MIPS: OCTEON: Replace SIZEOF_FIELD() macro

2019-12-09T18:33:50+00:00

Switch to the standard sizeof_field() macro to find the size of a member of a struct and remove the custom SIZEOF_FIELD() macro.

Delete board-specific link status. This info should now come from the DT only. Signed-off-by: Aaro Koskinen Signed-off-by: Paul Burton Cc: linux-mips@vger.kernel.org

MIPS: OCTEON: don't lie about interface type of CN3005 board

The fixed-link node in the DT should now take care of the link status, so this hack can be deleted. Signed-off-by: Aaro Koskinen Signed-off-by: Paul Burton Cc: linux-mips@vger.kernel.org

MIPS: OCTEON: delete SMI/MDIO enable

2019-01-28T23:17:39+00:00

SMI/MDIO enable is handled by the OCTEON MDIO driver, so we can delete the duplicated functionality from the platform code. Signed-off-by: Aaro Koskinen Signed-off-by: Paul Burton Cc: linux-mips@vger.kernel.org

Pull MIPS fixes from Paul Burton: "A few early MIPS fixes for 4.21: - The Broadcom BCM63xx platform sees a fix for resetting the BCM6368 ethernet switch, and the removal of a platform device we've never had a driver for. - The Alchemy platform sees a few fixes for bitrot that occurred within the past few cycles. - We now enable vectored interrupt support for the MediaTek MT7620 SoC, which makes sense since they're supported by the SoC but in this case also works around a bug relating to the location of exception vectors when using a recent version of U-Boot. - The atomic64_fetch_*_relaxed() family of functions see a fix for a regression in MIPS64 kernels since v4.19. - Cavium Octeon III CN7xxx systems will now disable their RGMII interfaces rather than attempt to enable them & warn about the lack of support for doing so, as they did since initial CN7xxx ethernet support was added in v4.7. - The Microsemi/Microchip MSCC SoCs gain a MAINTAINERS entry. - .mailmap now provides consistency for Dengcheng Zhu's name & current email address" * tag 'mips_fixes_4.21_1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MIPS: OCTEON: mark RGMII interface disabled on OCTEON III MIPS: Fix a R10000_LLSC_WAR logic in atomic.h MIPS: BCM63XX: drop unused and broken DSP platform device mailmap: Update name spelling and email for Dengcheng Zhu MIPS: ralink: Select CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8 MAINTAINERS: Add a maintainer for MSCC MIPS SoCs MIPS: Alchemy: update dma masks for devboard devices MIPS: Alchemy: update cpu-feature-overrides MIPS: Alchemy: drop DB1000 IrDA support bits MIPS: alchemy: cpu_all_mask is forbidden for clock event devices MIPS: BCM63XX: fix switch core reset on BCM6368

MIPS: OCTEON: mark RGMII interface disabled on OCTEON III

2019-01-02T22:17:24+00:00

Commit 885872b722b7 ("MIPS: Octeon: Add Octeon III CN7xxx interface detection") added RGMII interface detection for OCTEON III, but it results in the following logs: [ 7.165984] ERROR: Unsupported Octeon model in __cvmx_helper_rgmii_probe [ 7.173017] ERROR: Unsupported Octeon model in __cvmx_helper_rgmii_probe The current RGMII routines are valid only for older OCTEONS that use GMX/ASX hardware blocks. On later chips AGL should be used, but support for that is missing in the mainline. Until that is added, mark the interface as disabled.

Pull MIPS updates from Paul Burton: "Here's the main MIPS pull for Linux 4.21. Core architecture changes include: - Syscall tables & definitions for unistd.h are now generated by scripts, providing greater consistency with other architectures & making it easier to add new syscalls. - Support for building kernels with no floating point support, upon which any userland attempting to use floating point instructions will receive a SIGILL. Mostly useful to shrink the kernel & as preparation for nanoMIPS support which does not yet include FP. - MIPS SIMD Architecture (MSA) vector register context is now exposed by ptrace via a new NT_MIPS_MSA regset. - ASIDs are now stored as 64b values even for MIPS32 kernels, expanding the ASID version field sufficiently that we don't need to worry about overflow & avoiding rare issues with reused ASIDs that have been observed in the wild. - The branch delay slot "emulation" page is now mapped without write permission for the user, preventing its use as a nice location for attacks to execute malicious code from. - Support for ioremap_prot(), primarily to allow gdb or other ptrace users the ability to view their tracee's memory using the same cache coherency attribute. - Optimizations to more cpu_has_* macros, allowing more to be compile-time constant where possible. - Enable building the whole kernel with UBSAN instrumentation. - Enable building the kernel with link-time dead code & data elimination. Platform specific changes include: - The Boston board gains a workaround for DMA prefetching issues with the EG20T Platform Controller Hub that it uses. - Cleanups to Cavium Octeon code removing about 20k lines of redundant code, mostly unused or duplicate register definitions in headers. - defconfig updates for the DECstation machines, including new defconfigs for r4k & 64b machines. - Further work on Loongson 3 support. - DMA fixes for SiByte machines" * tag 'mips_4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (95 commits) MIPS: math-emu: Write-protect delay slot emulation pages MIPS: Remove struct mm_context_t fp_mode_switching field mips: generate uapi header and system call table files mips: add system call table generation support mips: remove syscall table entries mips: add +1 to __NR_syscalls in uapi header mips: rename scall64-64.S to scall64-n64.S mips: remove unused macros mips: add __NR_syscalls along with __NR_Linux_syscalls MIPS: Expand MIPS32 ASIDs to 64 bits MIPS: OCTEON: delete redundant register definitions MIPS: OCTEON: cvmx_gmxx_inf_mode: use oldest forward compatible definition MIPS: OCTEON: cvmx_mio_fus_dat3: use oldest forward compatible definition MIPS: OCTEON: cvmx_pko_mem_debug8: use oldest forward compatible definition MIPS: OCTEON: octeon-usb: use common gpio_bit definition MIPS: OCTEON: enable all OCTEON drivers in defconfig mips: annotate implicit fall throughs MIPS: Hardcode cpu_has_mips* where target ISA allows MIPS: MT: Remove norps command line parameter MIPS: Only include mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y ...
