2022-05-23tpm: add support for TPMv2.x I2C chipsEddie James1-0/+1
Add the tpm2_tis_i2c driver that should support any TPMv2 compliant I2C chips, such as the NPCT75X chip.

2021-11-10tpm2: Add a TPMv2 MMIO TIS driverIlias Apalodimas1-0/+1
Add support for devices that expose a TPMv2 though MMIO. Apart from those devices, we can use the driver in our QEMU setups and test TPM related code which is difficult to achieve using the sandbox driver (e.g test the EFI TCG2 protocol). It's worth noting that a previous patch added TPMv2 TIS core functions, which the current driver is consuming.

2021-08-01sandbox: tpm: Split out common nvdata codeSimon Glass1-2/+2
We want to support nvdata in TPM2 as well. To avoid code duplicating the associated code, move it into a common file. Drop the special-case logic for the kernel space. This can be handled by the higher-level code now, i.e. in vboot itself. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-3/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2015-08-31dm: tpm: Add a uclass for Trusted Platform ModulesSimon Glass1-0/+2
Add a new uclass for TPMs which uses almost the same TIS (TPM Interface Specification) as is currently implemented. Since init() is handled by the normal driver model probe() method, we don't need to implement that. Also rename the transfer method to xfer() which is a less clumbsy name. Once all drivers and users are converted to driver model we can remove the old code.

2015-08-31tpm: Move the I2C TPM code into one fileSimon Glass1-2/+0
The current Infineon I2C TPM driver is written in two parts, intended to support use with other I2C devices. However we don't have any users and the Atmel I2C TPM device does not use this file. We should simplify this and remove the unused abstration. As a first step, move the code into one file. Also the name tpm_private.h suggests that the header file is generic to all TPMs but it is not. Rename it indicate that it relates only to this driver Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>
2014-01-08sandbox: tpm: Add TPM emulationSimon Glass1-0/+1
Add a simple TPM emulator for sandbox. It only supports a small subset of TPM operations. However, these are enough to perform common tasks. Note this is an initial commit to get this working, but it could use cleaning up (for example constants instead of open-coded values).

2013-06-03tpm: Reorganize the I2C TPM driverTom Wai-Hong Tam1-3/+4
This patch does a similar code reogranzation from http://patchwork.ozlabs.org/patch/132179/ which is based on an old version of code (fdt support and bus selection still not in). It merges this tidy-up on top of the recent code. It does not make any logical change. tpm.c implements the interface defined in tpm.h based on underlying LPC or I2C TPM driver. tpm.c and the underlying driver communicate throught tpm_private.h. Note: Merging the LPC driver with tpm.c is left to future patches.

2011-12-07Introduce generic TPM support in u-bootVadim Bendebury1-0/+43
TPM (Trusted Platform Module) is an integrated circuit and software platform that provides computer manufacturers with the core components of a subsystem used to assure authenticity, integrity and confidentiality. This driver supports version 1.2 of the TCG (Trusted Computing Group) specifications. The TCG specification defines several so called localities in a TPM chip, to be controlled by different software layers. When used on a typical x86 platform during the firmware phase, only locality 0 can be accessed by the CPU, so this driver even while supporting the locality concept presumes that only locality zero is used. This implementation is loosely based on the article "Writing a TPM Device Driver" published on http://ptgmedia.pearsoncmg.com Compiling this driver with DEBUG defined will generate trace of all accesses to TMP registers. This driver has been tested and is being used in three different functional ChromeOS machines (Pinetrail and Sandy Bridge Intel chipsets) all using the same Infineon SLB 9635 TT 1.2 device. A u-boot cli command allowing access to the TPM was also implemented and is being submitted as a second patch.
