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: v6.3-rc3
Alexandre Ghiti (2):
riscv: Move early dtb mapping into the fixmap region
riscv: Do not set initial_boot_params to the linear address of the dtb
