+===========
+固件TPM驱动
+===========
+
+本文档描述了固件可信平台模块（fTPM）设备驱动。
+
+介绍
+====
+
+该驱动程序是用于ARM的TrustZone环境中实现的固件的适配器。该驱动
+程序允许程序以与硬件TPM相同的方式与TPM进行交互。
+
+设计
+====
+
+该驱动程序充当一个薄层，传递命令到固件实现的TPM并接收其响应。驱动
+程序本身并不包含太多逻辑，更像是固件与内核/用户空间之间的一个管道。
+
+固件本身基于以下论文：
+https://www.microsoft.com/en-us/research/wp-content/uploads/2017/06/ftpm1.pdf
+
+当驱动程序被加载时，它会向用户空间暴露 ``/dev/tpmX`` 字符设备，允许
+用户空间通过该设备与固件TPM进行通信。
