Stefan Agner a0871be6c0 Bump buildroot to 2020.11-rc1 (#985)
* Update buildroot-patches for 2020.11-rc1 buildroot

* Update buildroot to 2020.11-rc1

Signed-off-by: Stefan Agner <stefan@agner.ch>

* Don't rely on sfdisk --list-free output

The --list-free (-F) argument does not allow machine readable mode. And
it seems that the output format changes over time (different spacing,
using size postfixes instead of raw blocks).

Use sfdisk json output and calculate free partition space ourselfs. This
works for 2.35 and 2.36 and is more robust since we rely on output which
is meant for scripts to parse.

* Migrate defconfigs for Buildroot 2020.11-rc1

In particular, rename BR2_TARGET_UBOOT_BOOT_SCRIPT(_SOURCE) to
BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT(_SOURCE).

* Rebase/remove systemd patches for systemd 246

* Drop apparmor/libapparmor from buildroot-external

* hassos-persists: use /run as directory for lockfiles

The U-Boot tools use /var/lock by default which is not created any more
by systemd by default (it is under tmpfiles legacy.conf, which we no
longer install).

* Disable systemd-update-done.service

The service is not suited for pure read-only systems. In particular the
service needs to be able to write a file in /etc and /var. Remove the
service. Note: This is a static service and cannot be removed using
systemd-preset.

* Disable apparmor.service for now

The service loads all default profiles. Some might actually cause
problems. E.g. the profile for ping seems not to match our setup for
/etc/resolv.conf:
[85503.634653] audit: type=1400 audit(1605286002.684:236): apparmor="DENIED" operation="open" profile="ping" name="/run/resolv.conf" pid=27585 comm="ping" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

PINE64 ROCKPro64
================
https://www.pine64.org/rockpro64/

Build:
======
  $ make rockpro64_defconfig
  $ make

Creating bootable SD card:
==========================

Simply invoke (as root)

sudo dd if=output/images/sdcard.img of=/dev/sdX && sync

Where X is your SD card device.

Booting:
========
RockPro64 has a 40-pin PI-2 GPIO Bus.

Connect a jumper between pin 23 and pin 25 for SD card boot.

Serial console:
---------------
The pin layout for serial console on PI-2 GPIO Bus is as follows:

pin 6:  gnd
pin 8:  tx
pin 10: rx

Initially connect pin 6 and pin 8(transmit). Apply power to RockPro64, once the
power is on then connect pin 10(receive).

Baudrate for this board is 1500000.

Login:
------
Enter 'root' as login user, and the prompt is ready.
