We used to map the dtb differently between early_pg_dir and swapper_pg_dir which caused issues when we referenced addresses from the early mapping with swapper_pg_dir (reserved_mem): move the dtb mapping to the fixmap region in patch 1, which allows to simplify dtb handling in patch 2.
base-commit-tag: v6.1.24
Changes in v2: - Add missing SoB
Alexandre Ghiti (3): riscv: Move early dtb mapping into the fixmap region riscv: Do not set initial_boot_params to the linear address of the dtb riscv: No need to relocate the dtb as it lies in the fixmap region
