Hi Eddie,

This has a few failures on the CI [0].
Please have a look and let me know if you can't understand the failures


Hi, I think I have fixed the sandbox ones for v9. I'm unsure about the EFI selftest one in qemu targets...


Thanks,

Eddie

This series adds support for measuring the boot images more generically
than the existing EFI support. Several EFI functions have been moved to
the TPM layer. The series includes optional measurement from the bootm
command.
A new test case has been added for the bootm measurement to test the new
path, and the sandbox TPM2 driver has been updated to support this use
case.
This series is based on Ilias' auto-startup series and Simon's additions.

Changes since v7:
  - Change name of tcg2_init_log and add more documentation
  - Add a check, when parsing the event log header, to ensure that the
    previous stage bootloader used all the active PCRs.
  - Change name of tcg2_log_find_end
  - Fix the greater than or equal to check to exit the log parsing
  - Make sure log_position is 0 if there is any error discovering the log
  - Return errors parsing the log if the data is corrupt so that we don't
    end up with half a log

Changes since v6:
  - Added comment for bootm_measure
  - Fixed line length in bootm_measure
  - Added Linaro copyright for all the EFI moved code
  - Changed tcg2_init_log (and by extension, tcg2_measurement_init) to
    copy any discovered event log to the user's log if passed in.

Changes since v5:
  - Re-ordered the patches to put the sandbox TPM driver patch second
  - Remove unused platform_get_eventlog in efi_tcg2.c
  - First look for tpm_event_log_* properties instead of linux,sml-*
  - Fix efi_tcg2.c compilation
  - Select SHA* configs
  - Remove the !SANDBOX dependency for EFI TCG2
  - Only compile in the measurement u-boot command when CONFIG_MEASURED_BOOT
    is enabled

Changes since v4:
  - Remove tcg2_measure_event function and check for NULL data in
    tcg2_measure_data
  - Use tpm_auto_startup
  - Fix efi_tcg2.c compilation for removing tcg2_pcr_read function
  - Change PCR indexes for initrd and dtb
  - Drop u8 casting in measurement test
  - Use bullets in documentation

Changes since v3:
  - Reordered headers
  - Refactored more of EFI code into common code
     Removed digest_info structure and instead used the common alg_to_mask
       and alg_to_len
     Improved event log parsing in common code to get it equivalent to EFI
       Common code now extends PCR if previous bootloader stage couldn't
       No need to allocate memory in the common code, so EFI copies the
       discovered buffer like it did before
     Rename efi measure_event function

Changes since v2:
  - Add documentation.
  - Changed reserved memory address to the top of the RAM for sandbox dts.
  - Add measure state to booti and bootz.
  - Skip measurement for EFI images that should be measured

Changes since v1:
  - Refactor TPM layer functions to allow EFI system to use them, and
    remove duplicate EFI functions.
  - Add test case
  - Drop #ifdefs for bootm
  - Add devicetree measurement config option
  - Update sandbox TPM driver
