[Xen-devel] [PATCH v6 05/13] make it possible to enable/disable UART drivers

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

All the UART drivers are silent options. Add one line descriptions so
that can be de/selected via menuconfig.

Add an x86 dependency to HAS_EHCI: EHCI PCI has not been used on ARM. In
fact, it depends on PCI, and moreover we have drivers for several
embedded UARTs for various ARM boards.

NS16550 remains not selectable on x86.
