  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
