Allwinner SoCs
REG Linux ships board support for Allwinner H2+/H3, H5, H6, H616/H618, and the H700 handheld tree; keep this reference page synced so contributors can find every directory.
SoCs: H2+, H3, H5, H6, H616, H618, H700
- Each SoC section lists the supported devices, from Banana Pi M2 Zero, Capcom Home Arcade, and Orange Pi One/PC/Plus boards to the Zero, 3, and M4 family.
- H700 handhelds (Anbernic RG35xx, RG40xx, RG34xx, RG28xx, RGCube) currently require you to flash and then manually edit the DTB because device detection is not yet available.
- Keep this wiki page in sync with the repo so contributors can quickly locate the proper Allwinner board tree.

Amlogic SoCs
The wiki tracks Amlogic S812 through the latest S9 Gen4 / S905X3 families, covering TV boxes, NanoPi, Khadas, Radxa, Beelink, and HardKernel boards.
SoCs: S812, S905, S905X, S905D, S905Y2, S905Y4, S905 Gen2, S905 Gen3, SM1, S922X, S922X-H, A311D, A311D2, S905D3, S912, S905X3
- S812 and the S905/S905X/S905D lines list Meson/Meson8 clones plus Khadas NanoPi, Libretech, and HardKernel TV boxes that usually require you to adjust DTBs or boot scripts for generic builds.
- The S905 Gen2 (GXM/G12A) and Gen3 (SM1 / S905X3) sections extend support to Khadas VIM2, Radxa Zero, Banana Pi M5, Khadas VIM3L, HardKernel ODROID C4, and other devices tied to vendor 5.15 kernels.
- S922X/A311D and A311D2 families cover Khadas VIM3/VIM4, Banana Pi M2S, Beelink GT-King/GT-King Pro, Radxa Zero 2, and the ODROID N2 series, while the S9 Gen4 notes Khadas VIM1S and its bespoke boot scripts.

Broadcom (Raspberry Pi) SoCs
Each Broadcom board directory (BCM2711/BCM2712/BCM2837/BCM2836/BCM2835) stages kernels, DTBs, firmware, overlays, and patches before genimage builds the FAT/Share layout for Pi and Compute Module hardware.
SoCs: BCM2711, BCM2712, BCM2837, BCM2836, BCM2835
- Board scripts copy Image, initrd, DTBs, and firmware while rewiring `boot/config.txt` + `cmdline.txt` to enable DRM/KMS helpers, fastboot, `noswap`, and other runtime defaults.
- `genimage.cfg` produces a 2 GiB REGLINUX FAT32 boot volume plus a 256 MiB userdata/SHARE slice for BCM2711/BCM2712 builds, while the older SoCs keep their legacy layouts.
- Overlays/patches load modules such as `snd_seq`, `i2c_dev`, and other audio helpers so GroovyMAME, RetroArch, and libretro cores stay compatible with the VC4/VC6 GPUs.

Mediatek MT8395
Radxa NIO 12L (Genio 1200/MT8395) board trees supply overlays, kernel configs, patches, and firmware helpers tailored to the Mediatek chipset.
SoCs: MT8395, Genio 1200
- The overlay copies MT7961/MT7668/MT8183/MT8188/MT8195 firmware under `/lib/firmware` so Wi-Fi, Bluetooth, and audio work correctly.
- Kernel configs and patches capture the Linux 6.15.0-rc2 options plus HDMI/ALSA wiring required by the MT8395 Genio 1200 board.
- `genimage.cfg` stages the kernel, initrd, modules, firmware, rescue blobs, and bootloader artifacts into a GPT image with a 2 GiB REGLINUX boot partition plus a 256 MiB SHARE userdata slice.

Qualcomm Snapdragon SoCs
Snapdragon board trees (SM8250, SM8550, and others) bundle dracut configs, firmware, overlays, and LinuxLoader/EFI artifacts for handhelds like the Retroid Pocket and AYN Odin families.
SoCs: SM8250, SM8550, QP, sd845, sm6115
- Dracut, firmware, and overlays stage Qualcomm/BRCM firmware plus fan, Bluetooth, and deterministic MAC helpers before the build copies those resources to LinuxLoader.
- Each board scripts stage Image/initrd/DTBs/modules/rescue blobs into `REGLINUX_BINARIES_DIR/boot/boot` while `genimage.cfg` produces a 2 GiB FAT32 boot and 512 MiB userdata layout.
- LinuxLoader configs contain flags such as `fbcon=rotate:3`, `DisableDisplayHW`, and device-specific DTBs; the AYANEO Pocket S entry warns that the stock Android bootloader is still missing.

Rockchip SoCs
Rockchip support spans RK3128 through RK3588 boards, where each SoC directory brings `create-boot-script`, `genimage`, overlays, DTBs, and patch fragments plus shared wiring.
SoCs: RK3128, RK3288, RK3326, RK3328, RK3399, RK3566, RK3568, RK3588
- REG Linux keeps per-SoC trees (RK3128, RK3288, RK3326, RK3328, RK3399, RK3568, RK3588) with targeted kernel versions, overlays, and DTBs that stage scripts and update blobs before `genimage` packages the image.
- Highlights cover Linux 6.10 for RK3128, 6.6 for RK3288, 6.12 for RK3326, and 6.1+ for RK3588, along with overlay helpers for temperature, ALSA cards, and Moonlight/GPU patches.
- Helpful reminders remind maintainers to run each `create-boot-script.sh`, sync `linux-defconfig`/`linux_patches`, refresh overlays, and document new board layouts.

Samsung Exynos 5422
The Samsung board tree powers the ODROID XU3/XU4 (Exynos 5422) with kernel configs, patches, overlays, and bootloader wiring.
SoCs: Exynos 5422
- Kernel configs (linux-exynos5422-defconfig) and patches tune LZ4 compression, REG Linux branding, preemption, and DRM/HID quirks for the ODROID platform.
- Board scripts stage zImage, DTBs, initrd, modules, firmware, rescue data, and U-Boot blobs before `genimage` creates FAT32 boot + userdata partitions with the proper `extlinux.conf` command line.
- Overlays install `asound.conf`, fan scripts, and patch sets for Sugarbox/SwitchRes; the integration tips remind maintainers to build U-Boot, stage artifacts, and document overlay/cmdline changes.
