OK, this breaks some platforms:
   powerpc:  +   TQM850L
+(TQM850L) drivers/built-in.o: In function `bootcount_store':
+(TQM850L) build/../drivers/bootcount/bootcount.c:64: undefined reference to `flush_dca che_range'
+(TQM850L) make[1]: *** [u-boot] Error 1
+(TQM850L) make: *** [sub-make] Error 2

We'll see how many others have the same problem soon and then I'll
decide on nuking the old platforms of holding off on this change.
