From e926136bb29cb9dda00f1b8960db963b6e97124b Mon Sep 17 00:00:00 2001 From: Ilias Apalodimas Date: Thu, 26 Nov 2020 23:07:22 +0200 Subject: tpm: use more than sha256 on pcr_extend The current tpm2_pcr_extend is hardcoded using SHA256. Let's make the actual command to the TPM2 configurable so we can support a wider range of algorithms and keep the current command line as-is i.e limited to SHA256 only Signed-off-by: Ilias Apalodimas Reviewed-by: Simon Glass --- include/tpm-v2.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/tpm-v2.h b/include/tpm-v2.h index 74c14fe7c51..f1826ff3858 100644 --- a/include/tpm-v2.h +++ b/include/tpm-v2.h @@ -309,11 +309,14 @@ u32 tpm2_clear(struct udevice *dev, u32 handle, const char *pw, * * @dev TPM device * @index Index of the PCR + * @algorithm Algorithm used, defined in 'enum tpm2_algorithms' * @digest Value representing the event to be recorded + * @digest_len len of the hash * * @return code of the operation */ -u32 tpm2_pcr_extend(struct udevice *dev, u32 index, const uint8_t *digest); +u32 tpm2_pcr_extend(struct udevice *dev, u32 index, u32 algorithm, + const u8 *digest, u32 digest_len); /** * Issue a TPM2_PCR_Read command. -- cgit v1.3.1
