* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=326255

* Replace multiple nearly-identical copies of code to walk through an FDTIan Lepore2014-09-251-1/+0
| | | | | | | | | | | | | | | | | | | node's interrupts=<...> property creating resource list entries with a single common implementation. This change makes ofw_bus_intr_to_rl() the one true copy of that code and removes the copies of it from other places. This also adds handling of the interrupts-extended property, which allows specifying multiple interrupts for a node where each interrupt can have a separate interrupt-parent. The bindings for this state that the property cells contain an xref phandle to the interrupt parent followed by whatever interrupt info that parent normally expects. This leads to having a variable number of icells per interrupt in the property. For example you could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.

This probably has a short half-life (as do most of the fdt_ functions), but it helps solve some near-term needs until we work out the larger problems of device instantiation order versus the order of things in the fdt data.

* Retire machine/fdt.h as a header used by MI code, as its function is nowNathan Whitehorn2014-01-051-1/+0
| | | | | | | | | | | | | | | | | | obsolete. This involves the following pieces: - Remove it entirely on PowerPC, where it is not used by MD code either - Remove all references to machine/fdt.h in non-architecture-specific code (aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat non-arch-specific). - Fix code relying on header pollution from machine/fdt.h includes - Legacy fdtbus.c (still used on x86 FDT systems) now passes resource requests to its parent (nexus). This allows x86 FDT devices to allocate both memory and IO requests and removes the last notionally MI use of fdtbus_bs_tag. - On those architectures that retain a machine/fdt.h, unused bits like FDT_MAP_IRQ and FDT_INTR_MAX have been removed.
