Certain SoCs require the PCIe outbound mapping to be configured in software. Add support for those chips. [jonmason: Use %pap format when printing size_t to avoid warnings in 32-bit build.] [arnd: Use div64_u64() instead of "%" to avoid __aeabi_uldivmod link error in 32-bit build.] Signed-off-by: Ray Jui <rjui@broadcom.com> Signed-off-by: Jon Mason <jonmason@broadcom.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
