Some of the existing code is flipping between __raw_xxx() and
pci_{read,write}_reg(). As the latter are just wrappers for the former,
flip over to using them consistently.

Presently we error out if a link is disabled and simply drop the port
registration outright. This follows the PPC changes and simply reports on
the link state on boot, leaving the port registered, in order to more
easily deal with hotplug on future parts.

The SH7786 PCIe is presently unable to enumerate itself in root complex
mode, and has no visibility through either type 0 or type 1 accesses,
despite having a mostly sensible extended config space for each port.
Attempts to generate type 0 or type 1 config cycles result in completer
aborts, so we're ultimately forced to use SuperHyway transactions
instead.

As each port has a single port <-> device mapping that resolves for any
PCI_SLOT definition, we simply hijack devfn 0 for the SuperHyway
transaction and bump up the devfn limit.

With enumeration of the root complex now possible, we also need to insert
an early fixup to hide the BARs from the kernel. With all of that done,
it's now possible to use the pcieport services with all of the PCIe
ports, which is the first step to power management support.

Previously these IDs were only used by one driver, so there was not much
need for having them generically defined. Now that this will no longer
hold true, move them over.

The spec suggests waiting up to 500ms for the PHY to settle before
testing link state, but practice shows that 100ms is sufficient (this is
the delay value we also use on the other SH-4A PCI controllers, too).
This makes device detection much more reliable, although in the future it
should be a bit faster to simply serialize with a TLP IRQ.

The _remove() routine is flagged __init_or_module, despite only being

balanced out with __devinit, switch to __devexit and __devexit_p()
wrapping.

The current probe/remove definitions are split between __init and

Now that the rest of the socket calls are provided through their own
paths, do the same for sys_recvmmsg. It's unlikely we'll ever be able to
kill off the socketcall path, but this at least permits userspace to
gradually begin migrating.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Linux kernel already has socket syscalls that can be invoked
without the multiplexing sys_socketcall wrapper.
C library wrappers are ready to use them directly. It needs just
to define the missing syscall numbers and provide the related entries
into the syscalls table, like sh64 aleady does.

As the help for the config option suggests, this option really shouldn't

Now that the resource assignment issues are resolved, we can finally wire
up the small third memory window -- in the future we may reclaim this for
MSI.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

An IORESOURCE_IO was missing here, which meant that we weren't properly
establishing the I/O window for this particular slot. With this
corrected, cards with I/O BARs have them actually assigned and
accessible.

Certain memory windows are only available for 32-bit space, so skip over
these in 29-bit mode. This will severely restrict the amount of memory
that can be mapped, but since a boot loader bug makes booting in 29-bit
mode close to impossible anyways, everything is ok.

This bumps up the low address to match the physical memory windows for

This was killed off by a simplification patch previously that failed to
take the cpufreq use case in to account, so reinstate the old bounding
logic. The lowest rate bounding on the other hand was broken in that it
never actually got assigned a rate and the best fit rate was instead just
getting lucky based on the ordering of the rate table, fix this up so the
code actually does what it was intended to do originally.
