[-fixes,0/2] Fixes for dtb mapping

Message

Alexandre Ghiti March 23, 2023, 4:33 p.m. UTC

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
