* Make sure to set board_rev for N2+ correctly
For some reason the code to set the environment did not make it into the
ODROID N2 board code. Fix the patch to correctly set board_rev for N2(+).
Also remove the w400 patch as it is no longer required.
* Use latest ODROID-N2+ patches
Use the queued patches (and fixes) for upstream ODROID-N2+ support.
This uses the clock settings from meson-g12b-a311d.dtsi running the
CPUs at the following clocks:
- 4xA73@2.2GHz
- 2xA53@1.8GHz
Instead of reverting the CDC ACM cool-down patch fix the intention of
that change. This should fix the error recovery paths in the CDC ACM
driver and allow CDC ACM devices to continue working even in the event
of USB issues.

* Bump ODROID boards to Linux 5.9.1
This makes quite some patches obsolete which since have been upstreamed.
* Drop Linux 5.7 header symbols
Since we do not introduce new packages which actually require a newer
kernel headers, there is no value in having config symbols for the new
kernel version. Buildroot is still using the headers from our kernel,
and hence gets the latest version of the headers.
The Docker socket path is /run/docker.sock. Also only one path can be
used per property. This fixes the supervisor service, which currently
refuses to start due to missing Docker socket.
The patch causes U-Boot freezes in some configurations. The root cause
is that U-Boot does not allow to use the bss section in pre-relocation
code (which is where the UART is used). Drop the patch as it is not
required currently.

The to symlink serial0/1 currently might apply to the first or second
ttyAMAX instance. In downstream, a patch makes sure that the first
PL011 is always ttyAMA0. However, upstream the numbering depends on the
UART alias, which leads to the first PL011 being ttyAMA1.
Check the actual iobase too to make sure we are dealing with the first
PL011 instance.

The new readline utilty used by the CLI add-on requires the size of the
terminal to be set. Use the resize command to initialize terminal size
on login if we are running on a serial terminal.
The U-Boot build system creates a ready to use idbloader.img. A earlier
commit dropped the HAOS code to create the same. However, the commit
missed copying the one built by U-Boot. Make sure idbloader.img gets
copied to the image output directory.
Currently the Microsoft Reserved Partition GUID is used for this FAT32
formatted partition. This GUID is a rather Microsoft Windows specific
GUID and not commonly used on Linux.
On Linux systems partitions of this type do not get automatically
mounted (see /usr/lib/udev/rules.d/80-udisks2.rules). However, since
this partition contains some files user commonly need to adjust
(config.txt, cmdline.txt) it would be good if the partition does get
mounted.
Use Microsoft Basic Data instead, which is used by default for FAT32
partition (even by Linux partitioning tools such as gparted). Tested
on ASUS Tinker Board and RPi4.
The hassos-expand script calls sfdisk to find free disk space. It seems
that today it considers the space before the first partition as free:
$ sudo sfdisk -Fq /dev/sdi
Start End Sectors Size
2048 16383 14336 7M
This causes the script to always resize. It seems not to cause harm to
the partition table (it does not resize really). However, the call to
partx seems to confuse systemd and kill the mnt-data.mount process
(presumably because udev causes remove/add events for the by-label
device units).
Consider everything below 8MiB to not be worthy of a size change. This
avoids missdetection and resize attempts where there is no need.
* Remove rk3288-xt-q8l-v10.dts related patches
We only support ASUS Tinker Board, so no need for those patches.
* Remove unnecessary patches and rebase some for Tinker Board S
Some patches only apply to the Tinker Board device tree. Rebase them to
apply to the dtsi file so they apply for both boards, the Tinker Board
and the Tinker Board S board.
Support custom output directories akin to how buildroot supports O=.
This allows to use separate output directory per board, e.g. using
make O=output_odroid-n2.
* Fix Tinker Board S (eMMC) boot (#650)
Use Tinker Board S U-Boot configuration which is capable to boot from
eMMC as well as from SD card.
Note that this makes U-Boot always claiming to run on Tinker Board S:
..
Model: Rockchip RK3288 Asus Tinker Board S
..
It seems that there is no generic Tinker Board configuration. However,
Tinker Board S configuration really seems to work well with Tinker Board
as well, so just use it.
Also today the U-Boot Makefile seems to generate a working idbloader.img
already. Drop our special handling.
* Use Tinker Board S device tree if booting from eMMC for Linux
Instead of patching the Tinker Board device tree, select the device tree
based on what device we are booting from.
Note: This boots the non-S device tree when booting a Tinker Board S
from SD card! But there is no reliable detection otherwise, so let's
just live with that fact.
* Document how to use our U-Boot to flash eMMC
Aligning partitions (and hence file system structures) to higher level
then 512 byte sectors is common practise and highly recommended for flash
backed block devices. It makes sure that the underlaying flash translation
layer (FTL) does not amplify writes due to missalignment of its erase
block size. Use a 1MiB boundary which is what a modern fdisk is doing.

This makes sure that the kernel module loop is loaded, the loop devices
under /dev have been created before the container starts. Docker uses
the current /dev as template for the container /dev. If the loop entries
are missing, loop devices can't be used inside the container. Use
losetup which does not make assumption weather loop support is built-in.
This fixes issues seen on my machine when entering the build environment
the first time after build:
mount: /mnt/data: failed to setup loop device for /export/data.ext4.
