* Refresh fileenv patch for U-Boot 2025.01 * Update Tinker to U-Boot 2025.01 Needs minor patch adjustment, also fixed patch numbering. * Update ODROID-N2 to U-Boot 2025.01, move eMMC patch Move the patch for eMMC so it's applied only for N2 specifically and update it for 2025.01. * Update ODROID-C/XU to U-Boot 2025.01 No changes in patches necessary after moving the N2 patch. * Update RPi boards to U-Boot 2025.01 Changes needed in bcmstb PCIe driver due to upstream refactoring, rest only refreshed. All patches now target the same version, so we can drop one of the series. * Update VIM3 to U-Boot 2025.01 No patches here, just version bump. * Update Green to U-Boot 2025.01 Updated and refreshed patches, added a patch to disable OF_UPSTREAM which is now needed. * Update ODROID-M1 to U-Boot 2025.01 Drop patch that has been mostly merged upstream. The change is that HS400 would stay enabled but let's get back to what upstream does. * Update ODROID-M1 to U-Boot 2025.01 Drop all patches as M1S support should be now merged to U-Boot and DTS taken from upstream. * Disable DFU and mkeficapsule to fix build mkeficapsule requires gnutls to be built first but it's not among dependencies. Since we don't need the tool, we can disable it. DFU is also not used on HAOS and it implies EFI_LOADER that we already disable. Moreover, that also sets SET_DFU_ALT_INFO and leads to linker failure on some platforms where it's not implemented. * fixup! Update Green to U-Boot 2025.01 There were more changes needed in the Green config to use correct memory layout due to upstream changes, otherwise we'll have malloc failures in U-Boot proper. * Move N2 eMMC patch to more generic patches-meson To stay on the safe side, move the eMMC hack to more generic folder that's used for all targets using the meson_gx eMMC driver (i.e. C2, C4 and N2). This is still better than keeping it in hardkernel/patches which is applied only to some hardkernel boards (like it was before bump to U-Boot 20205.01).
Home Assistant Operating System
Home Assistant Operating System (formerly HassOS) is a Linux based operating system optimized to host Home Assistant and its Add-ons.
Home Assistant Operating System uses Docker as its container engine. By default it 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 and it is optimized to run Home Assistant. It targets single board compute (SBC) devices like the Raspberry Pi or ODROID but also supports x86-64 systems with UEFI.

Development
If you don't have experience with embedded systems, Buildroot or the build process for Linux distributions it is recommended to read up on these topics first (e.g. Bootlin has excellent resources).
The Home Assistant Operating System documentation can be found on the Home Assistant Developer Docs website.
