drivers: pci: imx: add imx_pcie_remove function

2017-05-31T08:09:03+00:00

There is no dedicated reset signal wired up for the MX6QDL thus if the
bootloader enables the link we need some special handling to get the core
back into a state where it is safe to touch it for configuration.

While there has been some special handling in the Linux kernel to do this,
it was removed in 4.11 thus we need to do it properly in the bootloader
and therefore without this if you enable PCI in the bootloader you will hang
while booting the 4.11 kernel.

This puts the PCIe controller back into a safe state for the kernel driver
before launching the kernel.

Put pci_get_hose_head() prototype in header so it is available to
external users, allowing them to find and iterate over all pci
controllers.

pci: Add functions to update PCI configuration registers

2016-03-17T02:27:23+00:00

It is common to read a config register value, clear and set some bits, then
write back the updated value. Add functions to do this in one step, for
convenience.
