Arndale board cannont disable prefetch on

Dear All,

Actually I have sent a mail previously, but I found more info for my issue. So I am sorry that I that I send mails again,

In fact, I found that when I call " MCR p15, 1, %0, c15, c0", 3, I am trapped into unsecured mode. And I think that I have to call secure monitor(SMC) to do prefetch off safely. But I found that I cannot get the public interface to do that.

Could someone give me a hand?

Platform:

1) linaro ubuntu 13.07 2) arndale board 3) No Virtualization enabled

Best Regards

Dai Yan
