[PATCH v1 0/8] bootcount: introduce GPT-backed bootcount device

[dmukhin at ford.com]

This series adds new GPT-backed bootcount device with
ChromiumOS-inspired counters/flags logic [1].

Patch 1 is ChromiumOS-style 16-bit flags manipulation routines

Patch 2-5 introduce extension to existing 'gpt' command allowing
          the user to update top 16 bits of selected GPT PTE flags
          manually.

Patch 6 introduces the new bootcount device with compatible
        "u-boot,bootcount-gpt"

Patch 7 allow U-Boot running as a coreboot payload, to use new
        bootcount-gpt device.

Patch 8 excludes bootcount-gpt from being used in autoboot code path
        to allow custom bootflow logic.
