From 2bfee22f6c60e046f6b04f2d4855fddac1f67290 Mon Sep 17 00:00:00 2001 From: Mathias Leblanc Date: Wed, 14 Nov 2012 15:31:44 +0100 Subject: [PATCH] TPM: STMicroelectronics ST33 I2C BUILD STUFF * STMicroelectronics version 1.2.0, Copyright (C) 2010 * STMicroelectronics comes with ABSOLUTELY NO WARRANTY. * This is free software, and you are welcome to redistribute it * under certain conditions. This is the driver for TPM chip from ST Microelectronics. If you have a TPM security chip from STMicroelectronics working with an I2C, in menuconfig or .config choose the tpm driver on device --> tpm and activate the protocol of your choice before compiling the kernel. The driver will be accessible from within Linux.
