From 44ecfc26eb22ca23668a5fd0c706d75f274e410a Mon Sep 17 00:00:00 2001 From: Yousong Zhou Date: Thu, 8 Dec 2016 23:21:30 +0800 Subject: [PATCH] armvirt: new target An ARM Cortex-A15 machine provided by QEMU. Kernel drivers enabled: - pl011, uart - pl031, rtc - pl061, gpio - pci-host-generic - virtio_{mmio,pci,net,blk,scsi,9p,console,balloon} - smp with NR_CPUS=4 - cpu-hotplug - ext4 - neon, vfp extensions support (otherwise userland will fail with illegal instruction signal (code 0x00000004)) - DEBUG_BUGVERBOSE for debug purposes Signed-off-by: Yousong Zhou --- target/linux/armvirt/Makefile | 28 ++
