[U-Boot] [PATCH v2 0/7] Update for inka4x0 plus some new features

[Detlev Zundel <dzu@denx.de>]

This patchset contains updates for the ink4x0 platform.  Namely it
adds hardware diagnostic funtions and an RTC driver.

For a nice integration by using private command tables, do_help is
extended to support this scenario also.

To successfully convert all the pointer access to accessor macros, a
bunch of new defines is also needed for the 5200 cpu.


Changes from v1:

Addresses comments from ML.  Specifically:
- Moved ns16650 defines to proper include file.
- Used structures from this header file to access UARTs - this
  nicely eliminates serial_{in,out}.
- Convert inka_diag.c pointer accesses to accessor macros.
- Move variable declarations to start of functions.

A diff of the "before" and "after" branches will be posted seperately
for easier inspection.


Detlev Zundel (7):
  command.c: Expose the core of do_help as _do_help to the rest of
    u-boot.
  mpc5xxx: Add structure definition for several more register blocks.
  drivers/twserial: Add protocol driver for "three wire serial"
    interface.
  rtc: add support for 4543 RTC (manufactured by e.g. EPSON)
  inka4x0: Add hardware diagnosis functions for inka4x0
  inka4x0: Add hardware diagnosis and RTC in configuration.
  inka4x0: Use proper accessor macros for memory mapped registers.
