From 1fc72ff0d3fc38759bd050420eefc7aabc18936d Mon Sep 17 00:00:00 2001 From: Guodong Xu Date: Sun, 20 Sep 2026 03:18:26 -0400 Subject: [PATCH] riscv: dts: spacemit: k1: Add Zic64b ISA extension The K1 X60 cores have 64-byte cache blocks, described by their cbom/cbop/cboz-block-size of 64, so they implement Zic64b. Declare it in each core's riscv,isa-extensions and in the deprecated riscv,isa string.
