arm64 as Tier 1 for FreeBSD 13

[Mark Millard]

Here is how I updated a Rock64 bootable microsdcard to
also be able to boot an RPi4 (no file or disk usage
conflicts).

I took my Rock64 microsdcard and did the following,
using only FreeBSD and its ports. Note that /boot/efi/
is the msdos file system mount point for this
example. This sequence started on the Rock64:

Using the port sysutils/rpi-firmware and what it installs, I
did (ignore any messages from my habitual -aRx use):

cp -aRx /usr/local/share/rpi-firmware/ /boot/efi/
cp -aRx /boot/efi/config_rpi4.txt /boot/efi/config.txt

Then, using the port sysutils/u-boot-rpi4 and what it installs,
I did:

cp -aRx /usr/local/share/u-boot/u-boot-rpi4/u-boot.bin /boot/efi/

After shutting down the Rock64 I put the microsdcard in the
RPi4 and turned it on.

It booted fine:

# uname -apKU
FreeBSD Rock64OrRPI4 13.0-CURRENT FreeBSD 13.0-CURRENT #39 r356426M: Mon Jan  6 19:55:34 PST 2020     markmi at FBSDFHUGE:/usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64/sys/GENERIC-NODBG  arm64 aarch64 1300075 1300075

(I have a serial console configuration set up.)
