To take care of the compressed image, the load address needs
to be passed instead of the original compressed image address.

Hello Masahisa,
Thank you for diving into this problem.
In test/py/tests/test_efi_fit.py we are testing on the sandbox with and
without compression. Why would the problem not show up in the test?
539 # Run tests
540 # - fdt OFF, initrd OFF, gzip OFF
541 launch_efi(False, False, False)
542 # - fdt ON, initrd OFF, gzip OFF
543 launch_efi(True, False, False)
544 # - fdt OFF, initrd ON, gzip OFF
545 launch_efi(False, True, False)
546
547 if is_sandbox:
548 # - fdt OFF, initrd OFF, gzip ON
549 launch_efi(False, False, True)
550 # - fdt ON, initrd OFF, gzip ON
551 launch_efi(True, False, True)
552 # - fdt OFF, initrd ON, gzip ON
553 launch_efi(False, True, True)
The test should be corrected to show you issue.
Best regards
Heinrich
