Bug Description

[Impact]
Enable TPM CRB driver on ARM64 for Qualcomm Centriq 2400. Where, control area buffer address is greater than 32-bit.

[Test]
Currently only built for X64 & ACPI. After building for arm64 validate using tcg testsuite.

[Fix]
This is upstream:
- tpm_crb: remove a cruft constant
- tpm/tpm_crb: Enable TPM CRB interface for ARM64
- tpm_crb: check for bad response size
- tpm_crb: encapsulate crb_wait_for_reg_32
- tpm_crb: map locality registers
- tpm crb: Work around BIOS's that report the wrong ACPI region size
- tpm, tpm_crb: Handle 64-bit resource in crb_check_resource()

[Regression Potential]
All patches are isolated to the TPM driver.

Jeff,

A test kernel with patches to enable tcm-crb is available for testing
in https://launchpad.net/~centriq-team/+archive/ubuntu/lp1716033-tpm/
This kernel has patches to enable tcm-crb for ARM64.

Could you please test this kernel and post test results here? Once we
get positive test results I can submit the patches for SRU.

Thanks
Manoj Iyer
