1.1.3 Mips core Targets Supported

The Crt0 startup file should run on any mips target that doesn’t require additional hardware initialization. The I/O code so far only supports a custom LSI33k based RAID disk controller board. It should easy to change to support the IDT line of eval boards. Currently the two debugging protocols supported by GDB for mips targets is IDT’s mips debug protocol, and a customized hybrid of the standard GDB remote protocol and GDB’s standard ROM monitor support. Included here is the debug stub for the hybrid monitor. This supports the LSI33k processor, and only has support for the GDB protocol commands g, G, m, M, which basically only supports the register and memory reading and writing commands. This is part of libgloss and is called lsi33k-stub.c.

The crt0.S should also work on the IDT line of eval boards, but has only been run on the LSI33k for now. There is no I/O support for the IDT eval board at this time. The current I/O code is for a customized version of LSI’s pmon ROM monitor. This uses entry points into the monitor, and should easily port to other versions of the pmon monitor. Pmon is distributed in source by LSI.
