Huihuang Shi 7bb09f75da fix "Procedure is not pure assembler"
Misra C reqires assembly code should comply with
the rules list below:
  The assembly code's functionality should match the function's
name.If not,pls encapsulate the assembly code and give a suitable
name for describing the functionality.
V1->V2:
    1.remove the dead code
    2.update detail comment

V2->V3:
    1.replace the macro name with upper case.
    2.remove the typedef and rename the struct name
"_descriptor_table_" to "descriptor_table".

Yang, Yu-chu de53964c05 HV: Removed the unused parameters and union from gdt
In the gdt.h, it defines unions and parameters which is not used
in hypervisor. Removed them to keep the gdt definition simple.

Xiangyang Wu 5aa1ad3bfc HV:treewide:fix value outside range of underlying type
There are potential value outside range of underlying type
in some assignment expressions. This violates Rule 10.3 or
Rule 10.4 of MISRA C:2012.
BTW, all operations shall be conducted in exactly the same
arithmetic (underlying) type, otherwise, there is a
value outside range violation.

Update related assignment expressions.

V1-->V2:
	* Fix potential overflow in "pit_calibrate_tsc";
	* Move PTDEV_INVALID_PIN definition before
	  get_entry_info since this MACRO is only used by
	  debug function.

Junjie Mao c849bff850 HV: config: adapt to the generated config.h
This patch drops "#include <bsp_cfg.h>" and include the generated config.h in
CFLAGS for the configuration data.

Also make sure that all configuration data have the 'CONFIG_' prefix.

v4 -> v5:

    * No changes.

v3 -> v4:

    * Add '-include config.h' to hypervisor/bsp/uefi/efi/Makefile.
    * Update comments mentioning bsp_cfg.h.

v2 -> v3:

    * Include config.h on the command line instead of in any header or source to
      avoid including config.h multiple times.
    * Add config.h as an additional dependency for source compilation.

v1 -> v2:

    * No changes.

Huihuang Shi e591315a65 HV:treewide:C99-friendly per_cpu implementation change the per_cpu method
The current implementation of per_cpu relies on several non-c99 features,
and in additional involves arbitrary pointer arithmetic which is not MIS-
RA C friendly.

This patch introduces struct per_cpu_region which holds all the per_cpu
variables. Allocation of per_cpu data regions and access to per_cpu vari-
ables are greatly simplified, at the cost of making all per_cpu varaibl-
es accessible in files.

Junjie Mao 004d2e2696 HV: treewide: give names to unnamed structs/unions
According to the syntax defined in C99, each struct/union field must have an
identifier. This patch adds names to the previously unnamed fields for C99
compatibility.

Here is a summary of the names (marked with a pair of *stars*) added.

struct trusty_mem:

    union {
        struct {
            struct key_info key_info;
            struct trusty_startup_param startup_param;
        } *data*;
        uint8_t page[CPU_PAGE_SIZE];
    } first_page;

struct ptdev_remapping_info:

    union {
        struct ptdev_msi_info msi;
        struct ptdev_intx_info intx;
    } *ptdev_intr_info*;

union code_segment_descriptor:

    uint64_t value;
    struct {
        union {
            ...
        } low32;
        union {
            ...
        } high32;
    } *fields*;

    similar changes are made to the following structures.
    * union data_segment_descriptor,
    * union system_segment_descriptor,
    * union tss_64_descriptor, and
    * union idt_64_descriptor

struct trace_entry:

    union {
        struct {
            uint32_t a, b, c, d;
        } *fields_32*;
        struct {
            uint8_t a1, a2, a3, a4;
            uint8_t b1, b2, b3, b4;
            uint8_t c1, c2, c3, c4;
            uint8_t d1, d2, d3, d4;
        } *fields_8*;
        struct {
            uint64_t e;
            uint64_t f;
        } *fields_64*;
        char str[16];
    } *payload*;

Zide Chen 8f16faab04 HV: further cleanup of header inclusions
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
