[U-Boot] [PATCH v3 0/5] Update for inka4x0 plus some new features

[Detlev Zundel]

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 v2:

Addresses comments from ML.  Specifically:
- Fixing the odd empty line here and there
- Removed some cruft uncovered in the review process
- Rebased against master becaus some patches were
  already applied by Wolfgang.

Detlev Zundel (5):
  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.
