U-Boot for Hidden Dragon board
|
||
|
|
------------------------------
|
||
|
|
|
||
|
|
Hidden Dragon is a MPC824x-based board by Motorola. For the most
|
||
|
|
part it is similar to Sandpoint8245 board. So unless otherwise
|
||
|
|
mentioned, the codes in this directory are adapted from ../sandpoint
|
||
|
|
directory.
|
||
|
|
|
||
|
|
Apparently there are very few of this board out there. Even Motorola
|
||
|
|
website does not have any info on it.
|
||
|
|
|
||
|
|
RAM:
|
||
|
|
start = 0x0000 0000
|
||
|
|
size = 0x0200 0000 (32 MB)
|
||
|
|
|
||
|
|
Flash:
|
||
|
|
BANK ONE:
|
||
|
|
start = 0xFFE0 0000
|
||
|
|
size = 0x0020 0000 (2 MB)
|
||
|
|
flash chip = 29LV160TE (1x16 Mbits or 2x8 Mbits)
|
||
|
|
flash sectors = 16K, 2x8K, 32K, 31x64K
|
||
|
|
|
||
|
|
BANK TWO:
|
||
|
|
NONE
|
||
|
|
|
||
|
|
The processor interrupt vectors reside on the first 256 bytes
|
||
|
|
starting from address 0xFFF00000. The "reset vector" (first
|
||
|
|
instruction executed after reset) is located on 0xFFF0 0100.
|
||
|
|
|
||
|
|
U-Boot is configured to reside in flash starting at the address of
|
||
|
|
0xFFF00000. The environment space is located in flash separately from
|
||
|
|
U-Boot, at the second sector of the first flash bank, starting from
|
||
|
|
0xFFE04000 until 0xFFE06000 (8KB).
|
||
|
|
|
||
|
|
Network:
|
||
|
|
- RTL8139 chip on the base board (SUPPORTED)
|
||
|
|
- RTL8129 chip on the processor board (NOT SUPPORTED)
|
||
|
|
|
||
|
|
Serial:
|
||
|
|
- Two NS16550 compatible UART on the processor board (SUPPORTED)
|
||
|
|
- One NS16550 compatible UART on the base board (UNTESTED)
|
||
|
|
|
||
|
|
Misc:
|
||
|
|
VIA686A PCI SuperIO peripheral controller
|
||
|
|
- 2 USB ports (UNTESTED)
|
||
|
|
- 2 PS2 ports (UNTESTED)
|
||
|
|
- Parallel port (UNTESTED)
|
||
|
|
- IDE & floppy interface (UNTESTED)
|
||
|
|
|
||
|
|
S3 Savage4 video card (UNTESTED)

TODO:
|
||
|
|
-----
|
||
|
|
- Support for the VIA686A based peripherals
|
||
|
|
- The RTL8139 driver frequently gives rx error.
|
||
|
|
- Support for RTL8129 network controller. (Why is the support removed from
|
||
|
|
rtl8139.c driver?)
