From 88468f7e5307a132a612d619a73936d030339892 Mon Sep 17 00:00:00 2001 From: Yousong Zhou Date: Tue, 18 Apr 2017 20:59:52 +0800 Subject: armvirt: merge arm64 as subtarget 64 Original armvirt target is now subtarget 32. Other than that the built result should remain the same as before Besides old features already available with arm64, the new armvirt/64 subtarget will also have those features originally enabled for armvirt/32 with commit 44ecfc2 ("armvirt: new target") - 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 - DEBUG_BUGVERBOSE for debug purposes Signed-off-by: Yousong Zhou --- target/linux/armvirt/README | 22 ++++++++++++++-------- 1 file changed, 14 insertions(+), 8 deletions(-) (limited to 'target/linux/armvirt/README') diff --git a/target/linux/armvirt/README b/target/linux/armvirt/README index e99038197e..fba71a62f2 100644 --- a/target/linux/armvirt/README +++ b/target/linux/armvirt/README @@ -1,20 +1,21 @@ This is intended to be used with LEDE project to provide image for use with -QEMU arm-softmmu virt machine. +QEMU ARM virt machine.
