Merge patch series "Add support for SM3 secure hash"
Heiko Schocher <[email protected]> says:
Add SM3 secure hash, as specified by OSCCA GM/T 0004-2012 SM3 and described
at https://datatracker.ietf.org/doc/html/draft-sca-cfrg-sm3-02
TPMv2 defines hash algo sm3_256, which is currently
not supported and prevented TPMv2 chip with newer
firmware to work with U-Boot. Seen this on a ST33TPHF2XI2C
u-boot=> tpm2 init
u-boot=> tpm2 autostart
tpm2_get_pcr_info: too many pcrs: 5
Error: -90
u-boot=>
Implement sm3 hash, so we can fix this problem.
