Petr Štetiar 472b8fc91b armvirt,x86: fix build breakage of crypto ccp module Upstream in commit f9f8f0c24203 ("crypto: ccp -- don't "select" CONFIG_DMADEVICES") removed dependency on CONFIG_DMADEVICES symbol which leads to build breakage of ccp crypto module, so fix this by adding that symbol back in the kernel config.

README

This is intended to be used with LEDE project to provide image for use with
QEMU ARM virt machine.

Run with qemu-system-arm

	# boot with initramfs embedded in
	qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage-initramfs

	# boot with accel=kvm
	qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
	openwrt-armvirt-32-zImage-initramfs

	# boot with a separate rootfs
	qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
	  -drive file=openwrt-armvirt-32-root.ext4,format=raw,if=virtio -append 'root=/dev/vda rootwait'

	# boot with local dir as rootfs
	qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
	  -fsdev local,id=rootdev,path=root-armvirt/,security_model=none \
	  -device virtio-9p-pci,fsdev=rootdev,mount_tag=/dev/root \
	  -append 'rootflags=trans=virtio,version=9p2000.L,cache=loose rootfstype=9p'

Run with kvmtool

	# start a named machine
	lkvm run -k openwrt-armvirt-32-zImage -i openwrt-armvirt-32-rootfs.cpio --name armvirt0

	# start with virtio-9p rootfs
	lkvm run -k openwrt-armvirt-32-zImage -d root-armvirt/

	# stop "armvirt0"
	lkvm stop --name armvirt0

	# stop all
	lkvm stop --all

The multi-platform ARMv8 target can be used with QEMU:

	qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
		-kernel openwrt-armvirt-64-Image-initramfs \
