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. Since the memory is mapped, not allocated, change all the event log allocation functions to managed allocations so that the memory can be either automatically freed or unmapped.
