xenvm: drivers: serial: Implement serial interface to Xen PV console This commit adds minimal support of Xen hypervisor console via UART-like driver. Implementation allows to use poll_in/poll_out char interface for uart_console.c driver directly to HV console instead of using Xen virtual PL011 UART. Future implementation will support interrupt driven interface on Xen event channels, currently it is under development. Also this commit introduces early console_io Xen interface, which allows to receive printk/stdout messages quickly after start, but requires Xen, built with CONFIG_DEBUG option.

xen: implement Xen domain control interface Add Xen domctl API implementation for Zephyr as control domain. Previously Zephyr OS was used as unprivileged Xen domain (Domain-U), but it also can be used as lightweight Xen control domain (Domain-0). To implement such fuctionality additional Xen interfaces are needed. One of them is Xen domain controls (domctls) - it allows to create, configure and manage Xen domains. Also, used it as a possibility to update files copyright and licenses identifiers in touched files. Signed-off-by: Dmytro Firsov <dmytro_firsov@epam.com>

xenvm: drivers: xen: add Xen grant table driver This commit introduces driver for granting access for own grant table and for mapping/unmapping foreign gref. Grant tables are used for data exchange between Xen domains via shared memory page(s) (e.g. for sharing ring buffer with driver data) This functionality is widely used and needed for implementing PV backend/frontend drivers.

xen: add helper functions for Xen domain memory management Add wrapper functions for Xen memory managment hypercall. They can be used for unprivilaged Zephyr guest initialization and for domain management, when Zephyr is used as Xen Domain 0. Signed-off-by: Dmytro Firsov <dmytro_firsov@epam.com>
