You can use separate bodies. See ARM 10.1.3. E.g. in your case:

----file--- p.adb ---------
package body P is:
    procedure m (value : in thing) is separate;
    procedure n (value : in thing; temp : in natural) is separate;
end P;

----file--- p-m.adb -------
separate (P)
procedure m (value : in thing) is
begin
    ...
end m;

----file--- p-n.adb -------
separate (P)
procedure n (value : in thing; temp : in natural) is
begin
    ...
end n;
