Needed by, e.g., new swup script, but also everything else we might want
to do with jq in any sane way.

Latest Buildroot now has mdio-tools in mainline. This is useful when
debugging devices attaced over MDIO interfaces, eg. switches.

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.

- Drop Cortex A72 in favor of more general A53 images
- Enable device trees for all supported EspressoBIN models
- Bump kernel to latest 6.0
- Currently only starts from SD card, so add genimage to post-build
- Create Ext2/4 disk image for SD card
- Add infix-rw partition to sd-card image
- The genimage tool needs genext2fs to create rw.ext4

Upstream device trees specify regular PSCI support for SparX-5i, but
the U-Boot that Microchip ships does not actually support it.
Therefore, wrap the upstream version to disable PSCI and revert to
spin tables for SMP bringup.
OpenSSH also enable OpenSSL and ZLIB, both of which we'll need later.
This in turn means Net-SNMP no longer needs its built-in OpenSSL stub.

- chrony will be used as NTP v3/v4 server
- dnsmasq will serve as a DNS forwarder and DHCP server when the
very basic BusyBox DHCP server is insufficient
- mstpd provides RSTP support
- ssdp-responder provides device discovery in Windows
- watchdogd provides basic system supervision and reset cause logging

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

The Buildroot linux_defconfig doesn't have CONFIG_OVERLAY_FS, which we
need for our shared rootfs overlay.

Initial defconfig is based on Buildroot qemu_x86_64_defconfig, with a
Bootlin pre-built toolchain and a very basic qemu.sh script, generated
by a local post-image.sh, for `make run`.
