[Xen-devel] [PATCH v4 05/10] 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.

The next patch will take care of fixing arch dependencies.

Changes in v4:
- improve commit message
- remove prompt for HAS_EHCI

Changes in v3:
- NS16550 prompt if ARM

Changes in v2:
- make HAS_EHCI depend on x86
