Not sure if setting up the entire carrier board makes sense as an overlay :) Not sure if folks want to debug boot issues on a remote server for example if an overlay is needed to boot with Ethernet :) Regards, Tony

If we want to reuse a carrier board, we could factor out the carrier board dts into a dtsi file and provide the needed combinations in form of different dts files. In the bootloader world the situation is a bit different. Here we would like to have a universal phycore_am62x "board" that should be able to handle most carrier board designs using that SoM. And since u-boot is moving towards having a single source of device trees, this concept will probably no longer work anymore. So your idea with a SoM dtb sounds interesting. I wonder what ideas other SoM vendors have or how it is handled on other architectures. Regards, Wadim > > Regards, > > Tony

The phyCORE-AM62x [1] is a SoM (System on Module) featuring TI's AM62x SoC. It can be used in combination with different carrier boards. This module can come with different sizes and models for DDR, eMMC, SPI NOR Flash and various SoCs from the AM62x family. A development Kit, called phyBOARD-Lyra [2] is used as a carrier board reference design around the AM62x SoM. Supported features: * Debug UART * SPI NOR Flash * eMMC * 2x Ethernet * Micro SD card * I2C EEPROM * I2C RTC * GPIO Expander * LEDs * USB For more details, see: [1] Product page SoM: https://www.phytec.com/product/phycore-am62x [2] Product page CB: https://www.phytec.com/product/phyboard-am62x Signed-off-by: Wadim Egorov <w.egorov@phytec.de> --- arch/arm64/boot/dts/ti/Makefile | 1 + .../boot/dts/ti/k3-am62-phycore-som.dtsi | 324 ++++++++++++++++++ .../dts/ti/k3-am625-phyboard-lyra-rdk.dts | 267 +++++++++++++++ 3 files changed, 592 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-am62-phycore-som.dtsi create mode 100644 arch/arm64/boot/dts/ti/k3-am625-phyboard-lyra-rdk.dts
