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@5401b000
[ 0.685119] of_amba_device_create(): amba_device_add() failed (-19)
for /etm@54010000
There are no nodes according coresight in /sys/kernel/debug/ .
Best regards,
Marcin
