Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?). |

$NetBSD: README,v 1.3 2005/12/11 12:17:04 christos Exp $ This is a port of NetBSD to the FIC8234 VME processor board, made by the swiss company CES (Geneve). These boards are (or have been) popular in high energy physics data acquisition (think of CERN!). See http://www.ces.ch/Products/CPUs/FIC8234/FIC8234.html for some technical data. The highlights: - MC68040 processor at 25 MHz (optional dual-processor) - 8 or 32 MByte RAM - 2 serial ports on Z85c30 - 79c900 (ILACC) ethernet - 53c710 SCSI The port is quite rudimentary at the moment. The kernel is started out of a running OS-9 system. SCSI support is not present yet, so it only works diskless with NFS (or ramdisk - not tested) root. It is good enough for multiuser, self-hosting etc. however. To start it: - make OS image by "objcopy --output-target=binary netbsd <imagename>" - load image to physical address 0x20100000 (RAM start + 1M) - jump to 0x20100400 For questions and contributions, contact Matthias Drochner (drochner@NetBSD.org).
