Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.

Library support for CPU specific reset and power down sequences. This includes support for errata workarounds and the latest ARM DynamIQ CPUs.

速度型的CMOS，给友商也是差一点的 IMX309，代表机型是尼康Nikon D850、Nikon Z 7、Nikon Z 7 II等等。 尼康本来也有CMOS研发能力的，不过现在是早不如买了。 但是呢，尼康和索尼是深度合作，光学还是尼康把持的，镀膜技术很稳哦。 索尼的优势就是近水楼台先得月，优秀的CMOS总是自家alpha系列先使用。 玲玲就说 IMX451 吧，只有索尼的Sony α7 IV在使用。 尼康会跟进的，就是不知道哪个型号会用上呢？ 或许是Nikon Z6 III吧，上两代都是 IMX410，缝缝补 …

Operating Systems can configure the device through an Application Programming Interface (API). Development is simplified thanks to the API that provides control of key system functionality. Each OS features a library that allows it to interact with the SCFW.

A manufacturing tool kernel is built using the imx_v7_mfg_defconfig while the default kernel is built by using the imx_v7_defconfig and builds linux-imx-mfgtool and u-boot-mfgtool. • This is handled automatically by the MFGTool recipes listed above.

Ties in device configuration, code signing, fusing together in a single document: −CST support to generation of encryption keys and the ability to encrypt images −Manufacturing tool support to create cryptographic blobs of encryption keys. −Useful for debugging secure boot with HAB on SoCs in the Closed (Secure Configuration).

This document provides an overview on how to develop a custom i.MX solution from an i.MX BSP release. This document describes how to customize kernel changes, U-Boot, memory, and various configurations for a custom hardware solution using an i.MX SoC. MX has multiple families supported in software.

It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states. TF-A implements Arm interface standards, including:
