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];
} }
}

According to the comments in hypervisor:
" This file includes config header file "bsp_cfg.h" and other
hypervisor used header files.
It should be included in all the source files."
this patch includes all common header files in hypervisor.h
then removes other redundant inclusions

We can use this interface for VHM to pass per-cpu power state data
to guest per its request.
For now the vcpu power state is per-vm, this could be changed if
per-cpu power state support is required in the future.

UOS_Loader will trigger boot of Trusty-OS by HC_INITIALIZE_TRUSTY.
UOS_Loader will load trusty image and alloc runtime memory for
trusty. UOS_Loader will transfer these information include
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
EPT for Secure World, save Normal World vCPU context, init
Secure World vCPU context and switch World state to Secure World.

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.
