Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

sys: use our roundup2/rounddown2() macros when param.h is available.
rounddown2 tends to produce longer lines than the original code and when the code has a high indentation level it was not really advantageous to do the replacement.
This tries to strike a balance between readability using the macros and flexibility of having the expressions, so not everything is converted.

As <machine/pmap.h> is included from <vm/pmap.h>, there is no need to include it explicitly when <vm/pmap.h> is already included.

Convert rman to use rman_res_t instead of u_long
Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of u_long.
Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

Add domain support to PCI bus allocation
When the system has more than a single PCI domain, the bus numbers are not unique, thus they cannot be used for "pci" device numbering. Change bus numbers to -1 (i.e. to-be-determined automatically) wherever the code did not care about domains.

Don't disable PCIe just because the host is not a PCI host; the latter flag only applies to non-PCIe systems. If PCIe is in target mode, it will simply and gracefully fail to attach of its own accord.

Don't attach if the bootloader has not indicated that we're a PCI host. This fixes booting on systems which are PCI targets.

Merge the Cavium Octeon SDK 2.3.0 Simple Executive code and update FreeBSD to make use of it where possible.
This primarily brings in support for newer hardware, and FreeBSD is not yet able to support the abundance of IRQs on new hardware and many features in the Ethernet driver.
Because of the changes to IRQs in the Simple Executive, we have to maintain our own list of Octeon IRQs now, which probably can be pared-down and be specific to the CIU interrupt unit soon, and when other interrupt mechanisms are added they can maintain their own definitions.
Remove unmasking of interrupts from within the UART device now that the function used is no longer present in the Simple Executive. The unmasking seems to have been gratuitous as this is more properly handled by the buses above the UART device, and seems to work on that basis.

- There's no need to overwrite the default device method with the default one. Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily. Discussed with: jhb, marcel - While at it, use DEVMETHOD_END. Discussed with: jhb - Also while at it, use __FBSDID.

Don't attach the PCI bus driver if the board we're being run on has PCIe. The two are mutually-exclusive on Octeon.

Give devices lots of time to settle around programming BARs and command registers. Without this, the settings do not seem to stick for Atheros NICs in the PCI slot of the Lanner MR-320.

o) Program the Lanner MR-320 for 32-bit mode, too. o) Give a virtual address for I/O ports on n64. o) On the Portwell CAM-0100, return the right IRQ for the on-board SATA. o) Except on bridges, only set PORTEN and MEMEN on devices that have I/O or memory BARs respectively. o) Disable PORTEN and MEMEN while reprogramming BARs. o) On the Lanner MR-955, set the Tx DMA power register for the on-board Promise SATA controller.

o) Add bus_teardown_intr for pci and ciu. This allows the Promise SATA driver to try to switch interrupt handlers at setup. It's not a very good implementation of bus_teardown_intr, though. o) Set cache line size and latency timers for PCI devices per Linux.

Flesh out PCI bus support some: o) Reset and configure the bus from scratch rather than expecting U-Boot to do it for us. Values and configuration from Linux, U-Boot and comments in the Cavium Simple Executive sources. o) Do a resource assignment and bus numbering pass in the absence of a PCI BIOS or firmware that will do it for us. XXX This has to be the third or fourth instance of this in FreeBSD and it would be nice to have it become part of the PCI bus driver itself, like it is on Linux. o) Fix interrupt mapping for and adjust bus configuration for the Lanner MR-955, based on information provided by Lanner.

Update the port of FreeBSD to Cavium Octeon to use the Cavium Simple Executive library: o) Increase inline unit / large function growth limits for MIPS to accommodate the needs of the Simple Executive, which uses a shocking amount of inlining. o) Remove TARGET_OCTEON and use CPU_CNMIPS to do things required by cnMIPS and the Octeon SoC. o) Add OCTEON_VENDOR_LANNER to use Lanner's allocation of vendor-specific board numbers, specifically to support the MR320. o) Add OCTEON_BOARD_CAPK_0100ND to hard-wire configuration for the CAPK-0100nd, which improperly uses an evaluation board's board number and breaks board detection at runtime. This board is sold by Portwell as the CAM-0100. o) Add support for the RTC available on some Octeon boards. o) Add support for the Octeon PCI bus. Note that rman_[sg]et_virtual for IO ports can not work unless building for n64. o) Clean up the CompactFlash driver to use Simple Executive macros and structures where possible (it would be advisable to use the Simple Executive API to set the PIO mode, too, but that is not done presently.) Also use structures from FreeBSD's ATA layer rather than structures copied from Linux. o) Print available Octeon SoC features on boot. o) Add support for the Octeon timecounter. o) Use the Simple Executive's routines rather than local copies for doing reads and writes to 64-bit addresses and use its macros for various device addresses rather than using local copies. o) Rename octeon_board_real to octeon_is_simulation to reduce differences with Cavium-provided code originally written for Linux. Also make it use the same simplified test that the Simple Executive and Linux both use rather than our complex one. o) Add support for the Octeon CIU, which is the main interrupt unit, as a bus to use normal interrupt allocation and setup routines. o) Use the Simple Executive's bootmem facility to allocate physical memory for the kernel, rather than assuming we know which addresses we can steal. NB: This may reduce the amount of RAM the kernel reports you as having if you are leaving large temporary allocations made by U-Boot allocated when starting FreeBSD. o) Add a port of the Cavium-provided Ethernet driver for Linux. This changes Ethernet interface naming from rgmxN to octeN. The new driver has vast improvements over the old one, both in performance and functionality, but does still have some features which have not been ported entirely and there may be unimplemented code that can be hit in everyday use. I will make every effort to correct those as they are reported. o) Support loading the kernel on non-contiguous cores. o) Add very conservative support for harvesting randomness from the Octeon random number device. o) Turn SMP on by default. o) Clean up the style of the Octeon kernel configurations a little and make them compile with -march=octeon. o) Add support for the Lanner MR320 and the CAPK-0100nd to the Simple Executive. o) Modify the Simple Executive to build on FreeBSD and to build without executive-config.h or cvmx-config.h. In the future we may want to revert part of these changes and supply executive-config.h and cvmx-config.h and access to the options contained in those files via kernel configuration files. o) Modify the Simple Executive USB routines to support getting and setting of the USB PID.
