For v2 hw, STP link from target is rejected after host reset because of a SoC bug. The STP reject will be terminated after we have sent IO from each PHY of a port. This is not an problem before, as we don't need to setup STP link from target immediately after host reset. But now, it is. Because we want to send soft-reset immediately after host reset. In order to terminate STP reject quickly, this patch send ATA reset command through each PHY of a port. Notes: ATA reset command don't need target's response. Besides, we do abort dev for each device before terminating STP reject. This is a quirk of v2 hw.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
