This patch series adds support for the kv3-1 CPU architecture of the kvx family
found in the Coolidge (aka MPPA3-80) SoC of Kalray.

This is an RFC, since kvx support is not yet upstreamed into gcc/binutils,
therefore this patch series cannot be merged into Linux for now.

The goal is to have preliminary reviews and to fix problems early.

The Kalray VLIW processor family (kvx) has the following features:
* 32/64 bits execution mode
* 6-issue VLIW architecture
* 64 x 64bits general purpose registers
* SIMD instructions
* little-endian
* deep learning co-processor

Kalray kv3-1 core which is the third of the kvx family is embedded in Kalray
Coolidge SoC currently used on K200 and K200-LP boards.

The Coolidge SoC contains 5 clusters each of which is made of:
* 4MiB of on-chip memory (SMEM)
* 1 dedicated safety/security core (kv3-1 core).
* 16 PEs (Processing Elements) (kv3-1 cores).
* 16 Co-processors (one per PE)
* 2 Crypto accelerators

The Coolidge SoC contains the following features:
* 5 Clusters
* 2 100G Ethernet controllers
* 8 PCIe GEN4 controllers (Root Complex and Endpoint capable)
* 2 USB 2.0 controllers
* 1 Octal SPI-NOR flash controller
* 1 eMMC controller
* 3 Quad SPI controllers
* 6 UART
* 5 I2C controllers (3 of which are SMBus capable)
* 4 CAN controllers
* 1 OTP memory

A kvx toolchain can be built using:
# install dependencies: texinfo bison flex libgmp-dev libmpc-dev libmpfr-dev
$ git clone https://github.com/kalray/build-scripts
$ cd build-scripts
$ source last.refs
$ ./build-kvx-xgcc.sh output

The kvx toolchain will be installed in the "output" directory.

You can also find prebuilt toolchains at: https://github.com/kalray/build-scripts/releases/tag/v4.11.1
They are built for Ubuntu 18.04, 20.04 and 22.04 (named 'latest').

A buildroot image (kernel+rootfs) and toolchain can be built using:
$ git clone -b coolidge-for-upstream-v2 https://github.com/kalray/buildroot
$ cd buildroot
$ make O=build_kvx kvx_defconfig
$ make O=build_kvx

The vmlinux image can be found in buildroot/build_kvx/images/vmlinux.

If you are just interested in building the Linux kernel with no rootfs you can
just do this with the kvx-elf- toolchain:
$ make ARCH=kvx O=build_kvx CROSS_COMPILE=kvx-elf- defconfig
$ make ARCH=kvx O=build_kvx CROSS_COMPILE=kvx-elf- -j$(($(nproc) + 1))

The vmlinux ELF can be run with qemu by doing:
# install dependencies: ninja pkg-config libglib-2.0-dev cmake libfdt-dev libpixman-1-dev zlib1g-dev
$ git clone https://github.com/kalray/qemu-builder
$ cd qemu-builder
$ git submodule update --init
$ make -j$(($(nproc) + 1))
$ ./qemu-system-kvx -m 1024 -nographic -kernel <path/to/vmlinux>

V1 -> V2:
 - Rebase on 6.1.6
 - Removed features that are non-necessary for basic port to boot: kgdb, l2 cache driver, jump label, ftrace, hw breakpoints, gdb python helpers and perf monitors
 - Split dt bindings in separate patches
 - Split irqchip drivers: 1 driver == 1 patch
 - Fixed typos in arch/kvx/Kconfig
 - Rewrote ASM atomic helpers in C using builtins
 - Documentation has been rewritten in RST format and included in documentation build system
 - Renamed default_defconfig to defconfig
 - Removed arch-specific __access_ok to use generic code
 - Fixed make clean issue caused by LIBGCC definition in arch/kvx/Makefile

Note that all remarks on V1 patchset are not addressed yet. We are still working on some fixes like removing legacy syscalls,
using generic entry, rework smp.c and publication of kv3-1 ABI specification.
