charset="utf-8" From: Jared Rossi We are already using the libc from SLOF for the s390-netboot.img, and this libc implementation is way more complete and accurate than the simple implementation that we currently use for the s390-ccw.img binary. Since we are now always assuming that the SLOF submodule is available when building the s390-ccw bios (see commit bf6903f6944f), we can drop the simple implementation and use the SLOF libc for the s390-ccw.img binary, too. Additionally replace sclp_print calls with puts/printf now that it is avali= able.
