new-bus: Remove the 'rid' and 'type' arguments from BUS_*ACTIVATE_RESOURCE The public bus_activate/deactivate_resource() API still accepts both forms, but the internal kobj methods no longer pass the arguments. Implementations which need the rid or type now use rman_get_rid() or rman_get_type() to fetch the value from the allocated resource.

riscv: nexus code tidy-up Make a pass at the various nexus implementations, fixing some very minor style issues, obsolete comments, etc. The method declaration section has become unwieldy in many respects. Attempt to tame it by: - Using generated method typedefs - Grouping methods roughly by category, and then alphabetically. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D38495

ofwbus: remove arm64 ifdefs Rather than using the DEVICE_IDENTIFY method, let's have other ofwbus-using platforms add ofwbus0 explicitly in nexus, like arm64. This gives them the same flexibility, e.g. if riscv starts supporting ACPI, and cleans up the #ifdefs. We were doing this already on riscv, but adjust the 'order' parameters.

ofwbus: remove handling of resources from ofwbus The architecture nexus should handle allocation and release of memory and interrupts. This is to ensure that system-wide resources such as these are available to all devices, not just children of ofwbus0. On powerpc this moves the ownership of these resources up one level, from ofwbus0 to nexus0. Other architectures already have the required logic in their nexus implementation, so this eliminates the duplication of resources. An implementation of nexus_adjust_resource() is added for arm, arm64, and riscv. As noted by ian@ in the review, resource handling was the main bit of logic distinguishing ofwbus from simplebus. With some attention to detail, it should be possible to merge the two in the future. Co-authored by: mhorne MFC after: 1 month Differential Revision: https://reviews.freebsd.org/D30554

Support for v1.10 (latest) of RISC-V privilege specification. New version is not compatible on supervisor mode with v1.9.1 (previous version). Highlights: o BBL (Berkeley Boot Loader) provides no initial page tables anymore allowing us to choose VM, to build page tables manually and enable MMU in S-mode. o SBI interface changed. o GENERIC kernel. FDT is now chosen standard for RISC-V hardware description. DTB is now provided by Spike (golden model simulator). This allows us to introduce GENERIC kernel. However, description for console and timer devices is not provided in DTB, so move these devices temporary to nexus bus. o Supervisor can't access userspace by default. Solution is to set SUM (permit Supervisor User Memory access) bit in sstatus register. o Compressed extension is now turned on by default. o External GCC 7.1 compiler used. o _gp renamed to __global_pointer$ o Compiler -march= string is now in use allowing us to choose required extensions (compressed, FPU, atomic, etc).
