Li, Fei1 6c8fc0a4df hv: remove vm_description_array
When we create an UOS, we didn't indicate the vmid.
Thus we can't get the vm description for the vm
description array.

Instead we use a temporary vm description to save data to
fill the vm structure when crate an UOS. It's uselesss once
UOS has created. So we don't need to maintain vm description
array here for UOS.

Junjie Mao ef3cb5ba1c treewide: remove unnecessary unnamed structs/unions
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch removes unnamed struct/union fields that can be easily
expressed in a C99-compatible way.

Here is a summary of structs/unions removed.

struct vhm_request:

    union {
        uint32_t type;                  uint32_t type;
        int32_t reserved0[16];    =>    int32_t reserved0[15];
    };

struct vhm_request_buffer:

    struct vhm_request_buffer {
        union {                         union vhm_request_buffer {
            struct vhm_request ...; =>        struct vhm_request ...;
            int8_t reserved[4096];            int8_t reserved[4096];
        }                               }

Jason Chen CJ c0d4b90415 ptdev: change remapping entry from virtual to physical based
currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.

This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.

trusty runtime memory base address, entry address and memory
size to hypervisor by trusty_boot_param structure.

In hypervisor, once HC_INITIALIZE_TRUSTY received, it will create

Qi Yadong 1fd07ba349 trusty: Simulate Secure Monitor Call(SMC) by Hypercall
For ARM, The SMC instruction is used to generate a synchronous
exception that is handled by Secure Monitor code running in EL3.
In the ARM architecture, synchronous control is transferred between
the normal Non-secure state and the Secure state through Secure
Monitor Call exceptions. SMC exceptions are generated by the SMC
instruction, and handled by the Secure Monitor.The operation of
the Secure Monitor is determined by the parameters that are passed
in through registers.

For ACRN, Hypervisor will simulate SMC by hypercall to switch vCPU
State between Normal World and Secure World.
There are 4 registers(RDI, RSI, RDX, RBX) reserved for paramters
passing between Normal World and Secure World.
