TMS570 dual-lockstep automotive safety controllers are hardwired to be big-endian. Their close cousins the RM57 line look like nearly identical parts that are little-endian. I believe, but cannot prove, that the only difference in silicon is a factory one-time-programmable setting (fuse). "Why would anyone want to build a BE machine?" In this case, they are trying to gain market-share from big-endian POWER microcontrollers.
