Some platforms (like dra7xx) require only the least 28 bits of the corresponding 32 bit CPU address to be programmed in the address translation unit. This modified address is stored in io_base/mem_base/ cfg0_base/cfg1_base in dra7xx_pcie_host_init(). While this is okay for host mode where the address range is fixed, device mode requires different addresses to be programmed based on the host buffer address. Add a new ops to get the least 28 bits of the corresponding 32 bit CPU address and invoke it before programming the address translation unit.

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.
