Hello, The EyeQ5 SoC from Mobileye is based on the MIPS I6500 architecture and features multiple controllers such as the classic UART, I2C, SPI, as well as CAN-FD, PCIe, Octal/Quad SPI Flash interface, Gigabit Ethernet, MIPI CSI-2, and eMMC 5.1. It also includes a Hardware Security Module, Functional Safety Hardware, and MJPEG encoder. One peculiarity of this SoC is that the physical address of the DDDR exceeds 32 bits. Given that the architecture is 64 bits, this is not an issue, but it requires some changes in how the mips64 is currently managed during boot. In this forth version there are now minor changes, mainly fixes for warning during build reported by build bot or find by myself when testing the mips32 build. I also made some modification in the /board-eyeq5.config and thanks to the setting of SPARSMEM I don't have any more the error message during boot when using low memory at 0x40000000. To build and test the kernel, we need to run the following commands: make 64r6el_defconfig BOARDS=eyeq5 make vmlinuz.itb Changelog: v3 -> v4: - Fix build warning in "MIPS: Get rid of CONFIG_NO_EXCEPT_FILL": check that we are in 64bit mode before using KSEG0 that exist only in this mode. - Modify "MIPS: spaces: Define a couple of handy macros" to be buildable in 32bit mode. - Use correct format specifier to print address in "MIPS: traps: Give more explanations if ebase doesn't belong to KSEG0" - In "MIPS: generic: Add support for Mobileye EyeQ5",remove CONFIG_ZBOOT_LOAD_ADDRESS from board-eyeq5.config, (as well as CONFIG_USE_XKPHYS that does not exist anymore) and add CONFIG_SPARSEMEM_MANUAL to enable SPRASMEM. v2 -> v3 - Added more reviewed-by and acked-by tags - Fix sorting for cpus entries in - Fix indentation issue in Documentation/devicetree/bindings/mips/mobileye.yaml v1 -> v2 - Added reviewed-by and acked-by tags - Fix typos reported - In patch 15 use 'img' vendor string instead of mti - In patch 16 modify licence - In patch 17 give more explanations about the block usage. - In patch 18, remove _ in node names, don't use anymore CONFIG_BUILTIN_DTB in Makefile, remove macro, modify licence. - In patch 19 remove most of the bootargs and only keeps earlycon. I also split the memory in 2 part in the device tree. - Integrate the series from Jiaxun Yang https://lore.kernel.org/linux-mips/20231027221106.405666-1-jiaxun.yang@flygoat.com/ They are patches 2 to 6 and 8 to 12 Then I added patch 7 to fix the cache issue visible on the Mobileye platform, I also add patch 13 to improve warning message when ebase doesn't belong to KSEG0 Regards, Gregory Gregory CLEMENT (13): MIPS: compressed: Use correct instruction for 64 bit code MIPS: spaces: Define a couple of handy macros MIPS: Fix cache issue with mips_cps_core_entry MIPS: traps: Give more explanations if ebase doesn't belong to KSEG0 dt-bindings: Add vendor prefix for Mobileye Vision Technologies Ltd. dt-bindings: mips: cpus: Sort the entries dt-bindings: mips: cpu: Add I-Class I6500 Multiprocessor Core dt-bindings: mips: Add bindings for Mobileye SoCs dt-bindings: mfd: syscon: Document EyeQ5 OLB MIPS: mobileye: Add EyeQ5 dtsi MIPS: mobileye: Add EPM5 device tree MIPS: generic: Add support for Mobileye EyeQ5 MAINTAINERS: Add entry for Mobileye MIPS SoCs Jiaxun Yang (9): MIPS: Export higher/highest relocation functions in uasm MIPS: genex: Fix except_vec_vi for kernel in XKPHYS MIPS: Fix set_uncached_handler for ebase in XKPHYS MIPS: Refactor mips_cps_core_entry implementation MIPS: Allow kernel base to be set from Kconfig for all platforms MIPS: traps: Handle CPU with non standard vint offset MIPS: Avoid unnecessary reservation of exception space MIPS: traps: Enhance memblock ebase allocation process MIPS: Get rid of CONFIG_NO_EXCEPT_FILL .../devicetree/bindings/mfd/syscon.yaml | 1 + .../devicetree/bindings/mips/cpus.yaml | 13 +- .../devicetree/bindings/mips/mobileye.yaml | 32 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 12 + arch/mips/Kconfig | 26 +- arch/mips/boot/compressed/head.S | 4 +- arch/mips/boot/dts/Makefile | 1 + arch/mips/boot/dts/mobileye/Makefile | 4 + arch/mips/boot/dts/mobileye/eyeq5-epm5.dts | 24 ++ .../boot/dts/mobileye/eyeq5-fixed-clocks.dtsi | 292 ++++++++++++++++++ arch/mips/boot/dts/mobileye/eyeq5.dtsi | 134 ++++++++ arch/mips/configs/generic/board-eyeq5.config | 41 +++ arch/mips/generic/Kconfig | 15 + arch/mips/generic/Platform | 2 + arch/mips/generic/board-epm5.its.S | 24 ++ arch/mips/include/asm/addrspace.h | 5 + arch/mips/include/asm/mach-generic/spaces.h | 2 + arch/mips/include/asm/mips-cm.h | 1 + arch/mips/include/asm/smp-cps.h | 4 +- arch/mips/include/asm/traps.h | 1 - arch/mips/include/asm/uasm.h | 2 + arch/mips/kernel/cps-vec.S | 110 +++---- arch/mips/kernel/cpu-probe.c | 5 - arch/mips/kernel/cpu-r3k-probe.c | 2 - arch/mips/kernel/genex.S | 19 +- arch/mips/kernel/head.S | 7 +- arch/mips/kernel/smp-cps.c | 171 ++++++++-- arch/mips/kernel/traps.c | 90 ++++-- arch/mips/mm/uasm.c | 6 +- 30 files changed, 893 insertions(+), 159 deletions(-) create mode 100644 Documentation/devicetree/bindings/mips/mobileye.yaml create mode 100644 arch/mips/boot/dts/mobileye/Makefile create mode 100644 arch/mips/boot/dts/mobileye/eyeq5-epm5.dts create mode 100644 arch/mips/boot/dts/mobileye/eyeq5-fixed-clocks.dtsi create mode 100644 arch/mips/boot/dts/mobileye/eyeq5.dtsi create mode 100644 arch/mips/configs/generic/board-eyeq5.config create mode 100644 arch/mips/generic/board-epm5.its.S
