char and int mix usage; also change some function's params
for data type consistent.

Xiangyang Wu f81fcf2f07 HV:MM:add 'U/UL' suffix for unsigned contant value
In the current memory module, there are many constatn value
without U/UL suffix, it is reported as MISRA C violations by
static analysis tool.

Add 'U/UL' suffix for unsigned contant value in memory module
as needed.

Note:In the most case, CPU_PAGE_SIZE(0x1000) is used as
unsigned integer contant value, so CPU_PAGE_SIZE is defined
as unsigned integer contant value, and it is safety converted
into unsigned long type according to MISRA C standard.

Junjie Mao 392542310f HV: treewide: convert suffix ULL to UL
It is already assumed that ''long'' has 8-bytes, and thus there is no need to
use ULL to indicate a 8-byte unsigned constant.

This patch changes all ULL suffixes found in the hypervisor to UL.

Mingqiang Chi 9aa9a77457 mmu:create temporary page tables for guest at run time
Before this patch, guest temporary page tables were generated by hardcode
at compile time, HV will copy this page tables to guest before guest
launch.

This patch creates temporary page tables at runtime for the range of 0~4G,
and create page tables to cover new range(511G~511G+16M) with trusty
requirement.

Mingqiang Chi e5be957945 hv:add destroy Secure world API
This patch added API destroy_secure_world, which will do:
-- clear trusty memory space
-- restore memory to SOS ept mapping
It will be called when VM is destroyed, furthermore, ept of
Secure world will be destroyed as well.

Qi Yadong 922daae198 trusty: add key_info for trusty bring-up
For trusty bring-up, key_info is needed.
Currently, bootloader did not transfer key_info to hypervisor.
So in this patch, use dummy key_info temporarily.

Derive vSeed from dSeed before trusty startup, the vSeed will
bind with UUID of each VM.

Remove key_info from sworld_control structure.

Qi Yadong b124e0da28 trusty: implement hypercall to initialize trusty
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.

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.
