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.
