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.

Remove code duplication and make sure to load socinfo only once. Also
set board_rev before MAC address to make sure board_rev is set even if
loading MAC address from efuses fails.

* Update buildroot-external/kernel/docker.config

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.
make[2]: *** [package/pkg-generic.mk:364: /build/buildroot/output_rpi4/build/hassio-1.0.0/.stamp_target_installed] Error 32
* Add ODROID-N2+ support
Add ODROID-N2+ support with the new SoC revision c. Extend the U-Boot
script: Assume ODROID-N2 if the SoC revision is "a" (there are only "a"
revision SoCs on ODROID N2) and assume N2+ otherwise.
Currently using overclock mode as proposed in the upstream kernel patches.
* Update hassos-hook.sh

* Backport USB PCIe/XHCI patches to U-Boot 2020.07
Backport relevant patches required to make PCIe/USB XHCI work.
* Backport/integrate PCIe device tree changes from upstream Linux
U-Boot uses the device tree provided by upstream Linux. Make sure the
device tree has the relevant chanages to make VL805 USB controller
reset work.
* Document RPi 4 USB mass storage support (#746)
Unfortunately builds for 32-bit seem to lead to freezes. Conservatively
only update to 2020.07 for 64-bit builds.
