Can I use the system call provided by uboot in an assembly language program as in ppcbug?

If you are running in  the  U-Boot  environment,  then  you  can  use
standard  C programs; read about "standalone applications" - but this
is off topic here; please  read  the  docs  and  post  any  remaining
questions on the u-boot-users mailing list.

Once you started the Linux kernel, then all of  U-Boot  is  gone  and
dead and there is no way to call any U-Boot code any more - except by
resetting the board.

Best regards,

Wolfgang Denk

Of course there's no reason for it, it's just our policy.
