There are some Coding Style issues like trailing white space, vertical
alignment by spaces instead of TAB as required, C++ comments etc.

Please don't do this. Instead, send a request for an update of the
mach-types.h file to the ARM custodian, please.

One blank line is enough.

I recommend not to mix the list of command definitions with other
defines.

Also, it may make sense to kepp such lists sorted, too.

In my opinion it makes little sense to define such a complex boot
command - you will lose the definition if you redefine it for
testing. Instead, define a variable containing this script, and use
"run variable" as boot command.

Did you test that these settings work?

You seem to have NOR flash, but define NO_FLSH eralier. Is this
intentional? What is the rationale behind that?
