Thanks Tom. I've been looking at this some too, and while the commands are removed from the build I've been playing with (hawkboard), they seem to not be removed completely from omap3_beagle. This is confusing as both use -ffunction-sections, -fdata-sections, and --gc-sections. I noticed the hawkboard has it's own linker script for SPL builds, and I'm wondering if this doesn't account for the difference. spl/u-boot-spl.lds uses wild cards for data where u-boot-spl-hawk.lds explicitly names the data sections to link. I'm far from an expert on linker scripts, so I can't test this theory without fear of messing up something.
