[PATCH 2/2] ARM: rockchip: rock-5a: Disable non working devices

[Sascha Hauer]

Some devices do not work in barebox because we lack phy drivers for
them. Also we need to overwrite the ranges property in pcie2x1l2.
The original upstream values do not work, likely because of some
deficiency in the PCI driver.
