Hmm. I looked at an old RPI3 boot-session log I have around and
it shows more text than you report. Is your serial connection
having problems? An example that is missing is the line
"U-Boot . . ." that identifies the version and build time
of U-Boot. That is rather generic material to be missing.
(I did not have a microsd card present. Such could be an
example of expected differences.)

There is the difference (yours then mine):

MMC:   mmc@7e300000: 1
vs.
MMC:   mmc@7e300000: 2

I wonder it if is some sort of clue about something.
