Just have two static tables. Probe the flash for the bigger size
and check what the probe found. You can find an example in
ftp://gnudd.com/pub/tattile/kernel/patch-2.4.19-rmk4-ds2-mck1-tat2 .

This is the important code from that patch (this is 4M or 8M):

+               parts = tat_partitions4;
+               nb_parts = NB_OF(tat_partitions4);
+               if (mymtd->size == 8<<20) {
+                       parts = tat_partitions8;
+                       nb_parts = NB_OF(tat_partitions8);
+               }
