From 18250b43f7b6d0085724bf6fc186f9a107066068 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 11 Aug 2021 10:52:28 +0200 Subject: of: fdt: Remove early_init_dt_reserve_memory_arch() override capability Commit e7ae8d174eec0b3b ("MIPS: replace add_memory_region with memblock") removed the last architecture-specific override of early_init_dt_reserve_memory_arch(). Convert the common implementation from a weak global function to a static function.

However, no overrides ever emerged. Later, commit aca52c3983891060 ("mm: remove CONFIG_HAVE_MEMBLOCK") removed the non-memblock version. Remove early_init_dt_mark_hotplug_memory_arch(), and replace it by a direct call to memblock_mark_hotplug().
