Can I hotplug any PCIE device (EP) directly to the RC once linux is alreday up?

Hello All,

I have started to develop PCI express support in linux and u-boot for a new platform.
I have some doubt about hotplug behaviour.

As I understand :

 PCIE link up (LTSSM) is enabled in boot loader(u-boot).
 So link up and first device detection will happen there only.

Linux kernel does not do link up and expects all these enumerations to be done by boot-loader.

My system HW structure:

There is only a root-complex in my system (which supports hotplug )
and no switch is connected downstream to this root complex's port.
I connect my device(EP) directly to the root complex.

My quextion is 
Can I connect any PCIE device (EP) directly to the RC once linux is alreday up?

Regards
Pratyush
