[Adding Mathieu to cc]
Mathieu,
do you remember how we ended up with this?
menuconfig CORESIGHT
bool "CoreSight Tracing Support"
select ARM_AMBA
As Russell says, probably shouldn't select that symbol, most likely
we want either the individual drivers that register an amba_driver to have
a 'depends on ARM_AMBA' or alternatively replace the 'select' with 'depends
on' for the entire subsystem.
