How to add particular interface (I2C or SPI) to the trustzone from software in qualcomm MSM8909 platform.

sourabhdas over 7 years ago

We are using qualcomm MSM8909 platform. We want to add any of the interface (I2C or SPI) to the trustzone, so that non-secure world couldn't access it. It should only be accessed by the QSAPP apps.
