First of all, is your PPC CLIENT big or little endian? I see it is trying to load little endian which is I believe less common to have.
Anyway, let's rule out Foreman completely, can you setup DHCP and TFTP using our official documentation? Including generating tftpboot directory structure via grub2-mknetdir, make sure to use the target platform with correct endian, then scp the files onto TFTP server, setup DHCP and try then: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/chap-installation-server-setup.html#sect-network-boot-setup-ppc-grub2 The filename should be set correctly to "boot/grub2/powerpc-ieee1275/core.elf" now. Does it load from correct paths now? I have built the core.elf from RHEL 7.4, can you try that as well? http://people.redhat.com/~lzapleta/test/grub2-ppc-test.tar.xz Let's find out that first.
