From c8ed2a1fbe306ecbfb5c7d4156ae81c029829d95 Mon Sep 17 00:00:00 2001

Subject: [PATCH 18/19] test: tpm-tis: Get prepared to share tests between ISA
and sysbus devices
ISA and sysbus TPM-TIS devices will share their tests. Only
the main() will change (instantiation option is different).
Also the base address of the TPM-TIS device is going to be
different. on x86 it is located at 0xFED40000 while on ARM
it can be located at any location, discovered through the
device tree description.
So we put shared test functions in a new object module.
Each test needs to set tpm_tis_base_addr global variable.
Also take benefit of this move to fix "block comments using
a leading */ on a separate line" checkpatch warnings.
