[PATCH 00/22] i.MX BBU improvements and bugfixes

[Andrey Smirnov <andrew.smirnov@gmail.com>]

Everyone:

This series is the result simplification, bugfixing and adding
features to some of the code in BBU subsytem:

  - Patch 2 "filetype: Add code to detect i.MX image v1" is not really
    used anywhere in the series and is provided for the sake of
    completness. It should probably dropeed but I thought I'd include
    it just in case

  - Patches 1, 3 - 12 are a number of code simplifications intended to
    minimize amount of duplicated code as well as generic improvements
    (IMHO)

  - Patches 13 - 17 are i.MX8MQ and VF610 related changes

  - Patches 18 - 22 are a result of discovering that a number of error
    cases were silently ignored and not reported as update
    failures. Patch 20 is technically not related to BBU at all, but
    since I discovered the problem while working on this series, I
    kept it as a part of this series

This patchset was tested of following platforms:

  - i.MX51 ZII RDU1 (SPI-NOR and eMMC)
  - i.MX6Q ZII RDU2 (SPI-NOR and eMMC)
  - VF610 ZII Vybrid Dev Board Rev C. (SPI-NOR)
  - i.MX8MQ NXP EVK (eMMC)
  - i.MX8MQ ZII RDU3 (not supported by upstream Barebox)

Feedback is wellcome!

Thanks,
Andrey Smirnov
