Hi,
ARM and X86 basically use the same 8250 driver. Let's consolidate them and
introduce an architecture independent UART driver structure.
Tested on a Jetson TK1, TX1 and X86 Qemu VM.
Untested: MMIO-based access on x86.
This shrinks hypervisor code by 46 lines. (at least something... and avoids
redundancies

Ralf Ramsauer (7):
core: arm: uart: remove superfluous includes
core: arm: rename struct uart_chip's write to write_character
core: add reg_{in,out,dist} to struct uart_chip
core: introduce common uart structure
core: make 8250 uart driver available to all architectures
core: establish a common uart interface
core: arm: uart: remove include guards
