Also, BL1 I believe is signed and encrypted - hence no access. BL2 can be signed and that is how currently we are entering in NS HYP. Thanks for the explanation.By any chance, do you know if the Arndale octa (exynos 5420) also bring CPU in HYP mode the same way? Apparently the tzsw can be signed too, and hence, I was thinking of modifying a current smc call to have it set the CNTFRQ, which I believe will be in monitor mode. We had the same issue on the Arndale last year. Luckily u-boot were booting in Secure mode. It would be great to have a firmware that correctly configure the Arch timer (according the ARM ARM). But I bet the Arndale octa will have the same issue. So we will have to handle this such configuration in Xen. Can you send a new version with remarks make previously?
