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?
