From 7b0a911478c74ca02581d496f732c10e811e894f Mon Sep 17 00:00:00 2001 From: Dave Young Date: Tue, 31 Jan 2017 13:21:40 +0000 Subject: efi/x86: Move the EFI BGRT init code to early init code Before invoking the arch specific handler, efi_mem_reserve() reserves the given memory region through memblock. efi_bgrt_init() will call efi_mem_reserve() after mm_init(), at which time memblock is dead and should not be used anymore. The EFI BGRT code depends on ACPI initialization to get the BGRT ACPI table, so move parsing of the BGRT table to ACPI early boot code to ensure that efi_mem_reserve() in EFI BGRT code still use memblock safely.
