Hi Simon, Thanks for pointing me to the right tree and branch. I missed that :-(.
Well I was hoping to send patches next week. I should have sent an email to the list before starting.
I will go and look at your on-going work and try to fit our STM drivers.
I will be happy to co-work on this.
Great. I'll tidy this up and send out the patches early next week.
Regards, Simon
Best regards Christophe

Hi,
This patch serie introduce TPM driver model allowing to instantiate a TPM using U_BOOT_DEVICE macro for platform_data or device tree.
As an information, there is no TCG transport protocol official specification for i2c for TPM1.2. The TPM uclass allows to support different kind of bus (LPC, I2C, SPI) keeping the TPM command duration in common.
Also, this serie introduce TPM1.2 from STMicroelectronics ST33ZP24 with I2C and SPI support. It has been ported from existing Linux drivers.
This has been tested on Beagleboard xM.
As it happens I have just been trying to clean up the TPM drivers for Kconfig and driver model.
Please see u-boot-dm branch tpm-working. I'll hurry up and try to send out some patches and update the wiki. I wonder if we can join our work somehow?
Regards, Simon
Best Regards Christophe
