Implement a x86 memory barrier mb(). Furthermore, remove the previously
used mfence() function, which does the same thing.

Users experiencing random kernel crashes due to new versions of
Marvell's DDR training algorithm can solve the issue by setting DDR
speed to 1333H.
But if kernel crashes, it has to be done in U-Boot, which is impossible
without UART connection.
In order to make it easier for users, use the rescue button mechanism:
when rescue mode 9 is selected (that is when 10 LEDs are ON), U-Boot
will train DDR in 1333H mode and also update EEPROM so that subsequent
boot will use this mode.
User has to use the `eeprom` command in U-Boot or `omnia-eeprom` command
in OS to switch back to 1600K mode.

Python strings have their own notion of backslash-escaping, and that can
conflict with the intentions for strings passed to the 're' module. In
particular, I get warnings like this:
tools/patman/../patman/commit.py:9: SyntaxWarning: invalid escape sequence '\s'
re_subject_tag = re.compile('([^:\s]*):\s*(.*)')
We should use a raw string (r'...') so that all escaping is passed into
the regex module, not interpreted within the string itself.

tests on changed commands trigger execution of commands.
