[PATCH OLK-6.6] tpm: Add a driver for Loongson TPM device
by Hongchen Zhang 27 May '25

27 May '25

From: Qunqin Zhao <zhaoqunqin(a)loongson.cn> LoongArch inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICATLF CVE: NA -------------------------------- Loongson security engine supports random number generation, hash, symmetric encryption and asymmetric encryption. Based on these encryption functions, TPM2 have been implemented in the Loongson security engine firmware. This driver is responsible for copying data into the memory visible to the firmware and receiving data from the firmware.
