Hello, I am working on a custom board that I have defined out of tree with CONFIG_ARCH_BOARD_CUSTOM.
I started development with NuttX v9.0.0, and as I saw there was a requirement for a directory named "drivers" inside my custom board, but I left this dir empty with a dummy Kconfig file. Later on I updated to NuttX v9.1.0. And then I needed to also add some custom board specific drivers. But I realized that the $(BOARD_DIR)/drivers directory is no longer used. There is no information on this in release notes. Furthermore the link nuttx/drivers/platform always points to nuttx/drivers/dummy. In NuttX 9.1.0, how can I add my own board-specific drivers? What is the correct structure to have nuttx/drivers/platform to point to my drivers directory?
