28 * TOP860 is a simple module:
29 * 16-bit wide FLASH on CS0 (2MB or more)
30 * 32-bit wide DRAM on CS2 (either 4MB or 16MB)
31 * FEC with Am79C874 100-Base-T and Fiber Optic
32 * Ports available, but we choose SMC1 for Console
33 * 8k I2C EEPROM at address 0xae, 6k user available, 2k factory set
34 * 32768Hz crystal PLL set for 49.152MHz Core and 24.576MHz Bus Clock
36 * This config has been copied from MBX.h / MBX860T.h
39 * board/config.h - configuration options, board specific
46 * High Level Configuration Options
