* TOP860 is a simple module:
* 16-bit wide FLASH on CS0 (2MB or more)
* 32-bit wide DRAM on CS2 (either 4MB or 16MB)
* FEC with Am79C874 100-Base-T and Fiber Optic
* Ports available, but we choose SMC1 for Console
* 8k I2C EEPROM at address 0xae, 6k user available, 2k factory set
* 32768Hz crystal PLL set for 49.152MHz Core and 24.576MHz Bus Clock
