[U-Boot] L2 Cache lockdown on ARM Cortex A9, Omap4 - Panda

Hi guys,

I am looking for a way to do a partial cache L2 lockdown using U-boot on Panda. Is it possible? I've tried done it many different ways (..) but this looks the most promising. According to the TRM of A9 and PLC310 CC, it is needed to set some bits in Auxiliary Control Registrer, and this should be done before the kernel boots up?

Is my approach kind of right?

Cheers, D.
