SE HMIBSC board is based on Qcom APQ8016 SoC. One of the major difference from db410c is serial port where HMIBSC board uses UART1 as the debug console with an RS232 port, patch #2 - #4 adds corresponding driver support.
Patch #5 adds main HMIBSC board specific bits, features: - Qualcomm Snapdragon 410C SoC - APQ8016 (4xCortex A53, Adreno 306) - 2GiB RAM - 64GiB eMMC, SD slot - WiFi and Bluetooth - 2x Host, 1x Device USB port - HDMI - Discrete TPM2 chip over SPI
Features enabled in U-Boot: - RAUC updates (refer [2] for more details) - Environment protection - USB based ethernet adaptors
Feedback is very much welcome.
Changes in v2: - Rebased on top on qcom-next [1] - Added patch#1 as a fix for generic qcom board support. - Added patch#4 to enable driving GPIO pins based on pinctrl configuration. This replaces the custom GPIO configuration. - Added proper DTS file for HMIBSC board based on Linux DT pattern. - Merged board support patches into a single patch#5.
