No, because this will cause the whole random data passed to the kernel to be zeroed. The real problem here is that there is no real octeon boot loader, the kernels are loaded directly from u-boot, and the u-boot version in your system is quite old and does not understand fancy yet valid ELF layouts because u-boot is designed to boot a linux kernel and nothing else. For those kind of systems, it is worth investigating whether a .umg file can be built with mkuboot, in a way similar to what the armv7 port does; this would be a better solution on the long-term, and immune to kernel layout changes.
