[Xen-devel] [PATCH v1 0/4] Renesas Stout board support (R-Car Gen2)

[Oleksandr Tyshchenko <olekstysh@xxxxxxxxx>]

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>

Hi, all.

The purpose of this patch series is to add required support to be able to run 
Xen on
Renesas Stout board [1] which uses SCIFA compatible UART as a console interface.

Actually Xen already has support for SCIF compatible UARTs which are used on 
Renesas Lager (R-Car Gen2),
Salvator-X, H3ULCB/M3ULCB (R-Car Gen3) and other development boards.
So this patch series extends existing support to be able to handle both 
interfaces.   

Tested on Stout (ARM32) and H3ULCB (ARM64) boards using current master. 
Have a plan to update Xen Wiki regarding this board.
