To make this comparison I did the following
to make diff's more useful:
A) Standardize the "leading zeros" in 0x prefixed figures.
B) Standardize on lack of empty lines.
C) Ignore changes in whitespace.
D) I replaced the content of the serial number
with DELETED. Similarly for kaslr-seed and
local-mac-address.
I also am using ". . ." to indicate blocks
of lines that had no changes. As the u-boot
was a serial capture, there might have
been glitches or characters dropped.
