# # LEON3 BSP README # # $Id$ # # # BSP NAME: leon3 BUS: AMBA Plug & Play CPU FAMILY: sparc CPU: LEON3 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.
