sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

First of several commits as this driver is dusted off and maybe brought up to date. Principle changes for this reelase is to support 2K Port Login firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only come with the 2K Port Login firmware. The 2322 should now work- but we don't have firmware sets for it in ispfw (as the change to load 2K Port Login f/w hasn't been made- that f/w is so big it has to be loaded in more than one chunk). Other changes are the beginnings of cleaning up some long standing target mode issues. The next changes here will incorporate a lot of bug fixes from others. Finally, some copyright cleanup and attempts to make the parts of the driver that are FreeBSD specific start conforming more to FreeBSD style. MFC after: 1 month

'Support' for ISP SBus cards. This code does not imply that SBus cards work yet. They hang for me. But I can't netboot the latest snapshot on my ultra1e, and things hang at bus_setup_intr time. Since I'm offline for a while, I thought I'd toss this in in case somebody else who has a bit better luck wants to fart around with it. Please try and wait until I get back to check things in.

Some rearrangement of headers to minimize diffs with outside of FreeBSD repository and to clean up the license header so as to not pollute the license with file function. Zero all mailbox structures prior to use (just in case). Change the outgoing mailbox count for INIT_FIRMWARE to be correct.

Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months

- Introduce an ofw_bus kobj-interface for retrieving the OFW node and a subset ("compatible", "device_type", "model" and "name") of the standard properties in drivers for devices on Open Firmware supported busses. The standard properties "reg", "interrupts" und "address" are not covered by this interface because they are only of interest in the respective bridge code. There's a remaining standard property "status" which is unclear how to support properly but which also isn't used in FreeBSD at present. This ofw_bus kobj-interface allows to replace the various (ebus_get_node(), ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type() vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one. This in turn allows to simplify and remove code-duplication in drivers for devices that can hang off of more than one OFW supported bus. - Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the drivers for their children to use the ofw_bus kobj-interface. The IVAR- interfaces of the Central, EBus and FHC are entirely replaced by this. The PCI bus driver used its own kobj-interface and now also uses the ofw_bus one. The IVARs special to the SBus, e.g. for retrieving the burst size, remain. Beware: this causes an ABI-breakage for modules of drivers which used the IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be recompiled. The style-inconsistencies introduced in some of the bus drivers will be fixed by tmm@ in a generic clean-up of the respective drivers later (he requested to add the changes in the "new" style). - Convert the powerpc MacIO bus driver and the drivers for its children to use the ofw_bus kobj-interface. This invloves removing the IVARs related to the "reg" property which were unused and a leftover from the NetBSD origini of the code. There's no ABI-breakage caused by this because none of these driver are currently built as modules. There are other powerpc bus drivers which can be converted to the ofw_bus kobj-interface, e.g. the PCI bus driver, which should be done together with converting powerpc to use the OFW PCI code from sparc64. - Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take advantage of the ofw_bus kobj-interface and simplify them a bit.

This invloves removing the IVARs related to the "reg" property which were unused and a leftover from the NetBSD origini of the code. There's no ABI-breakage caused by this because none of these driver are currently built as modules. There are other powerpc bus drivers which can be converted to the ofw_bus kobj-interface, e.g. the PCI bus driver, which should be done together with converting powerpc to use the OFW PCI code from sparc64. - Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take advantage of the ofw_bus kobj-interface and simplify them a bit.

- Don't shift the clock frequency in MHz left by 8 before assigning it to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64 as sbus_mdvec.dv_clock is used to limit the clock rate of chips when a machine isn't able to support them at maximum speed which isn't the case for sun4u machines. - Remove the code that checks whether the clock frequency returned by sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's already done in sbus(4).

Convert isp(4) and ispfw(4) to use firmware(9) to manage firmware loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months

Make sure that if are in fact using 'full SMP', make the interrupt flags include INTR_MPSAFE. Put the flags in a common place so that both isp_sbus && isp_pci DTRT. In isp_mbxdma setup, drop any locks prior to calling things like bus_dmatag_create. This gets rid of these obnoxious WITNESS messages about 'sleeping with locks held' blah blah blah blah blah.

a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

Reform the busdma API so that new types may be added without modifying every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.
