From f1581626071c8e37c58c5e8f0b4126b17172a211 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti alexghiti@rivosinc.com Date: Wed, 29 Mar 2023 10:19:31 +0200 Subject: [PATCH] riscv: Do not set initial_boot_params to the linear address of the dtb
early_init_dt_verify() is already called in parse_dtb() and since the dtb address does not change anymore (it is now in the fixmap region), no need to reset initial_boot_params by calling early_init_dt_verify() again.
