Fix link errors caused by missing Kconfig dependencies:
- DFU_OVER_USB compiles common/dfu.c which calls g_dnl_clear_detach()
which is implemented in drivers/usb/gadget/g_dnl.c which needs USB_GADGET_DOWNLOAD. Test case:
$ printf "CONFIG_USB_GADGET_DOWNLOAD=n\nCONFIG_USB_FUNCTION_FASTBOOT=n" \ >>configs/am62px_evm_a53_defconfig $ make am62px_evm_a53_defconfig $ make CROSS_COMPILE=aarch64-linux-gnu- [...] common/dfu.c:34:(.text.run_usb_dnl_gadget+0x68): undefined reference to `g_dnl_clear_detach [...]
- With the above fixed, the same build causes:
common/spl/spl_dfu.c:29:(.text.spl_dfu_cmd+0xb0): undefined reference to `run_usb_dnl_gadget'
This is because SPL_DFU compiles common/spl/spl_dfu.c which calls run_usb_dnl_gadget() which is implemented in common/dfu.c which needs DFU_OVER_USB.
Therefore add these dependencies to Kconfig.
