Cool. 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.
Regards,
Tony
