Add board configuration for FriendlyELEC NanoPi R76S, including:
- nanopi-r76s.conf with board parameters and boot settings
- initial kernel / U-Boot patch for device tree and board bring-up
XpressReal(https://xpressreal.io/) is a family of Single Board Computers
developed in collaboration between Fyde Innovations, Radxa and Realtek.
XpressReal T3 is the first product in the family - a small form factor
high performance single board computer powered by the Realtek RTD1619B,
which runs FydeOS/openFyde and Linux!
Now we are adding the awesome Armbian Linux support for XpressReal T3!
This commit introduces some binary files that XpressReal T3 needed:
- firmware/realtek/rtd1619b
These binaries are the firmware for rtd1619b peripherals
(including the audio decoder, video decoder, etc.).
- u-boot-fw.tar.gz
This contains some co-processor firmware,
which needs to be loaded by u-boot in the early stage of boot.
- u-boot-prebuilt.tar.gz
These are hwsettings related files, used for tasks such as DDR initialization.
These files come from the rtd1619b SDK, which has already been open-sourced on our github:
- [firmware](https://github.com/XpressReal/linux-sdk/tree/main/meta-xpressreal/recipes-kernel/linux-firmware/files/rtd1619b)
- [u-boot prebuilts](https://github.com/XpressReal/linux-sdk/tree/main/meta-xpressreal/recipes-bsp/u-boot/files/prebuilt/rtd1619b)
