The SoC specific wrapper IP is probably different on am18xx compared
to omaps, it might be TIPB like on omap1?
If am18xx has something simlar to omaps, there would be revision,
sysconfig and sysstatus registers typically at offsets 0x00, 0x10
and 0x14.
The wrapper IP code should be independent of the PRU code and just
provide services to the PRU. For a minimal wrapper IP driver example
that might work for am18xx see for drivers/usb/musb/musb_am335x.c.

Tony
