+BSP NAME: sis
+BOARD: any based on the European Space Agency's ERC32
+BUS: N/A
+CPU FAMILY: sparc
+CPU: ERC32 (SPARC V7 + on-CPU peripherals)
+ based on Cypress 601/602
+COPROCESSORS: on-chip 602 compatible FPU
+MODE: 32 bit mode
+
+DEBUG MONITOR: none
+
+PERIPHERALS
+===========
+TIMERS:
+ NAME: General Purpose Timer
+ RESOLUTION: 50 nanoseconds - 12.8 microseconds
+ NAME: Real Time Clock Timer
+ RESOLUTION: 50 nanoseconds - 3.2768 milliseconds
+ NAME: Watchdog Timer
+ RESOLUTION: XXX
+SERIAL PORTS: 2 using on-chip UART
+REAL-TIME CLOCK: none
+DMA: on-chip
+VIDEO: none
+SCSI: none
+NETWORKING: none
+
+DRIVER INFORMATION
+==================
+CLOCK DRIVER: ERC32 internal Real Time Clock Timer
+IOSUPP DRIVER: N/A
+SHMSUPP: N/A
+TIMER DRIVER: ERC32 internal General Purpose Timer
+CONSOLE DRIVER: ERC32 internal UART
+
+STDIO
+=====
+PORT: Channel A
+ELECTRICAL: na since using simulator
+BAUD: na
+BITS PER CHARACTER: na
+PARITY: na
+STOP BITS: na
+
+Notes
+=====
+
+ERC32 BSP only supports single processor operations.
+
+A nice feature of this BSP is that the RAM and PROM size are set in the
+linkcmds file and the startup code programs the Memory Configuration
+Register based on those sizes.
+
+The Watchdog Timer is disabled.
+
+This code was developed and tested entirely using the SPARC Instruction
+Simulator (SIS) for the ERC32. All tests were known to run correctly
+against sis v1.7.
+
+
+Memory Map
+==========
+
+0x00000000 - 0x00000000 + _PROM_SIZE code and initialized data
+0x01f80000 on chip peripherals
+0x00000000 - 0x02000000 + _RAM_SIZE destination for initialized data
+ BSS (i.e. unitialized data)
+ C Heap (i.e. malloc area)
+ RTEMS Workspace
+
+The C heap is assigned all memory between the end of the BSS and the
+RTEMS Workspace. The size of the RTEMS Workspace is based on that
+specified in the application's configuration table.
