- 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?)
