2018-11-28tss: implement tlcl_save_stateJoel Kitching
When an untrusted OS is running, we would like to use the Cr50 vendor-specific VENDOR_CC_TPM_MODE command to disable TPM. Before doing this, we should save TPM state. Implement tlcl_save_state for this purpose. This needs to live in coreboot codebase since on S3 resume path, depthcharge is not reached. Implement the function in both tcg-1.2 and tcg-2.0 for completeness.

2018-11-28security/vboot: Add VB2_LIB to romstage sources without dependenciesWerner Zeh
The coming feature "measured boot" relies on VB2_LIB in romstage. In the case where there is no separate verstage, compile the library just for romstage as it will then be shared across verstage and romstage code. If there is a separate verstage, compile the library separately for verstage and romstage.

Change f849972 (security/vboot: Enable TCPA log extension) enabled support for adding TCPA log to CBMEM. However, if CBMEM is not online, this function doesn't do anything and returns early. This condition is not really a valid error condition as it depends on when the call to tcpa_log_add_table_entry is made. Since tcpa_log_add_table_entry returns -1 when cbmem is not online, tpm_extend_pcr prints an error message with prefix "ERROR:". This can confuse any scripts trying to catch errors in boot flow. This CL makes the following changes: 1. Removes the print in tpm_extend_pcr since tcpa_log_add_table_entry already prints out appropriate ERROR messages in case of failure to add log entry. 2. Since the return value of tcpa_log_add_table_entry is not used anymore, return type for tcpa_log_add_table_entry is changed to void.

2018-06-28vboot: Fix linking error with USE_OPTION_TABLE enabledPatrick Rudolph
Fix a linking problem with VBOOT and USE_OPTION_TABLE enabled. Make use of cbfs_locate_file_in_region() and always search the cmos_layout.bin in the 'COREBOOT' region. With this change applied there's no need to include the vboot_locator in SMM any more, we can't break NVRAM with different CMOS layouts, and we keep VBOOT and non VBOOT behaviour the same. Only include cmos_layout.bin and cmos.default in RO region. Add notes explaining the decisions. Tested on Intel Sandybridge, builds and boots with vboot enabled.

coreboot on skylake originally did ship with romcc bootblock and verstage running after it. However, that configuration makes boot flows very complicated. No platform in the current code base uses this combination. Make VBOOT_STARTS_IN_BOOTBLOCK depend on C_ENVIRONMENT_BOOTBLOCK.

2018-02-07security/vboot: overwrite existing spaces during factory init for tpm2Andrey Pronin
In TPM 2.0 case, if the factory initialization is interrupted after defining, say, the kernel tpm nvram space but before writing to this space, the following will happen upon reboot when the factory initialization will be re-attempted. Writing to this space will be skipped, and coreboot will finish the factory initialization with this space remained unwritten. At a later stage, when the rollback logic will attempt to check the version in the kernel space, it will fail (TPM2.0 returns an error when reading from unwritten spaces), and the system will go into recovery with no way out (since the kernel space will never be written). This change fixes that by always writing to the kernel, MRC hash and firmware spaces during factory initialization, even if the space already existed by that time. BUG=b:71884828 TEST=delete, define, but not write to the kernel space; trigger factory initialization; coreboot should fill the kernel space and continue booting.
