[PATCH v2 0/3] qcom: Add support for Thundercomm RUBIK Pi 3

[Hongyang Zhao]

Add initial U-Boot support for the Thundercomm RUBIK Pi 3,
a QCS6490-based development board with 8 GiB LPDDR4x memory.

The series adds the board-specific U-Boot device tree override,
a defconfig, and board documentation.

Changes in v2:
- Rename the defconfig to qcom_qcs6490_rubikpi3_defconfig.
- Drop the MAINTAINERS update; the existing qcom matching covers it.
- Add instructions for entering EDL mode on RUBIK Pi 3.
- Update the documentation for the renamed defconfig.
- Link to v1: https://lore.kernel.org/r/20260617-qcs6490-rubikpi3-v1-0-495f618a1e4c@thundersoft.com
