syslinux is for x86 only, and "localboot" means to exit syslinux to
let the bios (legacy or uefi) boot according to its next boot option.
u-boot has a boot variant named sysboot and that uses a confguration
file that looks like a syslinux configuration file, but there is no
actual relationship between them. u-boot also has boot variants for
other ways of booting with the kernel+initrd+dtb settings provided in
different ways.
