The existing implementation of the TxFIFO resizing logic only supports scenarios where more than one port RAM is used. However, there is a need to resize the TxFIFO in USB2.0-only mode where only a single port RAM is available. This commit introduces the necessary changes to support TxFIFO resizing in such scenarios by adding a missing check for single port RAM. This fix addresses certain platform configurations where the existing TxFIFO resizing logic does not work properly due to the absence of support for single port RAM. By adding this missing check, we ensure that the TxFIFO resizing logic works correctly in all scenarios, including those with a single port RAM.

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 reStructuredText 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.
