Bean Huo ea834e6609 scsi: ufs: core: Add advanced RPMB support where UFSHCI 4.0 does not support EHS length in UTRD 
commit c91e585cfb upstream.

According to UFSHCI 4.0 specification:

5.2 Host Controller Capabilities Registers
5.2.1 Offset 00h: CAP – Controller Capabilities:

 "EHS Length in UTRD Supported (EHSLUTRDS): Indicates whether the host
  controller supports EHS Length field in UTRD.

  0 – Host controller takes EHS length from CMD UPIU, and SW driver use EHS
  Length field in CMD UPIU.

  1 – HW controller takes EHS length from UTRD, and SW driver use EHS
  Length field in UTRD.

  NOTE Recommend Host controllers move to taking EHS length from UTRD, and
  in UFS-5, it will be mandatory."

So, when UFSHCI 4.0 doesn't support EHS Length field in UTRD, we could use
EHS Length field in CMD UPIU. Remove the limitation that advanced RPMB only
works when EHS length is supported in UTRD.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
