The ivshmem memory regions use the memory of the hypervisor and
they are continuous and page aligned.
this patch is used to initialize each memory region hpa.
v2: 1) if CONFIG_IVSHMEM_SHARED_MEMORY_ENABLED is not defined, the
entire code of ivshmem will not be compiled.
2) change ivshmem shared memory unit from byte to page to avoid
misconfiguration.
3) add ivshmem configuration and vm configuration references
v3: 1) change CONFIG_IVSHMEM_SHARED_MEMORY_ENABLED to CONFIG_IVSHMEM_ENABLED
2) remove the ivshmem configuration sample, offline tool provides default
ivshmem configuration.
3) refine code style.
v4: 1) make ivshmem_base 2M aligned.

ACRN Hypervisor ############### The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
