1728aef23d bhnd(4): Implement NVRAM support required for PMU bring-up.
- 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.

6ed73911fe [mips/broadcom] Fetch UART console configuration from CFE.
Relying on the boot loader console configuration allows us to use a
common set of device hints for all SENTRY5 devices.

ff29b85a34 Replace mips/sentry5 with mips/broadcom
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

7ba7852fd7 Switch mips/sentry5 to bhnd(4), and unify with mips/broadcom
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.

2db4962425 FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64,
mips32r2 and mips64r2 (and close relatives) processors.  There
presently is support for ADMtek ADM5120, A mips 4Kc in a malta board,
the RB533 routerboard (based on IDT RC32434) and some preliminary
support for sibtye/broadcom designs.  Other hardware support will be
forthcomcing.

This port boots multiuser under gxemul emulating the malta board and
also bootstraps on the hardware whose support is forthcoming...

Oleksandr Tymoshenko, Wojciech Koszek, Warner Losh, Olivier Houchard,
Randall Stewert and others that have contributed to the mips2 and/or
mips2-jnpr perforce branches.  Juniper contirbuted a generic mips port
late in the life cycle of the misp2 branch.  Warner Losh merged the
mips2 and Juniper code bases, and others list above have worked for
the past several months to get to multiuser.

In addition, the mips2 work owe a debt to the trail blazing efforts of
the original mips branch in perforce done by Juli Mallett.
