This patch adds driver implementation for BHND USB core. Driver has been
imported from ZRouter project with small adaptions for FreeBSD 11.
Also it's enabled for BroadCom MIPS74k boards by default. It's fully tested
on Asus boards (RT-N16: external USB, RT-N53: USB bus between SoC and WiFi
chips).

This adds support for EARLY_PRINTF via the CFE console; the aim is to
provide a fix for the otherwise cyclic dependency between PMU discovery
and console printf/DELAY:
- We need to parse the bhnd(4) core table to determine the address (and
type) of the PMU/PLL registers and calculate the CPU clock frequency.
- The core table parsing code will emit a printf() if a parse error is
hit.
- Safely calling printf() without EARLY_PRINTF requires a working
DELAY+cninit, which means we need the PMU.
Errors in core table parsing shouldn't happen, but lack of EARLY_PRINTF
makes debugging more difficult.

- Added a generic bhnd_nvram_parser API, with support for the TLV format
used on WGT634U devices, the standard BCM NVRAM format used on most
modern devices, and the "board text file" format used on some hardware
to supply external NVRAM data at runtime (e.g. via an EFI variable).
- Extended the bhnd_bus_if and bhnd_nvram_if interfaces to support both
string-based and primitive data type variable access, required for
common behavior across both SPROM and NVRAM data sources.
- Extended the existing SPROM implementation to support the new
string-based NVRAM APIs.
- Added an abstract bhnd_nvram driver, implementing the bhnd_nvram_if
atop the bhnd_nvram_parser API.
- Added a CFE-based bhnd_nvram driver to provide read-only access to
NVRAM data on MIPS SoCs, pending implementation of a flash-aware
bhnd_nvram driver.

The delta between SENTRY5 and BCM was already small due to BCM being
derived from SENTRY5; re-integrating the two avoids the maintenance
overhead of keeping them both in sync with bhnd(4) changes.
- Re-integrate minor SENTRY5 deltas in bcm_machdep.c
- Modify uart_cpu_chipc to allow specifying UART debug/console flags via
kenv and device hints.
- Switch SENTRY5 to std.broadcom
- Enabled CFI flash support for SENTRY5

Now that bhnd(4) provides feature parity with the previous siba/mips
implementation, we can switch sentry5 over and begin lifting common
support code out for use across bhnd(4) embedded targets.
Changes:
- Fixed enumeration of siba(4) per-core address maps, required for
discovery of memory mapped chipc flash region on siba(4) devices.
- Simplified bhnd kernel configuration (dropped 'bhndbus' option).
- Replaced files.broadcom's direct file references with their
corresponding standard kernel options.
- Lifted out common bcma/siba nexus support, inheriting from the new
generic bhnd_nexus driver.
- Dropped now-unused sentry5 siba code.
- Re-integrated BCM into the universe build now that it actually compiles.

Etherswitch support is built by default on all SoCs except RT3662/RT3883
as they have no built-in switch and their configurations with external

Relies on BHND(4) driver.
There files contains machine-dependent code for Broadcom MIPS processor and
provide UART driver.
This is a work in progress; it and the current bhnd code is enough to boot
on the ASUS RT-N16 and RT-N53 platforms.

legacy siba sentry5 cpu glue.
The siba_cc code is the hard-coded chipcommon bits for the sentry s5,
which will eventually be replaced with the more flexible bhnd sipa/cc
code.
bwn, etc uses siba_bwn, which doesn't use siba or siba_cc to do anything.
Only compile what each SoC needs and get rid of MEDIATEK generic config.

the following:
1. Give the appropriate board dts file to be used by either:
1.1. edit the SoC kernel config required (e.g., MT7620A_FDT) and include
the required FDT_DTS_FILE makeoption; or
1.2. simply supply FDT_DTS_FILE="xx.dts" on the command line when building
the kernel
Of course, the user can also create a completely new kernel config to
match the desired board and include the SoC kernel config from within
it.
If required, edit the MEDIATEK config file, which includes optional
drivers and comment out the unneeded ones.
2.1. this would only make sense if kernel size is a concern. Even if we
build the kernel with all drivers, if we lzma it and package it as a uImage,
its size is still around 1.1MiB.
The user will have to choose a dts file (or create a new one) from
sys/gnu/dts/mips , where all Mediatek/Ralink dts files will be imported via
a later revision.

This revision does the following renames:
CPU_MIPS24KC -> CPU_MIPS24K
CPU_MIPS74KC -> CPU_MIPS74K
CPU_MIPS1004KC -> CPU_MIPS1004K
It also adds the following new CPU_MIPSxxx options:
CPU_MIPS24KE, CPU_MIPS34K, CPU_MIPS1074K, CPU_INTERAPTIV, CPU_PROAPTIV
CPU_MIPSxxxxKC is limiting and possibly misleading as it implies the
MIPSxxxxK CPU has no FPU.
It would be better if the CPUs are named after their standard functionalities
only and the presence or absence of FPU can then be controlled via the
CPU_HAVEFPU option.
I will send out another dependent revision that moves MIPS 32 r2 and r3
CPUs to use the EHB instruction for clearing hazards instead of NOP/SSNOP.

This is an AR9331 part based on the AP121 reference design but with
32MB RAM. Yes, it has 4MB flash and it has no USB, so clever hacks
are required to get it up and working.
But boot/work it does.
The ERL is a fairly cheap (~$100 USD) and readily available dual core
MIPS64 device so it makes a useful MIPS reference platform.
This is based in part on the kernel config generated by the mkerlimage
script from http://rtfm.net/FreeBSD/ERL/.
