- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Identify Netlogic XLP 8xx B1 chip revisions

Add functions to check for 8xx B0 and 3xx Ax revisions which will
be used in network block initialization.

Update memory and resource allocation code for SoC devices

The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
he default bus space cannot be used for these.

Subclass pci and override attach and resource allocation methods to
take care of this.

Remove earlier code which did this partially.

Support for XLP4xx and XLP 8xx B0 revision

- Add 4xx processor IDs, add workaround in CPU detection code.
- Update frequency detection code for XLP 8xx.
- Add setting device frequency code.
- Update processor ID checking code.

Merge XLP 3XX updates and related rework.

* Update message station (CMS) code, read queue ids from PCI header.
* Use interrupts to wakeup message handling threads on 3XX
* Update PIC code, read interrupt information from PCI header instead
of using fixed values.
* Update PCI interrupt handling for the PIC change.
* Update code for getting chip frequency, new code support XLP 3XX
* Misc style(9) fixes

MIPS XLP platform code update.

* Update the hardware access register definitions and functions to bring
them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support
>32 cpus.

Add MIPS platform files for Netlogic XLP SoC.

Processor, UART, PIC and Messaging Network code. Also add
sys/mips/nlm/hal for on-chip device registers.
