From aa38571246c6ac279ebebd141157297bcb959d76 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 22 Jun 2019 03:00:26 +0900 Subject: arm64: dts: uniphier: add reserved-memory for secure memory The memory regions specified by /memreserve/ are passed to early_init_dt_reserve_memory_arch() with nomap=false, so it is not suitable for reserving memory for Trusted Firmware-A etc. Use the more robust /reserved-memory node with the no-map property to prevent the kernel from mapping it.
