A warning can (and will) be generated for options that are set by a BSP and don't end up in a final .config, but that's only if you've placed them in a .cfg file and fed them through the config auditing steps of the linux-yocto build (this is automatic). dependencies won't be set automatically, it's the opposite, you must ensure they are set or a particular Kconfig value must select them. > It worked after I added following 3 options stated as dependent options > in a Kernel configuration database that I saw: > > CONFIG_ISA > CONFIG_EISA > CONFIG_NET_PCI > > I am still iterating to check if all three of the above are really needed or > or if just the CONFIG_NET_PCI option is needed. > > I had enabled the option using a .cfg file.
