eb175e8bfb [mips/broadcom]: Replace static frequency table with generic PMU clock
handling.


- Extended PWRCTL/PMU APIs to support querying clock frequency during very
  early boot, prior to bus attach.
- Implement generic PMU-based calculation of UART rclk values.
- Replaced use of static frequency tables (bcm_socinfo) with
  runtime-determined values.

cb4abe62ba [mips/broadcom] Generic platform_reset() support.
This adds support for performing platform_reset() on all supported
devices, using early boot enumeration of chipc capabilities and
available cores.


- Added Broadcom-specific MIPS CP0 register definitions used by
  BCM4785-specific reset handling.
- Added a bcm_platform structure for tracking chipc/pmu/cfe platform
  data.
- Extended the BCMA EROM API to support early boot lookup of core info
  (including port/region mappings).
- Extended platform_reset() to support PMU, PMU+AOB, and non-PMU
  devices.

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.

041b2de9cc [mips/broadcom] Add initial support for Broadcom MIPS processor
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.
