Add support for firmware updates via RAUC on aarch64. The created RAUC
bundle (images/infix-$BR2_ARCH.pkg) is signed with the same key used
to sign the raw FIT image.
mkimage will generate an FIT image containing a signature of the
rootfs, where the data is kept out of the DTB data structure, i.e.:
.---------.
| DTB |
:---------:
| Padding |
:---------:
| |
| |
| rootfs |
| |
| |
'---------'
This is the on-disk format of Infix. At boot, we extract kernel and
device trees from the rootfs, and then use Linux's device mapper to
create a virtual block device that exposes the rootfs (squash).
This change checks¹ if the system does not have a br0 interface, creates
a default one consisting of all switch ports in VLAN 1 of br0.
On top of br0 a vlan1 management interface is created with DHCP address.
For emulation and test purposes, a way to supply tap interfaces from
Qemu, and pass off as if they were regular switch ports, is added.

¹ obviously a better way to detect a factory-reset device is needed,
not all systems running infix will need or want a br0 interface.

This change replaces the BusyBox ifup/ifdown applets with the full-blown
ifupdown2 package. To get it fully working we also need to enable a few
missing kernel features: ipv4 + ipv6, multiple routing tables, and some
netfilter features. We take the opportunity to sync kernel features in
between the two archs as well.

Set up bridge first:
root@infix:~# ip link set dev eth0 up
root@infix:~# ip link set dev eth1 up
root@infix:~# ip link set dev eth2 up
root@infix:~# ip link set dev eth3 up
root@infix:~# ip link add name br0 type bridge
root@infix:~# ip link set dev eth0 master br0
root@infix:~# ip link set dev eth1 master br0
root@infix:~# ip link set dev eth2 master br0
root@infix:~# ip link set dev eth3 master br0
Start MRP server and add a configuration:
root@infix:~# mrp_server &
root@infix:~# mrp addmrp bridge br0 ring_nr 1 pport eth0 sport eth1 ring_role mrm
root@infix:~# mrp addmrp bridge br0 ring_nr 2 pport eth2 sport eth3 ring_role mrm
root@infix:~# mrp getmrp
bridge: br0 ring_nr: 1 pport: eth0 sport: eth1 ring_role: MRM ring_state: CHK_RO
bridge: br0 ring_nr: 2 pport: eth2 sport: eth3 ring_role: MRM ring_state: CHK_RC
Once all rings are set up:
root@infix:~# ip link set dev br0 up
