Some platforms like TI's K2G have a restriction that the host side buffer address should be aligned to either 1MB/2MB/4MB or 8MB addresses depending on how it is configured in the endpoint (Ref: 11.14.4.9.1 Outbound Address Translation in K2G TRM SPRUHY8F January 2016 – Revised May 2017). This restriction also applies to the MSI addresses provided by the RC. However it's not possible for the RC to know about this restriction and it may not provide 1MB/2MB/4MB or 8MB aligned address. So MSI interrupts should be disabled even if the K2G EP has MSI capabiltiy register. Add support to not enable MSI interrupts in pci_endpoint_test driver so that it can be used to test K2G EP.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
