This changes how tpm_register_put() debug messages are displayed to show only the bytes that are sent instead of some uninitialized bytes as well. BUG=none BRANCH=none TEST=make buildall; run on Cr50 hardware On the console, run chan -1 to enable displaying the debug output. Before this CL, you'd see messages like this: tpm_register_put(0x024, 21 180) tpm_register_put(0x024, 1 17f) tpm_register_put(0x018, 1 120) tpm_register_put(0x018, 1 140) Afterwards, you'd see accurate messages: tpm_register_put(0x024, 21, 80 01 00 00 ...) tpm_register_put(0x024, 1, 01) tpm_register_put(0x018, 1, 20) tpm_register_put(0x018, 1, 40) Change-Id: Iad798804a4b6060e9bfafad50c90138eb1144c8f Signed-off-by: Bill Richardson <wfrichar@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/382664 Reviewed-by: Vadim Bendebury <vbendeb@chromium.org>
