/** @defgroup TPM2_IO wolfTPM2 IO HAL Callbacks
|
|
*
|
|
* This module describes the available example TPM 2.0 IO HAL Callbacks in wolfTPM
|
|
*
|
|
* wolfTPM uses a single IO callback function.
|
|
* This allows the TPM 2.0 stack to be highly portable.
|
|
* These IO Callbacks are working examples for various embedded platforms and operating systems.
|
|
*
|
|
* Here is a list of the existing TPM 2.0 IO Callbacks:
|
|
* - ST Micro STM32, through STM32 CubeMX HAL
|
|
* - Native Linux (/dev/tpm0)
|
|
* - Linux through spidev without kernel driver thanks to wolfTPM own TIS layer
|
|
* - Linux through i2c without kernel driver thanks to wolfTPM own TIS layer
|
|
* - Intel MMIO interface
|
|
* - Native Windows
|
|
* - Atmel MCUs
|
|
* - Xilinx Zynq
|
|
* - Barebox
|
|
* - QNX
|
|
* - Infineon Tri-Core
|
|
* - Microchip MPLAB X Harmony (WOLFTPM_MICROCHIP_HARMONY)
|
|
* Using custom IO Callback is always possible.
