image that is bootable by u-boot's 'bootm' command. My question is, since the instructions have you convert the vmlinux (elf) to a flat binary (linux.bin), how are you supposed to get the entry point to use later during the 'mkimage' step? The entry point is contained in the elf image but that information will be lost when converted to binary. I can certainly determine the entry point manually and enter it in that way. But how about an automated way such that the steps from the README can be put straight into the kernel Makefile?
Set both to zeros. You can take a look at the makefile arch/ppc/boot/images/Makefile.
Of course this is only correct for PowerPC.
Other architectures have different requirements.
BTW, if you want to make uImage linux kernel, just type 'make uImage'. uImage is an official target in Linux kernel.
Right, all of this should be taken care of in the kernel Makefile; see existing examples. Eventually look at the DENX trees which do this on PPC, ARM and MIPS.
