Add the imx sdhci controller.

Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.

Add the missing ')' at end of sentence. Reword it to use a more common idiom.

Pass the kernel physical address to initarm through the boot param struct.

Make functions only used in vfp.c static, and remove vfp_enable.

Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to
place 32-bit data in r1, not r0. 64-bit data is already packed correctly.

Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us
remove the need to load the kernel at a fixed address.

Remove references to PHYSADDR where it's used only in debugging output.

Dynamically generate the page table. This will allow us to detect the
physical address we are loaded at to change the mapping.

Do not assume a value for #address-cells when parsing the OF translations
map. This allows the kernel to get farther with OpenBIOS on 64-bit CPUs.

Actually look up #address-cells instead of assuming it is correlated with
the Uninorth version number.

#interrupt-cells belongs to the iparent, not the device parent.

Add a sysctl to allow disabling resetting the OF syscons.

For PCI<->PCI bridges, #address-cells may be 3.

Make RTAS calls, which call setfault() to recover from machine checks,
preserve any existing fault buffer.

badaddr() is used only in the grackle PCI driver, so move its definition
there. Clean up a spurious setfault() declaration as well.

This [phyp_console] driver doesn't need the /options node, so don't check
for it.

Use the Open Firmware-based CPU frequency determination as a generic
fallback if we can't measure CPU frequency. This is also useful on a
variety of embedded systems using FDT.

Miffed r230993 due to a one-character typo while reviewing the patch.

Unify OF PCI infrastructure, including changing from parsing the device
tree based on heuristics to parsing it based on the spec. This should also
lay the foundation for NEW_PCIB on PowerPC.

- 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.

Rename INTR_VEC to MAP_IRQ. From the OFW or FDT we obtain a

Provide for multiple, cascaded PICs on PowerPC systems, and extend the
OFW interrupt map interface to also return the device's interrupt parent.

MFC after: 8.1-RELEASE

Fix the OFW interrupt map parser to use its own idea of the number of interrupt
cells in the map, instead of using a value passed to it and then panicing if it
disagrees. This fixes interrupt map parsing for PCI bridges on some Apple
Uninorth PCI controllers.

Adapt parts of the sparc64 Open Firmware bus enumeration code (in particular,
the code for parsing interrupt maps) to PowerPC and reflect their new MI
status by moving them to the shared dev/ofw directory.

This commit also modifies the OFW PCI enumeration procedure on PowerPC to
allow the bus to find non-firmware-enumerated devices that Apple likes to add,
and adds some useful Open Firmware properties (compat and name) to the pnpinfo
string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the
change to PCI enumeration on PowerPC, X has started working again on PPC
machines with Grackle hostbridges.

Convert PowerPC AIM PCI and nexus busses to standard OFW bus interface. This
simplifies certain device attachments (Kauai ATA, for instance), and makes
possible others on new hardware.

On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.

MFamd64/ia64/i386: Only set the rman bus tags and handles in
bus_activate_resource() methods instead of splitting it up between
bus_alloc_resource() and bus_activate_resource().

Glanced at by: marcel

Redefine bus_space_tag_t on PowerPC from a 32-bit integral to
a pointer to struct bus_space. The structure contains function
pointers that do the actual bus space access.

The reason for this change is that previously all bus space
accesses were little endian (i.e. had an explicit byte-swap
for multi-byte accesses), because all busses on Macs are little
endian.
The upcoming support for Book E, and in particular the E500
core, requires support for big-endian busses because all
embedded peripherals are in the native byte-order.

With this change, there's no distinction between I/O port
space and memory mapped I/O. PowerPC doesn't have I/O port
space. Busses assign tags based on the byte-order only.
For that purpose, two global structures exist (bs_be_tag and
bs_le_tag), of which the address can be taken to get a valid
tag.

Make the PCI code aware of PCI domains (aka PCI segments) so we can
support machines having multiple independently numbered PCI domains
and don't support reenumeration without ambiguity amongst the
devices as seen by the OS and represented by PCI location strings.
This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
by pciconf(8) has been changed and that consumers of <sys/pciio.h>
potentially need to be recompiled.
