+DRIVERS

+Timer Driver, Console Driver, Opencores Ethernet Driver
+
+Notes
+=====
+
+This BSP supports single LEON3-processor system with minimum peripheral
+configuration of one UART. BSP reads system configuration area to get
+information such as memory mapping and usage of interrupt resources and
+installs device drivers based on this information.
+
+There are no restrictions on memory mapping of UARTS. Console driver
+operates in polled mode.
+
+Console driver uses timer 0 of General Purpose Timer and must be configured
+to use separate interrupts for each timer. No restrictions on memory mapping.
+Interrupt request signal can not be shared with other devices.
+
+Ethernet MAC core can be mapped in arbitrary memory address space and use
+arbitrary interrupt request signal. Interrupt request signal can not be
+shared with other devices.
