Merge tag 'riscv-for-linus-5.8-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt: - The remainder of the code necessary to support the Kendryte K210: * Support for building device trees into the kernel, as the K210 doesn't have a bootloader that provides one * A K210 device tree and the associated defconfig update * Support for skipping PMP initialization on systems that trap on PMP accesses rather than treating them as WARL - Support for KGDB - Improvements to text patching - Some cleanups to the SiFive L2 cache driver * tag 'riscv-for-linus-5.8-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: soc: sifive: l2 cache: Mark l2_get_priv_group as static soc: sifive: l2 cache: Eliminate an unsigned zero compare warning riscv: Add support to determine no. of L2 cache way enabled riscv: cacheinfo: Implement cache_get_priv_group with a generic ops structure riscv: Use text_mutex instead of patch_lock riscv: Use NOKPROBE_SYMBOL() instead of __krpobes annotation riscv: Remove the 'riscv_' prefix of function name riscv: Add SW single-step support for KDB riscv: Use the XML target descriptions to report 3 system registers riscv: Add KGDB support kgdb: Add kgdb_has_hit_break function RISC-V: Skip setting up PMPs on traps riscv: K210: Update defconfig riscv: K210: Add a built-in device tree riscv: Allow device trees to be built into the kernel
