To improve the performance, We add some initial setting for smi larbs. there are two part: 1), Each port has the special ostd(outstanding) value in each larb. 2), Two general settings for each larb. a. THRT_UPDATE: the value in bits[7:4] of 0x24 is not so good. The HW default is 4, and we expect it is 5, thus, add a flag to update it. This is only a DE recommendatory value, not a actual issue. The register name(THRT_CON) means: throttling control, and the field RD_NU_LMT means: Read Non-ultra commands limit. This change means update the Read non-ultra command from 4 to 5 here. b. SW_FLAG: Set 1 to the FLAG register. this is only for helping debug. We could confirm if the larb is reset from this value is 1 or 0. In some SoC, this setting maybe changed dynamically for some special case like 4K, and this initial setting is enough in mt8195.

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.
