From 63c0941726e44f31c42de744a57f528fee2df88f Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 26 Nov 2016 11:02:10 +0900 Subject: libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt(). It will be useful when we want to use a memory node from a kernel DTB as is, but need some fixups for Spin-Table/PSCI.
