This simplifies the SPARC FS workload significantly, and removes assumptions about what ROMs exist, where they go, etc. It removes other components from the loop which don't have anything to contribute as far as setting up the ROMs. One side effect of this is that there isn't specialized support for adding PC based events which would fire in the ROMs, but that was never done and the files that were being used were flat binary blobs with no symbols in the first place. This also necessitates building a unified image which goes into the single 8MB ROM that is located at address 0xfff0000000. That is simply done with the following commands: dd if=/dev/zero of=t1000_rom.bin bs=1024 count=8192 dd if=reset_new.bin of=t1000_rom.bin dd if=q_new.bin of=t1000_rom.bin bs=1024 seek=64 dd if=openboot_new.bin of=t1000_rom.bin bs=1024 seek=512 This results in an 8MB blob which can be loaded verbatim into the ROM. Alternatively, and with some extra effort, an ELF file could be constructed which had each of these components as segments, offset to the right location in the ELF header. That would be slightly more work to set up, but wouldn't waste space on regions of the image that are all zeroes.
