Rasmus, Since the patches also touched net and serial subsystem. Can you also repost these patches(maybe just related ones) onto netdev and linux-serial mailing list?

There have been several attempts in the past few years to allow building the QUICC engine drivers for platforms other than PPC. This is yet another attempt. v3 can be found here: https://lore.kernel.org/lkml/20191101124210.14510-1-linux@rasmusvillemoes.dk/ v4 adds a some patches to fix (ab)use of IS_ERR_VALUE which fails when sizeof(u32) != sizeof(long), i.e. on 64-bit platforms. Freescale drivers are some of the last holdouts using that macro (outside of arch/ and core mm code), so I decided trying to simply get rid of it instead of papering over it by using a temporary long to store the result in. Doing that I stumbled on some other things that should be fixed. These are the new patches 34-45. Patch 35 from v3 (which added a PPC32 dependency to FSL_UCC_HDLC) is gone from this version, so that that driver can indeed now be built for arm and arm64. 1-5 are about replacing in_be32 etc. in the core QE code (drivers/soc/fsl/qe). 6-8 handle miscellaneous other ppcisms. 9-21 deal with qe_ic: Simplifying the driver significantly by removing unused code, and removing the platform-specific initialization from arch/powerpc/. 22-25 deal with raw access to devicetree properties in native endianness. 26-33 makes drivers/tty/serial/ucc_uart.c (CONFIG_SERIAL_QE) ready to build on arm. 34-45 deal with IS_ERR_VALUE() and some other things found while digging around that part of the code. 46 adds a PPC32 dependency to UCC_GETH - it has some of the same issues that have been fixed in the ucc_uart and ucc_hdlc cases. Nobody has requested that I allow that driver to be built for arm{,64}, so instead of growing this series even bigger, I kept that addition. It's trivial to remove if somebody cares enough to fix the build errors/warnings and actually has a platform to test the result on. Finally patch 47 lifts the PPC32 restriction from QUICC_ENGINE. At the request of Li Yang, it doesn't remove the PPC32 dependency but instead changes it to PPC32 || ARM || ARM64 (or COMPILE_TEST), i.e. listing the platforms that may have a QE. The series has been built and booted on both an mpc8309-based platform (ppc) as well as an ls1021a-based platform (arm). The core QE code is exercised on both, while I could only test the ucc_uart on arm, since the uarts are not wired up on our mpc8309 board. Qiang Zhao reports that the ucc_hdlc driver does indeed work on a ls1043ardb (arm64) board, I hope he'll formally add a Tested-by: to the relevant patches since I don't have any arm64 board with QE.
