-/*  LEON2 Hardcoded bus driver.
- *
- *  COPYRIGHT (c) 2008.
- *  Cobham Gaisler AB.
- *
- *  Bus driver for a hardcoded setup. LEON2 systems have some
- *  cores always present, here called "Standard Cores". In 
- *  addtion to the standard cores there are often extra cores
- *  that can be defined using the "Custom Cores" mechanism.
- *
- *  A Core is described by assigning a base register and 
- *  IRQ0..IRQ15 using the leon2_core structure.
