[U-Boot] [PATCH 8/8] boston: Enable ethernet PHY, reset GPIO, device probe

[Paul Burton]

Add compatible strings for the PCIe bridges & EG20T ethernet controller
such that the devices are probed during boot, without the user needing
to manually cause that to happen by running "pci enum" after boot. This
allows for use of the ethernet controller without the manual PCI
enumeration step.

We also enable the EG20T GPIO driver to provide the PHY reset GPIO, and
support for the Realtek RTL8211E PHY used on the Boston board in order
to make ethernet usable.
