At the moment the parseopt_* functions are in the fs/parseopt.c file.
Adding the parseopt_ul() for parsing u32 option value in arch/sandbox/os/ftdi.c
will lead to moving fs/parseopt.c file to common code, e.g. to lib/.
Is it ok to add 'obj-y += parseopt.o' to the lib/Makefile file?
May be you prefere to introduce special Kconfig option for parseopt.o conditional
compilation?
