[PATCH v3 0/2] tpm: Add reserved memory event log

[Eddie James]

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.

Changes since v2:
 - Improve commit message for patch 2

Changes since v1:
 - Use managed memory
