MIPS: octeon: Include required header; fix octeon ethernet build

2019-10-02T17:08:20+00:00

Commit 171a9bae68c7 ("staging/octeon: Allow test build on !MIPS") moved the inclusion of a bunch of headers by various files in the Octeon ethernet driver into a common header, but in doing so it changed the order in which those headers are included. Prior to the referenced commit drivers/staging/octeon/ethernet.c included asm/octeon/cvmx-pip.h before asm/octeon/cvmx-ipd.h, which makes use of the CVMX_PIP_SFT_RST definition pulled in by the former. After commit 171a9bae68c7 ("staging/octeon: Allow test build on !MIPS") we pull in asm/octeon/cvmx-ipd.h first & builds fail with: In file included from drivers/staging/octeon/octeon-ethernet.h:27, from drivers/staging/octeon/ethernet.c:22: arch/mips/include/asm/octeon/cvmx-ipd.h: In function 'cvmx_ipd_free_ptr': arch/mips/include/asm/octeon/cvmx-ipd.h:330:27: error: storage size of 'pip_sft_rst' isn't known union cvmx_pip_sft_rst pip_sft_rst; ^~~~~~~~~~~ arch/mips/include/asm/octeon/cvmx-ipd.h:331:36: error: 'CVMX_PIP_SFT_RST' undeclared (first use in this function); did you mean 'CVMX_CIU_SOFT_RST'? pip_sft_rst.u64 = cvmx_read_csr(CVMX_PIP_SFT_RST); ^~~~~~~~~~~~~~~~ CVMX_CIU_SOFT_RST arch/mips/include/asm/octeon/cvmx-ipd.h:331:36: note: each undeclared identifier is reported only once for each function it appears in arch/mips/include/asm/octeon/cvmx-ipd.h:330:27: warning: unused variable 'pip_sft_rst' [-Wunused-variable] union cvmx_pip_sft_rst pip_sft_rst; ^~~~~~~~~~~ make[4]: *** [scripts/Makefile.build:266: drivers/staging/octeon/ethernet.o] Error 1 make[3]: *** [scripts/Makefile.build:509: drivers/staging/octeon] Error 2 Fix this by having asm/octeon/cvmx-ipd.h include the asm/octeon/cvmx-pip-defs.h header that it is reliant upon, rather than requiring its users to pull in that header before it.

Pull MIPS updates from Paul Burton: "Main MIPS changes: - boot_mem_map is removed, providing a nice cleanup made possible by the recent removal of bootmem. - Some fixes to atomics, in general providing compiler barriers for smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or MIPS32 systems using cmpxchg64(). - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo Frascino. - Removal of undefined behavior in set_io_port_base(), fixing the behavior of some MIPS kernel configurations when built with recent clang versions. - Initial MIPS32 huge page support, functional on at least Ingenic SoCs. - pte_special() is now supported for some configurations, allowing among other things generic fast GUP to be used. - Miscellaneous fixes & cleanups. And platform specific changes: - Major improvements to Ingenic SoC support from Paul Cercueil, mostly enabled by the inclusion of the new TCU (timer-counter unit) drivers he's spent a very patient year or so working on. Plus some fixes for X1000 SoCs from Zhou Yanjie. - Netgear R6200 v1 systems are now supported by the bcm47xx platform. - DT updates for BMIPS, Lantiq & Microsemi Ocelot systems" * tag 'mips_5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (89 commits) MIPS: Detect bad _PFN_SHIFT values MIPS: Disable pte_special() for MIPS32 with RiXi MIPS: ralink: deactivate PCI support for SOC_MT7621 mips: compat: vdso: Use legacy syscalls as fallback MIPS: Drop Loongson _CACHE_* definitions MIPS: tlbex: Remove cpu_has_local_ebase MIPS: tlbex: Simplify r3k check MIPS: Select R3k-style TLB in Kconfig MIPS: PCI: refactor ioc3 special handling mips: remove ioremap_cachable mips/atomic: Fix smp_mb__{before,after}_atomic() mips/atomic: Fix loongson_llsc_mb() wreckage mips/atomic: Fix cmpxchg64 barriers MIPS: Octeon: remove duplicated include from dma-octeon.c firmware: bcm47xx_nvram: Allow COMPILE_TEST firmware: bcm47xx_nvram: Correct size_t printf format MIPS: Treat Loongson Extensions as ASEs MIPS: Remove dev_err() usage after platform_get_irq() MIPS: dts: mscc: describe the PTP ready interrupt MIPS: dts: mscc: describe the PTP register range ...

MIPS: OCTEON: delete redundant register definitions

2018-12-04T23:57:30+00:00

For most OCTEON SoCs there is a repeated and redundant register definition for almost every hardware register, although the register bit fields would not differ from other SoCs. Since the driver code should use only one definition for simplicity, these other fields are just redundant and can be deleted.
