 ## eMMC
 
-The ODROID XU4 uses the eMMC boot partition to boot from. Typically eMMC readers can't write to this eMMC boot partition. There are a couple of possibilities:
-
-1. **Working** e.g. the eMMC already had a working image before flashing HassOS:
-   - It will be booting to U-Boot (but no further).
-     - If you have the serial adapter, you should be able to enter `distro_bootcmd` at the uboot prompt to continue booting.
-     - If not, flash the HassOS image to an SD card and boot off that temporarily (while the eMMC is also plugged in).
-   - Once booted, login at the prompts and then enter `dd if=/dev/mmcblk0 of=/dev/mmcblk0boot0 bs=512 skip=63 seek=62 count=1440` at the linux prompt.
-   - Reboot with eMMC (don't forget to flip the boot switch to eMMC)
-2. **Not Working** e.g. a clean/wiped/corruped eMMC boot partition:
-   - You'll need to follow [Hardkernel's instructions](https://forum.odroid.com/viewtopic.php?f=53&t=6173) to get a working boot sector. Then flash HassOS and follow instructions above.
-   - Alternatively, you can try flash HassOS to both an SD and eMMC, then boot off the SD with the eMMC also plugged in, then run `dd if=/dev/mmcblk1 of=/dev/mmcblk0boot0 bs=512 skip=1 seek=0 count=16381` at the Linux prompt. Note that this is untested, but in theory should work..
+The Odroid XU4 has a hidden boot sector that is only visible on the Odroid itself (can't be written by a card reader). There are a couple possibilities:

 If you are getting permissions issues when using the dd command, try disabling RO:
 `echo 0 > /sys/block/mmcblk0boot0/force_ro`
 to re-enable after running dd:
 `echo 1 > /sys/block/mmcblk0boot0/force_ro`
-
 ## Console
 
 By default, console access is granted over the serial header and over HDMI. Certain startup messages will only appear on the serial console by default. To show the messages on the HDMI console instead, swap the order of the two consoles in the `cmdline.txt` file on the boot partition. You can also delete the SAC2 console if you don't plan on using the serial adapter.

+## Limitation 64bit
+
+The 64bit version is under development by RPi-Team. It work very nice but it could have some impacts. Actual we see that the SDcard access with ext4 are a bit slower than on 32bit.
+
+## Serial console
+

+## USB Boot
+
+USB mass storage boot is available on Raspberry Pi 4 (64-bit only), 3B, 3B+, 3A+, and 2B v1.2.
+
+For Raspberry 3B, 3A+ and 2B v1.2, to enable USB boot, add `program_usb_boot_mode=1` into `config.txt`. Note that this **permanently** alters the one-time programmable memory of the device.
+
+For Raspberry 4, make sure to update the bootloader to a stable release
+supporting USB mass storage boot (see
+[bcm2711_bootloader_config.md](https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711_bootloader_config.md#usbmassstorageboot). If no SD card is used add `sd_poll_once=on` to `dtparam` in `config.txt` (comma separated). This gets rid of `mmc0: timeout waiting for hardware interrupt` kernel errors.
+
+For more information see [RaspberryPi](https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md).
+
+### Caveats
+
+* All bootable SD cards must be removed.
+* Boot time can be significantly longer with USB. This is due to the boot process first attempting to boot from SD card, failing, and resorting to USB.
+* Many USB drives simply do not work for boot. This is likely due to minimal driver support in uboot and will not be fixed. If you can't get it to boot on one drive, try a different brand/model. SanDisk Cruzer drives seem to have a higher rate of issues.
+
+## Tweaks
+
+If you don't need bluetooth, disabled it with add `dtoverlay=pi3-disable-bt` into `config.txt`.

+The partition layout is a bit different than for regular setups. We prefer GPT, if possible. With SoCs which don't support GPT, we use the hybrid GPT. For more details about this topic, please refer to the [development](development.md) documentation.
 
 The system is designed to have as less as possible write operations on the storage media.

+The data partition is the only partition with real I/O. It will be expanded automatically at boot to the full size of the disk.
 
