Subject: Re: [PATCH v5 1/3] arm64: map FDT as RW for early_init_dt_scan()

Quoting Hsin-Yi Wang (2019-05-26 21:33:34)
> Currently in arm64, FDT is mapped to RO before it's passed to
> early_init_dt_scan(). However, there might be some codes
> (eg. commit "fdt: add support for rng-seed") that need to modify FDT
> during init. Map FDT to RO after early fixups are done.
