At least the at91rm9200dk and cmc_pu2 are supposed to boot  from  NOR
flash  -  they  did in earlier versions of U=-Boot, but probably have
not undergone much testing lately. I have only  the  AT91RM9200DK  in
immediate  access at the moment - this one boots 1.2.0-g14da5f76 just
fine.

If recent versions should not work any  more  it  would  be  nice  if
someone  with  suitable hardware could run a git bisect to locate the
culprit. Thanks in advance.

Best regards,

Wolfgang Denk

If a packet hits a pocket on a socket on a port,
And the bus is interrupted as a very last resort,
And the address of the memory makes your floppy disk abort,
Then the socket packet pocket has an error to report! - Ken Burchill?
