[Xen-devel] [PATCH v2] xen/arm: platform: fix Raspberry Pi compatible string

[Stewart Hildebrand <stewart.hildebrand@xxxxxxxxxxxxxxx>]

Both upstream [1] and downstream [2] Linux kernels use "brcm,bcm2711"
as the compatible string for Raspberry Pi 4. Add this string to our
platform compatible list.

The brcm,bcm2838 convention is abandoned. Remove it.

Rename the variables within the file to a rpi4_* prefix since the file
is meant to cover the Raspberry Pi 4 platform.
