TPM2.0 needs more NvMem space and currently the whole block is contiguous in memory with 2 partitions. This CL removes the requirement that the partitions are in contiguous which allows for 1 partition to placed at top of RW_A and the other at RW_B. This CL does not change the size of each partition as that will be done in a subsequent CL. BRANCH=none BUG=chrome-os-partner:56798 TEST=manual Tested with the unit test 'make runtests TEST_LIST_HOST=nvmem' and verified that all tests pass. Tested on Kevin, erased the existing NvMem area and verified that TPM was still manufactured and executed the command: trunks_client --own Erased parition 0 and 1 in the new locations and repeated the tests.
