Their i.MX series of application processors are in a lot of devices.

The old 6800/68000 cores live on in the S08/S09 and Coldfire lines.
I just think it's a shame the 68k architecture didn't last at least into the Pentium age.
It has no memory protection though

I didn't succeed getting a newer gcc+newlib compiled for m68k, though.
All in all, the whole ecosystem around m68k seemed to have rotted away, also m68k support was also taken out of u-boot at some point if I remember correctly.
While it certainly would be possible to fix all of this, it's just too much effort "just for fun" with no particular gain besides "because I can":
If you actually have the need for some embedded CPU, one is much better off using whatever ARM core the majority of tinkerers is currently using, that way you are less likely to experience this bitrot.
Really, it was just a problem of a maturing market. In the early days of any industry, many bespoke options can flourish. But as time passes and the market matures, power consolidates and there is no longer room for garage-companies.
I don't know for sure why Moto dropped it, but lifting from Wikipedia:
While the Motorola 68040 offered the same features as the Intel 80486 and could on a clock-for-clock basis significantly outperform the Intel chip, the 486 had the ability to be clocked significantly faster without suffering from overheating problems, especially the clock-doubled i486DX2 which ran the CPU logic at twice the external bus speed, giving such equipped IBM compatible systems a significant performance lead over their Macintosh equivalents
The only thing that isn't great is Lenovo buying Motorola. I have a feeling this will mean we wont get many android updates in the future :(
