New bsp for the erc32/sis from Jiri Gaisler <jgais@wd.estec.esa.nl> which
runs on either the real hardware or the sparc instruction simulator. This bsp requires sis version 2.6 or later. This bsp supercedes the sis bsp.

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.
