Sumit Garg
sumit.garg at linaro.org
Fri Jul 8 15:14:00 CEST 2022
Add support for 96Boards Dragonboard 845C aka Robotics RB3 development
platform. This board complies with 96Boards Open Platform Specifications.
Features:
- Qualcomm Snapdragon SDA845 SoC
- 4GiB RAM
- 64GiB UFS drive
U-boot is chain loaded by ABL in 64-bit mode as part of boot.img.
For detailed build and boot instructions, refer to
doc/board/qualcomm/sdm845.rst, board: dragonboard845c.
