Well, it is hard to say... if you want the fastest response during the 
day (Eastern TZ), the smiths-aerospace.com address will be the one, but 
it will probably change sometime fairly soon...
(the deal is scheduled to close May 4).

The gvb.uboot at gmail is how I'm subscribed as at home, and that is 
where I work on u-boot, but the response time will be less consistent.

CC:ing the list will generally be the fastest and most reliable.

Yup, I'll add that as a desired enhancement.  The size should be 
optional like it is with "fdt addr".

Done (adding it to the ToDo list, that is).
