Unlike the normal Linux (version 4.3.0) kernel configuration, when compiling the L4Linux (same version) kernel I couldn't find an option to enable GPIO or choose a driver for the architecture I am building upon (Since I am compiling for ARM, Versatile Express Cortex-A15 board over qemu). Is there an option to enable gpio for l4linux? I even tried modifying something in the gpio driver src in l4linux and when I re-compiled, it never detected any changes.
