204 | help | |
205 | If you configure the kernel to include many drivers built-in instead | |
206 | as modules, the kernel executable may become too big, so that the | |
207 | linker will not be able to resolve some long branches and fails to link | |
208 | your vmlinux kernel. In that case enabling this option will help you | |
209 | to overcome this limit by using the -mlong-calls compiler option. | |

212 | a kernel which includes all necessary drivers built-in and which can | |
213 | be used for TFTP booting without the need to have an initrd ramdisk. | |
