Thank you for fixing the kexec source :) Are you seeing the occasional crc errors when uncompressing the new kernel on your v7? I'm seeing those maybe 1 out of 10 times on omap3430 boards unless if I do an extra (and wrong) flush_cache_all after local_flush_tlb_all at the end of setup_mm_for_reboot. If you're not seeing the crc errors, do you have L2 cache on? Also, what's the Cortex version on your v7? It's rev r2p3 on omap3430.
