I use a single linker script for all Octeon > kernels, I think. You don't need to specify the output format. We could probably make the single script you have as the standard script if it works for most bootloaders. I still don't like the way ARCH_FLAGS and LDSCRIPT_NAME needs to be specified in the conf file - this could be taken from TARGET_ABI too... JC.home | help
