tpm: Add reserved memory event log

2023-02-13T08:11:20Z

Some platforms may desire to pass the event log up to Linux in the form of a reserved memory region. In particular, this is desirable for embedded systems or baseboard management controllers (BMCs) booting with U-Boot. IBM OpenBMC BMCs will be the first user. Add support for the reserved memory in the TPM core to find the region and map it.

tpm: Use managed allocation for bios event log

2023-02-13T08:11:20Z

Since the bios event log is freed in the device release function, let devres handle the deallocation. This will allow other memory allocation/mapping functions to be used for the bios event log.

tpm: of: Handle IBM,vtpm20 case when getting log parameters

2020-03-13T15:31:26Z

A vTPM 2.0 is identified by 'IBM,vtpm20' in the 'compatible' node in the device tree. Handle it in the same way as 'IBM,vtpm'. The vTPM 2.0's log is written in little endian format so that for this aspect we can rely on existing code.
