-eMMC support is provided with the same image. Just flash the image to the eMMC by connecting your Tinker Board S to your PC via Micro-USB. Refer to the Tinkerboard documentation how-to flash using Micro-USB and UMS.
-
-The Home Assistant OS provided U-Boot does support UMS as well,
-however manual intervention is necessary:
-
- 1. Set the jumper between Micro-USB and HDMI the maskrom mode
- 2. Insert SD card and connect the board via Micro-USB to your PC
- 3. Continusly press Ctrl+C to interrupt boot
- 4. Set the jumper back to the park position
- 5. Start UMS using:
-```
-ums 0 mmc 0
-```
- 6. A mass storage device should appear. Flash Home Assistant OS to it.
+eMMC support is provided transparently. Just flash the image to the eMMC by connecting your Tinker Board S to your PC via Micro-USB.

-## Using datactl to move the data partition.
-
-In a Home Assistant OS installation, the data is stored on the `/mnt/data` partition of the SD card. This is the only read+write partition on the SD drive. Using the `datactl` move command, this partition can be moved off of the SD card onto an externally connected drive, leaving the rest of the read-only system on the SD.
-
-The storage capacity of the external drive must be larger than the storage capacity of the existing SD card.
-
-The command needs to be run from the host console by either connecting a keyboard and monitor or making use of the [debug ssh access](https://developers.home-assistant.io/docs/operating-system/debugging/) over port 22222. The command will not work from within an SSH add-on container.
-
-Log in as `root` to get to the Home Assistant CLI and then enter `login` to continue to the host.
-
-Confirm your USB SSD/HD is connected and recognized using `fdisk -l`.
-
-It is recommended to use fdisk to remove the existing partition(s) before proceeding.
-
-- Type `fdisk /dev/XXX` (replacing XXX with your drive)
-- Type `d` to delete a partition.
-- Continue if needed, then write the changes.
-
-Creating a new partition is not necessary.
-
-With the drive now prepared, use the below command (again, replacing XXX with your drive)
+This partition can be offloaded to a different drive with the utility:
 
 ```sh
 $ datactl move /dev/xxx
 ```
 
-Hit any key to continue, and then the move will happen after the next reboot. Once complete, the external drive will be owned and used by the system.
+On next boot, the partition will be moved to the new drive. The drive needs to be bigger as the old one and we own the full new drive.

+Subject: [PATCH 06/28] ARM: dts: rockchip: add the MiQi board's fan definition
+
+The MiQi board is sold with an enclosure in which a fan is connected
+to the second LED output, and configured by default in "heartbeat"
+mode so that it rotates slowly and increases when the CPU load
+increases, ensuring appropriate cooling by default. This LED output
+is called "Fan" in the original kernel and connected to GPIO18
+(gpiochip 0, pin 18). Here we called it "miqi:green:fan" to stay
+consistent with the kernel's naming conventions.
+
+It's worth noting that without this patch the fan doesn't work at
+all, risking to make the board overheat.

+Subject: [PATCH] ARM: DTS: rk3288-tinker: Enabling SDIO and Wifi
+
+Adding the appropriate nodes in order to exploit the WiFi capabilities
+of the board.
+Since these capabilities are provided through SDIO, and the SDIO
+nodes were not defined, these were added too.
+
+These seems to depend on each other so they are added in one big
+patch.
+
+Split if necessary.

-Subject: [PATCH 11/11] clk: meson: g12a: mark fclk_div2 as critical
-
-On Amlogic Meson G12b platform, similar to fclk_div3, the fclk_div2
-seems to be necessary for the system to operate correctly as well.
-
-Typically, the clock also gets chosen by the eMMC peripheral. This
-probably masked the problem so far. However, when booting from a SD
-card the clock seems to get disabled which leads to a system freeze.
-
-Let's mark this clock as critical, fixing boot from SD card on G12b
-platforms.

