===========
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。Annotation

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