-This partition can be offloaded to a different drive with the utility:
+
+## 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)
 
 ```sh
 $ datactl move /dev/xxx
 ```
 
-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.
+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.

-# Home Assistant Operating System
+# Home Assistant Operating system
 
-Home Assistant Operating System (formerly HassOS) is an operating system optimized for hosting [Home Assistant](https://www.home-assistant.io) and its [Add-ons](https://www.home-assistant.io/addons/).
+Home Assistant Operating System (HassOS) is based on [buildroot](https://buildroot.org/). It's a hypervisor for Docker and supports various kind of hardware. It is also available as virtual appliance for different virtualization solutions. The whole system is optimized for hosting [Home Assistant](https://www.home-assistant.io) and its features (to be precise, the [Add-ons](https://www.home-assistant.io/addons/)). You can update the system by using OTA updates or offline updates.
 
-Home Assistant Operating System uses Docker as Container engine. It by default deploys the Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Add-Ons in separate containers. Home Assistant Operating System is **not** based on a regular Linux distribution like Ubuntu. It is built using [buildroot](https://buildroot.org/) and it is optimized for running Home Assistant, especially on single board compute (SBC) devices like the Pi, ODROID, NUC and Tinker Board (see supported hardware below).
+This is an embedded Linux which works different than a normal Linux distribution. The system is designed to run with minimal I/O and is optimized for its tasks.
 
-## Features
+If you don't have experience with embedded systems, buildroot or the build process Linux distributions, then please read up on those topics. All provided documentation here is focusing on developers with a background on embedded systems or a strong understanding of the internal workings of operating systems.
 
-- Lightweight and memory-efficient
-- Minimized I/O
-- Over The Air (OTA) updates
-- Offline updates
-- Modular using Docker
+## Focus
 
-## Supported hardware
-
-- Raspberry Pi
-- Hardkernel ODROID
-- Intel NUC
-- Asus Tinker Board
-- Virtual appliances
-
-See full list and specific models [here](./Documentation/boards/README.md)
-
-## Getting Started
-
-If you just want to use Home Assistant the official [getting started guide](https://www.home-assistant.io/getting-started/) and [installation instructions](https://www.home-assistant.io/hassio/installation/) take you through how to download Home Assistant Operating System and get it running on your machine.
-
-If you're interested in finding out more about Home Assistant Operating System and how it works read on...

-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] Add a retry limit when writing to uart console
+
+Seems that if the serial console is incorrectly
+configured in the dtb, writing to it may block indefinitely,
+thus preventing the board from booting.
+
+Let's add a retry count to unblock in such cases.

+Subject: [PATCH 02/20] usb: xhci: Add missing cache flush in the scratchpad
+ 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.

+ 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 20/20] config: Enable support for the XHCI controller on RPI4
+ 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.

-From 6643507ce30f775008e093580f0c9499dfb2c485 Mon Sep 17 00:00:00 2001
-From: Simon Hardy <simon.hardy@itdev.co.uk>
-Date: Tue, 24 Mar 2020 13:29:12 +0000
-Subject: build: Fix GRUB i386-pc build with Ubuntu gcc
-
-With recent versions of gcc on Ubuntu a very large lzma_decompress.img file is
-output. (e.g. 134479600 bytes instead of 2864.) This causes grub-mkimage to
-fail with: "error: Decompressor is too big."
-
-This seems to be caused by a section .note.gnu.property that is placed at an
-offset such that objcopy needs to pad the img file with zeros.
-
-This issue is present on:
-Ubuntu 19.10 with gcc (Ubuntu 8.3.0-26ubuntu1~19.10) 8.3.0
-Ubuntu 19.10 with gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008
-
-This issue is not present on:
-Ubuntu 19.10 with gcc (Ubuntu 7.5.0-3ubuntu1~19.10) 7.5.0
-RHEL 8.0 with gcc 8.3.1 20190507 (Red Hat 8.3.1-4)
-
-The issue can be fixed by removing the section using objcopy as shown in
-this patch.
