Subject: Re: [PATCH v2 0/5] Initial support of Trusted Foundations on Tegra30

Kexec works for me on T30 with the following kernel config options on top of the
tegra_defconfig:

CONFIG_SMP=n
CONFIG_CPU_IDLE=n
CONFIG_TEGRA_IOMMU_SMMU=n

CPU stopping isn't working correctly with the trusted foundations and it's not
obvious what is wrong. I hope we'll fix it at some point.
