我阅读了 trustzone_security_whitepaper.pdf,第 5.5 章 TrustZone API,
>To encourage the development of security solutions ARM have produced a
>standardized software API, called the TrustZone API (TZAPI), which defines
>a software interface which client applications running in the rich operating
>environment can use to interact with a security environment.
和 5.5.1 API 可用性
>"The TrustZone API can be downloaded for free from the ARM website"
我搜索了 arm 网站,但没有找到 TrustZone api 列表或手册的条目?
