- Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source files after they were repo-copied to sys/dev/atkbdc. The sources of atkbdc(4) and its children were moved to the new location in preparation for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in order to not further scatter them over the whole tree which would have been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another reason for the repo-copies was that some of the sources were misfiled, e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly. Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't ISA-specific. - Separate the parts of atkbdc_isa.c which aren't actually ISA-specific but are shareable between different atkbdc(4) bus front-ends into atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource() respectively in atkbdc_isa.c instead of rolling own versions. - Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for atkbdc(4). PS/2 controllers and input devices are used on a couple of Sun OEM boards and occur on either the EBus or the ISA bus. Depending on the board it's either the only on-board mean to connect a keyboard and mouse or an alternative to either RS232 or USB devices. - Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled without isa(4) (e.g. for EBus-only machines). This ISA-specific part isn't separated into its own source file, yet, as it requires more work than was feasible for 6.0 in order to do it in a clean way. Actually philip@ is working on a rewrite of psm(4) so a more comprehensive clean-up and separation of hardware dependent and independent parts is expected to happen after 6.0.
