This is here to configure the UPR[UP] (UPR is present flag) to 1, even incase we didnt set it above when we do: SET_H_SYS_UPR (or1k_upr); The call to SET_H_SYS_UPR() sets all of the flags in the UPR as sent infrom the user arguments. If they didn't set UPR[UP] we make sure it getsset.
Oh ok for some reason I though that CHECK_SPR_FIELD was throwing an error when a check failed, but actually it just prints a warning. That's why I thought that the UP bit would necessarily already be set at this point.
Sorry about that. Simon
