From d9df9fb901d25b941ab2cfb5b570d91fb2abf7a3 Mon Sep 17 00:00:00 2001 From: Yasha Cherikovsky Date: Tue, 25 Sep 2018 21:08:25 +0300 Subject: [PATCH] MIPS: Octeon: Remove special handling of CONFIG_MIPS_ELF_APPENDED_DTB=y The ELF appended dtb can be accessed now via 'fw_passed_dtb'. Since raw appended dtb is accessed via that variable too, this now effectively allows to boot with CONFIG_MIPS_RAW_APPENDED_DTB=y on Octeon.