-Subject: [PATCH 3/4] ARM: dts: bcm2711: Add reset controller to xHCI node
-
-The chip is hardwired to the board's PCIe bus and needs to be properly
-setup trough a firmware routine after a PCI fundamental reset. Pass the
-reset controller phandle that takes care of triggering the
-initialization to the relevant PCI device.

- array initialization
-
-In current code there is no cache flush after initializing the scratchpad
-buffer array with the scratchpad buffer pointers. This leads to a failure
-of the "slot enable" command on the rpi4 board (Broadcom STB PCIe
-controller + VL805 USB hub) - the very first TRB transfer on the command
-ring fails and there is a timeout while waiting for the command completion
-event. After adding the missing cache flush everything seems to be working
-as expected.

-Subject: [PATCH 03/20] usb: xhci: Use only 32-bit accesses in
- xhci_writeq/xhci_readq
-
-There might be hardware configurations where 64-bit data accesses
-to XHCI registers are not supported properly.  This patch removes
-the readq/writeq so always two 32-bit accesses are used to read/write
-64-bit XHCI registers, similarly as it is done in Linux kernel.
-
-This patch fixes operation of the XHCI controller on RPI4 Broadcom
-BCM2711 SoC based board, where the VL805 USB XHCI controller is
-connected to the PCIe Root Complex, which is attached to the system
-through the SCB bridge.
-
-Even though the architecture is 64-bit the PCIe BAR is 32-bit and likely
-the 64-bit wide register accesses initiated by the CPU are not properly
-translated to a sequence of 32-bit PCIe accesses.
-xhci_readq(), for example, always returns same value in upper and lower
-32-bits, e.g. 0xabcd1234abcd1234 instead of 0x00000000abcd1234.

-Subject: [PATCH 09/20] pci: Add driver for Broadcom BCM2711 SoC PCIe
- controller
-
-This patch adds basic driver PCI Express controller found on Broadcom
-set-top-box SoCs, e.g. BCM2711.
-The code is based on Linux upstream driver (pcie-brcmstb.c) with MSI
-handling removed. The inbound access memory region is not currently
-parsed from dma-ranges DT property and a fixed 3GB region is used.
-
-The patch has been tested on RPI4 board, i.e. on BCM2711 SoC with VL805
-USB Host Controller.

-Subject: [PATCH 10/20] configs: Enable support for the XHCI controller on RPI4
- board (ARM 64-bit)
-
-This requires enabling BRCMSTB PCIe and XHCI_PCI drivers as well as PCI
-and USB commands. To get it working one has to call the following commands:
-"pci enum; usb start;", thus such commands have been added to the default
-"preboot" environment variable. One has to update their environment if it
-is already configured to get this feature working out of the box.

-Subject: [PATCH 11/20] arm: rpi: Add function to trigger VL805's firmware load
-
-On the Raspberry Pi 4, after a PCI reset, VL805's (a xHCI chip) firmware
-may either be loaded directly from an EEPROM or, if not present, by the
-SoC's VideCore (the SoC's co-processor). Introduce the function that
-informs VideCore that VL805 may need its firmware loaded.

-Raspberry Pi 4's co-processor controls some of the board's HW
-initialization process, but it's up to Linux to trigger it when
-relevant. Introduce a reset controller capable of interfacing with
-RPi4's co-processor that models these firmware initialization routines as
-reset lines.

-Create a non-cacheable mapping for the 0x600000000 physical memory region,
-where MMIO registers for the PCIe XHCI controller are instantiated by the
-PCIe bridge. Due to 32bit limit in the CPU virtual address space in ARM
-32bit mode, this region is mapped at 0xff800000 CPU virtual address.

- board
-
-This requires enabling BRCMSTB PCIe and XHCI_PCI drivers as well as PCI
-and USB commands. To get it working one has to call the following commands:
-"pci enum; usb start;", thus such commands have been added to the default
-"preboot" environment variable. One has to update their environment if it
-is already configured to get this feature working out of the box.
