From 29676833df1d9207cb665fe9869f6778a96045b9 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 28 Sep 2016 16:30:56 +0100 Subject: power: reset: Add Intel PIIX4 poweroff driver Add a driver which allows powering off the system via an Intel PIIX4 southbridge, by entering the PIIX4 SOff state. This is useful on the MIPS Malta development board, where it will power down the FPGA based board until its ON/NMI button is pressed, or the QEMU implementation of the MIPS Malta board where it will cause QEMU to exit.
