Several DesignWare-based drivers (dra7xx, exynos, imx6, keystone, qcom, and
spear13xx) had similar loops waiting for the link to come up.

Add a generic dw_pcie_wait_for_link() for use by all these drivers so the
waiting is done consistently, e.g., always using usleep_range() rather than
mdelay() and using similar timeouts and retry counts.

Note that this changes the Keystone link training/wait for link strategy,
so we initiate link training, then wait longer for the link to come up
before re-initiating link training.

The cavium,pci-thunder-ecam devices are exactly ECAM-based PCI root
complexes.  These root complexes (loosely referred to as ECAM units in the
hardware manuals) are used to access the Thunder on-chip devices.  They
are special in that all the BARs on devices behind these root complexes are
at fixed addresses.

Add a driver for these devices that synthesizes Enhanced Allocation (EA)
capability entries for each BAR.

Since this EA synthesis is needed for exactly two chip models, we can hard-
code some assumptions about the device topology and the layout of the
config space of specific DEVFNs in the driver.

Use usleep_range() instead of udelay() while waiting for a VPD access to
complete.  This is not a performance path, so no need to hog the CPU.

Rationale for usleep_range() parameters:

  We clear PCI_VPD_ADDR_F for a read (or set it for a write), then wait for
  the device to change it.  For a device that updates PCI_VPD_ADDR between
  our config write and subsequent config read, we won't sleep at all and
  can get the device's maximum rate.

  Sleeping a minimum of 10 usec per 4-byte access limits throughput to
  about 400Kbytes/second.  VPD is small (32K bytes at most), and most
  devices use only a fraction of that.

  We back off exponentially up to 1024 usec per iteration.  If we reach
  1024, we've already waited up to 1008 usec (16 + 32 + ... + 512), so if
  we miss an update and wait an extra 1024 usec, we can still get about
  1/2 of the device's maximum rate.

The aer_inject driver is very quiet.  In most cases, it merely returns an
error code to user-space, leaving the user with little clue about the
actual reason for the failure.

So, log error messages for 4 of the most frequent causes of failure:
* Can't find the root port of the specified device.
* Device doesn't support AER.
* Root port doesn't support AER.
* AER device not found.

This gives the user a chance to understand why aer-inject failed.

EPERM means "Operation not permitted", which doesn't reflect the lack of
support for AER.  EPROTONOSUPPORT (Protocol not supported) is a better
choice of error code if the device or its root port lack support for AER.

Likewise, EINVAL means "Invalid argument", which is not suitable for cases
where the AER error device is missing or unusable.  ENODEV and
EPROTONOSUPPORT, respectively, fit better.

The configuration space mapping on Tegra is somewhat special, and in order
to avoid wasting virtual address space the configuration space for each bus
needs to be stitched together from several blocks which form a single
continuous virtual address range for accessors.

Currently the configuration space is mapped upon the first access to one of
its registers.  However, the mapping operation may sleep under certain
circumstances, so doing it from the configuration space accessors (they are
protected by a spin lock) will trigger a warning.

To avoid the warning, use the ->add_bus() callback to perform the mapping
at enumeration time when the operation is allowed to sleep.  Also add an
implementation of ->remove_bus() that undoes the mapping established by the
->add_bus() callback.  While it isn't currently possible to unload the
module, there is work underway to remedy this, and this code will come in
handy when that happens.
