* tpm: disociate TPMv1.x specific and generic codeMiquel Raynal2018-05-251-1001/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no changes in this commit but a new organization of the code as follow. * cmd/ directory: > move existing code from cmd/tpm.c in cmd/tpm-common.c > move specific code in cmd/tpm-v1.c > create a specific header file with generic definitions for commands only called cmd/tpm-user-utils.h * lib/ directory: > move existing code from lib/tpm.c in lib/tpm-common.c > move specific code in lib/tpm-v1.c > create a specific header file with generic definitions for the library itself called lib/tpm-utils.h * include/ directory: > move existing code from include/tpm.h in include/tpm-common.h > move specific code in include/tpm-v1.h Code designated as 'common' is compiled if TPM are used. Code designated as 'specific' is compiled only if the right specification has been selected. All files include tpm-common.h. Files in cmd/ include tpm-user-utils.h. Files in lib/ include tpm-utils.h. Depending on the specification, files may include either (not both) tpm-v1.h or tpm-v2.h.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+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>

* lib: tpm: Add command to list resourcesmario.six@gdsys.cc2017-03-261-1/+75
| | | | | | | | | | | It is sometimes convenient to know how many and/or which resources are currently loaded into a TPG, e.g. to test is a flush operation succeeded. Hence, we add a command that lists the resources of a given type currently loaded into the TPM. Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Simon Glass <sjg@chromium.org>
* cmd: tpm: Fix flush commandmario.six@gdsys.cc2017-03-261-14/+23
| | | | | | | | | | | | | Commit 7690be35de ("lib: tpm: Add command to flush resources") added a command to flush resources from a TPM. However, a previous development version was accidentially used to generate the patch, resulting in a non-functional command. This patch fixes the flush command.

* tpm: Add function to load keys via their parent's SHA1 hashmario.six@gdsys.cc2017-03-261-0/+49
| | | | | | | | | | | | | | | | | | | | If we want to load a key into a TPM, we need to know the designated parent key's handle, so that the TPM is able to insert the key at the correct place in the key hierarchy. However, if we want to load a key whose designated parent key we also previously loaded ourselves, we first need to memorize this parent key's handle (since the handles for the key are chosen at random when they are inserted into the TPM). If we are, however, unable to do so, for example if the parent key is loaded into the TPM during production, and its child key during the actual boot, we must find a different mechanism to identify the parent key. To solve this problem, we add a function that allows U-Boot to load a key into the TPM using their designated parent key's SHA1 hash, and the corresponding auth data.
