Add a cli command to test the TPM device.
The command gets an arbitrary number of arguments (up to 30), which are interpreted as byte values and are feed into the TPM device after proper initialization. Then the return value and data of the TPM driver is examined. TPM commands are described in the TCG specification. For instance, the following sequence is the 'TPM Startup' command, it is processed by the TPM and a response is generated: boot > tpm 0x0 0xc1 0x0 0x0 0x0 0xc 0x0 0x0 0x0 0x99 0x0 0x1 Found TPM SLB9635 TT 1.2 by Infineon Got TPM response: 00 c4 00 00 00 0a 00 00 00 00 If the command is corrupted (fed one byte short), an error is reported: boot > tpm 0x0 0xc1 0x0 0x0 0x0 0xc 0x0 0x0 0x0 0x99 0x0 generic_lpc_tpm.c:311 unexpected TPM status 0xff000888 generic_lpc_tpm.c:516 failed sending data to TPM tpm command failed boot > Change-Id: I3f3c5bfec8b852e208c4e99ba37b0f2b875140b0 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> CC: Wolfgang Denk <wd@denx.de>
