How should this work if you don't define linux,sml-base and
linux,sml-size?
I have sent a patch to the linux list for using a reserved memory
region, as I have also added in the u-boot TPM layer for the event log.

Thank you for the clarification.
The kernel patch seems to need rework:
https://lore.kernel.org/all/202301040834.ysmhdmpw-...@intel.com/
Shouldn't the sandbox device-tree support these properties? This will
allow us to write a test application that the sandbox can run via
booti/bootz (depending on bitness) and bootm. This test application can
retrieve the event log and print it via Linux system calls.
Best regards
Heinrich
