Subject: [PATCH v3 0/1] platform/x86: Add Slim Bootloader firmware update support

v3 addresses review comment from Andy Shevchenko to v2.

Changes in v3
 - Renamed the driver file to intel-wmi-sbl-fw-update.c. This resulted in
   various changes like:
    - renaming, reordering the driver entry in Makefile and Kconfig
    - renaming, reordering the MAINTAINERS file entry
    - renamed the ABI file
    - renaming few data structures and wmi_driver entries to reflect the
      new name

v2 Upstream submission is available here:

>From v2 submission:

v1 Upstream submission is available here:
https://lore.kernel.org/lkml/20200420194405.8281-1-jithu.joseph@intel.com

v2 primarily addresses review comments from Andy Shevchenko to v1. 

Changes in v2
 - Rebased on top of tag: v5.7-rc2
 - Added ABI documentation file
 - Changed the ordering of SBL entry in Makefile and Kconfig
 - Replaced kstrtobool() with kstrtouint() for user input processing
 - Added DocLink: tag to annottate weblink in commit message
 - Minor edits to commit message in p1/1
 - Style related changes

>From v1 submission:

Slim Bootloader(SBL) [see link below] is a small open-source boot
firmware, designed for running on certain Intel platforms. SBL can be
thought-of as fulfilling the role of a minimal BIOS
implementation, i.e initializing the hardware and booting
Operating System.

This driver creates sysfs interfaces which allows user space entities
to trigger update of SBL firmware.

Acknowledgment: Initial draft of the driver code was authored by
Maurice Ma <maurice.ma@...el.com>
