Enable Xen hypervisor console driver. Used for Zephyr as
|
|
privileged domain (Dom0) or for Zephyr DomU in Dom0less
|
|
configuration. Dom0less configuration does not have
|
|
privileged domain. Thus, there is no console daemon and Xen
|
|
manages all domain outputs through the consoleio interface.

Set init priority for Xen HVC, should be inited before UART

console driver (HVC gets inited on PRE_KERNEL_1 stage).

Enable setting of console_io symbol hook for stdout and printk.

Log output will become available on PRE_KERNEL_1 stage. Requires

Xen, compiled with CONFIG_DEBUG flag.
