8148f4f3d5 Enable usb low and full speed devices connected to the imx6 root hubs.
This enables the PHY circuitry for UTMI+ level 2 and 3, and sets the
flag to tell the ehci code that the root hub has a transaction translator
in it.  For imx6 we can use the standard ehci_get_port_speed_portsc()
function to find out what speed device is connected to the port.

93a065e749 Remake support for SMP kernel on UP cpu:
- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
   By this, any SMP kernel can be compiled with SMP_ON_UP support.
 - Enable runtime detection of CPU multiprocessor extensions only
   if SMP_ON_UP option is used. In other cases (pure SMP or UP),
   statically compile only required variant.
 - Don't leak multiprocessor instructions to UP kernel.
 - Correctly handle data cache write back to point of unification.
   DCCMVAU is supported on all armv7 cpus.
 - For SMP_ON_UP kernels, detect proper TTB flags on runtime.

Replace archaic "busses" with modern form "buses."

Intentionally excluded:

  * Old hardware in general
* Use of "busses" in code as identifiers

4d7f3703e2 Postpone allocation of IRQ resource to the time when interrupt
controller devices are attached. This has already been done for
bus_setup_intr().

There was no doubt that if someone wants to setup an interrupt,
corresponding interrupt controller device must already be attached.
However, the same must be valid for allocation of an interrupt resource
unless the allocation is done blindly, without any information that
such interrupt even exists. While it was done this blind way before,
it won't be possible after next INTRNG change.

183d468536 Another round of changes to add compatibility with the older ESHDC variety
of hardware.  Mostly this focuses on the big changes needed for setting the
bus clock, because ESDHC is SDHCI v2.0 and USDHC is 3.0, and the number,
location, and interpretation of clock divisor bits is vastly different
between the two.  This doesn't get the device all the way to functioning
on ESDHC hardware yet, but it's much closer, now getting through all the
card detection and negotiation of capabilties and speed (but it eventually
hangs on what appears to be a missing interrupt).

Another missing chunk of code for handling ESDHC's 32 bit command-and-mode
register using sdhci's pair of 16 bit writes is added.

This also does some leading whitespace cleanups and sorts some softc
struct members by size, and adds some comments (because when do I ever
touch code without adding comments?).

cd642c88a1 INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

bff6be3e9b Remove FDT specific parts from INTRNG. Change its interface to make it
universal.

(1) New struct intr_map_data is defined as a container for arbitrary
description of an interrupt used by a device. Typically, an interrupt
number and configuration relevant to an interrupt controller is encoded
in such description. However, any additional information may be encoded
too like a set of cpus on which an interrupt should be enabled or vendor
specific data needed for setup of an interrupt in controller. The struct
intr_map_data itself is meant to be opaque for INTRNG.

(2) An intr_map_irq() function is created which takes an interrupt
controller identification and struct intr_map_data as arguments and
returns global interrupt number which identifies an interrupt.

(3) A set of functions to be used by bus drivers is created as well as
a corresponding set of methods for interrupt controller drivers. These
sets take both struct resource and struct intr_map_data as one of the
arguments. There is a goal to keep struct intr_map_data in struct
resource, however, this way a final solution is not limited to that.

(4) Other small changes are done to reflect new situation.

This is only first step aiming to create stable interface for interrupt
controller drivers. Thus, some temporary solution is taken. Interrupt
descriptions for devices are stored in INTRNG and two specific mapping
function are created to be temporary used by bus drivers. That's why
the struct intr_map_data is not opaque for INTRNG now. This temporary
solution will be replaced by final one in next step.

dec4873723 Fix fallout from r292180 (Dec 2015)... ensure that every driver which has
a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc.  This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).
