Did you tried running the drivers on board or are there any special
preparation needed?
I've BeagleBoard-xM Rev. C applied your patches and enabled the
functions the in menuconfig.
But on dmesg I see that:

[    0.685028] of_amba_device_create(): amba_device_add() failed (-19)
for /etb at 5401b000
[    0.685119] of_amba_device_create(): amba_device_add() failed (-19)
for /etm at 54010000

There are no nodes according coresight in /sys/kernel/debug/ .

Best regards,
Marcin
