| This command is based on driver model regulator's API. |
| User interface features: |
| - list - list regulator devices |
| - regulator dev <id> - show or [set] operating regulator device |
| - regulator info - print constraints info |
| - regulator status - print operating status |
| - regulator value <val] <-f> - print/[set] voltage value [uV] |
| - regulator current <val> - print/[set] current value [uA] |
| - regulator mode <id> - print/[set] operating mode id |
| - regulator enable - enable the regulator output |
| - regulator disable - disable the regulator output |
| |
| The '-f' (force) option can be used for set the value which exceeds |
| the limits, which are found in device-tree and are kept in regulator's |
| uclass platdata structure. |

| bool "Enable the 'aes' command" |
| select AES |
| help |
| This provides a means to encrypt and decrypt data using the AES |
| (Advanced Encryption Standard). This algorithm uses a symetric key |
| and is widely used as a streaming cipher. Different key lengths are |
| supported by the algorithm but this command only supports 128 bits |
| at present. |
| |
| config CMD_BLOB |
| bool "Enable the 'blob' command" |
| help |
| This is used with the Freescale secure boot mechanism. |
| |
| Freescale's SEC block has built-in Blob Protocol which provides |
| a method for protecting user-defined data across system power |
| cycles. SEC block protects data in a data structure called a Blob, |
| which provides both confidentiality and integrity protection. |
| |
| Encapsulating data as a blob |
| Each time that the Blob Protocol is used to protect data, a |
| different randomly generated key is used to encrypt the data. |
| This random key is itself encrypted using a key which is derived |
| from SoC's non-volatile secret key and a 16 bit Key identifier. |
| The resulting encrypted key along with encrypted data is called a |
| blob. The non-volatile secure key is available for use only during |
| secure boot. |
| |
| During decapsulation, the reverse process is performed to get back |
| the original data. |
| |
| Sub-commands: |
| blob enc - encapsulating data as a cryptgraphic blob |
| blob dec - decapsulating cryptgraphic blob to get the data |
| |
| Syntax: |
| |
| blob enc src dst len km |
| |
| Encapsulate and create blob of data $len bytes long |
| at address $src and store the result at address $dst. |
| $km is the 16 byte key modifier is also required for |
| generation/use as key for cryptographic operation. Key |
| modifier should be 16 byte long. |
| |
| blob dec src dst len km |
| |
| Decapsulate the blob of data at address $src and |
| store result of $len byte at addr $dst. |
| $km is the 16 byte key modifier is also required for |
| generation/use as key for cryptographic operation. Key |
| modifier should be 16 byte long. |

| help |
| This provides a a series of tests to confirm that the TPM is working |
| correctly. The tests cover initialisation, non-volatile RAM, extend, |
| global lock and checking that timing is within expectations. The |
| tests pass correctly on Infineon TPMs but may need to be adjusted |
| for other devices. |
