Linux kernel source tree
aba2b17810
Looking at section "11.4.4.29 USP_PCIE_RESBAR Registers Summary" in the Technical Reference Manual (TRM) for RK3588, we can see that none of the BARs are Fixed BARs, but actually Resizable BARs. I couldn't find any reference in the TRM for RK3568, but looking at the downstream PCIe endpoint driver, both RK3568 and RK3588 are treated as the same, so the BARs on RK3568 must also be Resizable BARs. Now when we actually have support for Resizable BARs, let's configure these BARs as such.

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.
