This is yet another attempt. Changes in v3: - Address the performance impact on ppc from replacing out_be32 by iowrite32be by instead introducing a qe_iowrite32be wrapper and using that - patches 3 and 4 in this series. - Extend the series so that both the QE core as well as ucc_uart builds for ARM - patches 26-33. - Reorganize things a bit to avoid touching code that gets killed anyway in a later patch. Also the patches are now better grouped: 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. 34-36 remove the PPC32 dependency from QUICC_ENGINE. Two drivers that depend on QUICC_ENGINE get an explicit PPC32 dependency to prevent allmodconfig build failures. 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.
