27 | # Enable processor type. Ordering of these is important - we want to | |
28 | # use the minimum processor type of the range we support. The logic | |
29 | # for 680x0 will only allow use of the -m68060 or -m68040 if no other | |
30 | # 680x0 type is specified - and no option is specified for 68030 or | |
31 | # 68020. The other m68k/ColdFire types always specify some type of | |
32 | # compiler cpu type flag. | |
