Move code which belongs to link training (delays and resets) into

including timings is at one place.
After experiments it can be observed that link training in aardvark
hardware is very sensitive to timings and delays, so it
Hi,
we have some more improvements for PCIe aardvark controller (Armada 3720
SOC - EspressoBIN and Turris MOX).
The main improvement is that with these patches the driver can be compiled
as a module, and can be reloaded at runtime.
This series applies on top of Linus' master branch.
Marek & Pal
Providing driver's 'remove' function allows kernel to bind and unbind devices
from aardvark driver. It also allows to build aardvark driver as a module.
Compiling aardvark as a module simplifies development and debugging of
this driver as it can be reloaded at runtime without the need to reboot
to
It allows kernel modules which are not compiled into kernel image to use

For a pure VirtIO guest bringing in all the PCI quirk handling adds a
significant amount of bloat to kernel we don't need. Solve this by
adding a CONFIG symbol for the ThunderX PCI devices and allowing it to
be turned off. Saving over 300k from the uncompressed vmlinux:

Hi,
When building guest kernels for virtualisation we were bringing in a
