Table 6.2 is just examples, nothing more. It's not meant to imply that some columns force you to do things in other columns, but rather that if you have a system with a particular processor core, and want to use a certain endianess (some arm cores can be either big or little endian), and are using X ABI, you pick a target triplet such as those offered as examples. The listing is not complete, there are tons of possible target triplets just for arm. Section 6.3 is correct, the EABI supports processors of armv4t vintage and above. I believe armv4t (and possibly other arm cores) are compatible with both the EABI and the OABI. Just don't mix the two, it won't work. Pick one ABI and stick to it. This is why ABI selection (and everything else you choose) happens before creating the cross toolchain, so you don't accidentally compile your system with mixed ABIs (or other mixed things). Sorry for the confusion. If you have any recommendations on a better way to display table 6.2, please let me know.
