[PATCH 6.2.11 0/3] Fixes for dtb mapping

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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: v6.2.11

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
