From f2653e8dd92229328480da35c26e6f9fbfec4381 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 3 Jun 2015 09:20:05 +0800 Subject: x86: coreboot: Control I/O port 0xb2 writing via device tree Writing 0xcb to I/O port 0xb2 (Advanced Power Management Control) causes U-Boot to hang on QEMU q35 target. We introduce a config option in the device tree "u-boot,no-apm-finalize" under /config node if we don't want to do that.
