[coreboot-gerrit] Change in coreboot[master]: sec/intel/txt/common.c: Only log ACM error on failure

[Angel Pons (Code Review)]

Hello build bot (Jenkins), Arthur Heymans,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/46492

to look at the new patch set (#4).

Change subject: sec/intel/txt/common.c: Only log ACM error on failure
......................................................................

sec/intel/txt/common.c: Only log ACM error on failure

The TXT_BIOSACM_ERRORCODE register is only valid if TXT_SPAD bit 62 is
set, or if CBnT is supported and bit 61 is set. Moreover, this is only
applicable to LT-SX (i.e. platforms supporting Intel TXT for Servers).

This allows TXT to work on client platforms, where these registers are
regular scratchpads and are not necessarily written to by the BIOS ACM.
