This PR adds official Armbian support for two EasePi IoT gateway/NAS devices

[ifroncy01]

#Description

This PR adds official Armbian support for two EasePi IoT gateway/NAS devices:

• EasePi-A2 (RK3568) — IoT gateway with OLED display, infrared receiver, AP6255 Bluetooth, PCIe 2.5G Ethernet
• EasePi-R2 (RK3588) — 4-port 2.5G NAS with infrared receiver, AP6255 Bluetooth, SATA, HDMI IN/OUT

Changes (16 files):

• Board configs for both devices (config/boards/easepi-a2.conf, config/boards/easepi-r2.conf)
• Vendor kernel (6.1) DTS/DTSI files for both boards (patch/kernel/rk35xx-vendor-6.1/dt/)
• Mainline kernel (6.18) DTS/DTSI files for both boards (patch/kernel/archive/rockchip64-6.18/dt/)
• Legacy U-Boot patches for vendor branch (patch/u-boot/legacy/u-boot-radxa-rk35xx/)
• Mainline U-Boot (v2025.10) defconfig and DTS files (patch/u-boot/v2025.10/)
• Extension scripts for peripherals — OLED, IR, Bluetooth (extensions/easepi-a2-peripherals.sh, extensions/easepi-r2-peripherals.sh)
• Go source for OLED display (https://github.com/ifroncy01/easepi-oled-daemon)
• Vendor kernel config (config/kernel/linux-rk35xx-vendor.config)

Dependencies:

• Extends existing rk35xx and rockchip-rk3588 board families
• Mainline kernel uses rockchip64 LINUXFAMILY via rockchip64_common.inc
• U-Boot mainline overrides default radxa U-Boot via board config post_family_config__ hook
• Extracted the OLED Go source code into a dedicated repository

Documentation Summary

• short description: Add board support for EasePi-A2 (RK3568) and EasePi-R2 (RK3588)
• summary: Two new Rockchip boards for IoT gateway and NAS use cases. EasePi-A2 features OLED display, IR receiver, AP6255 Bluetooth/WiFi, and PCIe 2.5G Ethernet. EasePi-R2 features 4x 2.5G Ethernet, IR, Bluetooth, SATA, and HDMI IN/OUT. Both boards support vendor (6.1) and mainline (6.18) kernels.
• example of usage: Build with ./compile.sh BOARD=easepi-a2 BRANCH=current or ./compile.sh BOARD=easepi-r2 BRANCH=vendor

How Has This Been Tested?

• easepi-a2 vendor build — 451s, kernel 6.1.115, image generated
• easepi-a2 current build — 1022s, kernel 6.18.33, image generated
• easepi-r2 vendor build — 487s, kernel 6.1.115, image generated
• easepi-r2 current build — 914s, kernel 6.18.33, image generated
• Physical device testing (completed)

All builds: BUILD_MINIMAL=yes BUILD_DESKTOP=no KERNEL_CONFIGURE=no ARTIFACT_IGNORE_CACHE=yes

Checklist

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• My changes generate no new warnings (shellcheck passes all extension scripts)
• Any dependent changes have been merged and published in downstream modules

Summary by CodeRabbit

• New Features
  • Added EasePi‑A2 (RK3568) and EasePi‑R2 (RK3588) board support.
  • On‑board peripherals: Bluetooth, Wi‑Fi SDIO, IR receiver (NEC), OLED display, NVMe storage, PCIe Ethernet, HDMI/audio, RTC, and fan control.
  • Includes image tooling to enable services (OLED, IR, Bluetooth) and an IR diagnostic/setup helper.
  • Adds required user utilities (i2c-tools, ir-keytable, fonts) and full U-Boot + Linux kernel/device-tree support for both boards.

Not much more from my side.
Keeping extension stuff in board config file is a sane suggestion as extensions should ideally work on all boards or a whole family at least.
once the pr at linux-rockchip was accepted you can remove the needless dts in this repo from the pr.

[ifroncy01]

I will integrate the extensions into the board configuration and monitor the review status of the linux-rockchip PR.

🚫 Missing required board assets

This PR adds new board configuration(s). Required assets must already exist in github/armbian/armbian.github.io.
They are required by Armbian Imager to ensure all boards are displayed with proper images.

• Board images: board-images/<board>.png (1920x1080 px transparent)
• Vendor logos: board-vendor-logos/<vendor>-logo.png (512x512 px transparent)

Missing items

• ❌ Board image missing for easepi-a2

  • Expected: board-images/easepi-a2.png
  • Fix: add the file to armbian/armbian.github.io (folder board-images/)

• ❌ Vendor logo missing for vendor easepi (used by board easepi-a2)

  • Expected: board-vendor-logos/easepi-logo.png
  • Fix: add the file to armbian/armbian.github.io (folder board-vendor-logos/)
  • Naming rules: lowercase, dashes (e.g. kobol-logo.png, not Kobol_logo.png)

• ❌ Board image missing for easepi-r2

  • Expected: board-images/easepi-r2.png
  • Fix: add the file to armbian/armbian.github.io (folder board-images/)

• ❌ Vendor logo missing for vendor easepi (used by board easepi-r2)

  • Fix: add the file to armbian/armbian.github.io (folder board-vendor-logos/)
  • Naming rules: lowercase, dashes (e.g. kobol-logo.png, not Kobol_logo.png)

Once the missing files are added (or a PR is opened in armbian/armbian.github.io), re-run this check.

Hi @EvilOlaf @HeyMeco

The issue regarding "Missing required board assets" has already been reviewed and is ready to merge in armbian/armbian.github.io#317.

However, this PR still has a failing check related to the ShellCheck error (SC2148) on the board config files. I noticed that other board configuration files have not addressed similar issues yet. Could you please advise on how we should proceed with this error? Should we add shebangs or shellcheck directives to all board config files, or is there another preferred solution?

Thank you for your guidance!

[EvilOlaf]

It will fail until the pending PR with the assets is merged.

should we add shebangs or shellcheck directives to all board config files

No, that's slop
