analyses by Linux people are at:
- https://elinux.org/DHT-Walnut
- http://web.archive.org/web/20070225171826/http://supernova.stanford.edu/dingdong/
The board features:
- 266MHz PowerPC 405GP processor
- one PC133 SDRAM slot
- two 32-bit 5V PCI slot
- on-chip ethernet controller with DP83843 PHY
- on-chip serial port / GPIO controller
- on-board PDC20265 IDE controller
Hardware limitations:
- no MAC address assigned
- no RTC present
Known problem:
- atabus(4) channels cannot be attached to pdcide(4) for cold boot
dmesg:
- https://dmesgd.nycbug.org/index.cgi?do=view&id=5997
Have fun!
