OK I'll update to to use "jacinto 5 eco" specifically to avoid more
confusion.

Thanks,

[PATCH 1/3] ARM: OMAP2+: Fix SoC detection for dra62x j5-eco

[Tony Lindgren]

We can boot dra62x j5-eco using the dm814x code as the clocks and
devices are mapped in the device tree. The dra62x is also known
as jacinto 5.

We may want to add separate soc_is macros for dra62x if needed,
but this gets us to the point where we can boot dra62x with just
dts changes.

Let's also print out the unknown hawkeye register to make things
a bit easier for new SoC variants.

I'm pretty sure the "eco" in the name isn't optional. As far as I know:
jacinto 5 = dra65x ~ dm814x
jacinto 5 eco = dra62x ~ dm811x
jacinto 5 entry = dra61x/60x ~ am335x

Here ~ means equivalence modulo efuse bits.

My knowledge of TI's automotive processors is limited however, as is
public documentation, so perhaps someone from TI can ack or nak this.
