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`.
