SPDX: Convert all of our single license tags to Linux Kernel style 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>

tpm: Add TPM command library TPM command library implements a subset of TPM commands defined in TCG Main Specification 1.2 that are useful for implementing secure boot. More TPM commands could be added out of necessity. You may exercise these commands through the 'tpm' command. However, the raw TPM commands are too primitive for writing secure boot in command interpreter scripts; so the 'tpm' command also provides helper functions to make scripting easier. For example, to define a counter in TPM non-volatile storage and initialize it to zero: $ tpm init $ tpm startup TPM_ST_CLEAR $ tpm nv_define d 0x1001 0x1 $ tpm nv_write d 0x1001 0 And then increment the counter by one: $ tpm nv_read d 0x1001 i $ setexpr.l i $i + 1 $ tpm nv_write d 0x1001 $i Signed-off-by: Che-Liang Chiou <clchiou@chromium.org>

tpm: add AUTH1 cmds for LoadKey2 and GetPubKey Extend the tpm library with support for single authorized (AUTH1) commands as specified in the TCG Main Specification 1.2. (The internally used helper functions are implemented in a way that they could also be used for double authorized commands if someone needs it.) Provide enums with the return codes from the TCG Main specification. For now only a single OIAP session is supported. OIAP authorized version of the commands TPM_LoadKey2 and TPM_GetPubKey are provided. Both features are available using the 'tpm' command, too. Authorized commands are enabled with CONFIG_TPM_AUTH_SESSIONS. (Note that this also requires CONFIG_SHA1 to be enabled.)

tpm: Add TPM command library TPM command library implements a subset of TPM commands defined in TCG Main Specification 1.2 that are useful for implementing secure boot. More TPM commands could be added out of necessity. You may exercise these commands through the 'tpm' command. However, the raw TPM commands are too primitive for writing secure boot in command interpreter scripts; so the 'tpm' command also provides helper functions to make scripting easier. For example, to define a counter in TPM non-volatile storage and initialize it to zero: $ tpm init $ tpm startup TPM_ST_CLEAR $ tpm nv_define d 0x1001 0x1 $ tpm nv_write d 0x1001 0 And then increment the counter by one: $ tpm nv_read d 0x1001 i $ setexpr.l i $i + 1 $ tpm nv_write d 0x1001 $i Signed-off-by: Che-Liang Chiou <clchiou@chromium.org>

tpm: Add function to load keys via their parent's SHA1 hash 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.
