d3e4f69595 HV: use separated vm_config.c for each scenario
Previously we use unified vm_config.c for all scenarios and use MACROs
for each configuration items, then the initialization of vm_configs[]
becomes more complicated when definition of MACROs increase, so change
the coding style that all configurable items could be explicitly shown in
vm_configuration.c to make code more readable.

7580cddf9f HV: add scenario for logical partition
In this scenario, hypervisor will run two logical partition VMs.

Please note that the Kconfig of Hypervisor mode will be removed
gradually. In current Kconfig setting, the CONFIG_PARTITION_MODE
is still kept for now for back-compatibility.

56c193851a HV: introduce scenario Kconfig for sharing mode
Previously the vm_configs[] is defined separately for sharing mode and
partition mode, but the concept of hypervisor mode will be removed. Instead
we will introduce scenario Kconfig for hypervisor to load different vm
configurations.

SDC(Software Defined Cockpit) is a typical scenario that ACRN supported
so we introduce this scenario for previously sharing mode and move its
configurations to scenarios/sdc folder. The configuration could be used
for all boards reference.

5398c901f6 hv: remove CONFIG_PARTITION_MODE for pre-launched VM vE820 creation
Preparing for hybrid mode:

- create vE820 for pre-launched VMs and do other init code when the
  vm_config->type is PRE_LAUNCHED_VM.
- create ve820.c for each board because without wrapping by
  CONFIG_PARTITION_MODE, ve820_entry[] needs to be visible even when
  compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board
  specific function for each $(CONFIG_BOARD)/ve820.c. The reasons being:
  - don't need to define ve820_entry[32] for those boards that don't
    support pre-launched VMs.
  - more importantly, this makes it much easier to create different per-VM
    vE820 when it's needed.

649406b049 HV: refine location of platform_acpi_info header
platform_acpi_info.h should be BOARD specific so move the header file
to configs/$(CONFIG_BOARD)/ folder.

So the target acpi info file detect process is:

Compiler search for $(CONFIG_BOARD)_acpi_info.h under
hypervisor/arch/x86/$(CONFIG_BOARD)/ first (the file is supposed to be
generated by offline tool so it is not included in original source), if
found, then the file is the target acpi info file. If not and at the
same time the ENFORCE_VALIDATED_ACPI_INFO Kconfig was set, the compiler
will stop and hint user to add target acpi info file by offline tool.
If ENFORCE_VALIDATED_ACPI_INFO was unset, then compiler will continue to
search for platform_acpi_info.h as target acpi info file under
hypervisor/arch/x86/$(CONFIG_BOARD) folder (with this file we could bypass
ENFORCE_VALIDATED_ACPI_INFO check and benifit for development). If this
file is not exist, then hypervisor/arch/x86/configs/platform_acpi_info.h
will be included as final target acpi info.

The process should work for UEFI path also, with a valid platform acpi
info file, S3/S5 should work on UEFI platform.

2d469a5e5f modularization: hypervisor initilization component
hypervisor initilization component triggered by boot component,
and it calls different components initilization functions from
the highest layer.

this patch added init.c and move reorged cpu init functions into
it, keep hardware management functions in cpu.c but move other
components' init function into init.c.

the hypervisor initilization components will call:
- init_cpu_pre
- init_cpu_post
- init_bsp
- init_debug_pre
- init_debug_post
- init_guest
- init_passthru
- enter_guest_mode

the hypervisor initilization component include files:
arch/x86/init.c
include/arch/x86/init.h

this component is higest layer, so there is no reverse dependencies for it.

v2:
- separate into 2 patches, 1 for reorg, 1 for pure move.

Chen, Gang G
fc9ec5d88f hv: Derive decryption key from Seed for Trusty to decrypt attestation keybox
CSE FW uses an AEK (Attestation keybox Encryption Key) to encrypt the keybox
with AES-256-GCM algorithm before sending it to Android/Trusty. This key is
derived from the latest platform Seed by CSE FW with KDF (key derivation function)
HMAC-SHA256. After Trusty retrieves this encrypted keybox over HECI/MEI driver,
Trusty needs the same AEKkey to decrypt it. Hence, before Trusty launches,
Hypervisor derives the same AEK key from Platform Seed with the same algorithm
and the same derivation parameters, then sends this AEK along with Trusty vSeed
to Trusty world memory.

Since Platform Seed is only visible to Hypervisor and it must not be
sent to any guest VM, only Hypervisor can derive this AEK from this
Platform Seed, just like previous per-Trusty virtual Seed derivation.
Please note that Android Attestation Keybox is shared in a single hardware
platform, so all the Trusty instance/world can get the same AEK for
decryption even if there are multiple Android User OS/VMs running
on top of Hypervisor.

v1 --> v2:
	Add detailed description why we need the patch to derive an extra key

v2 --> v3:
	Convert API descriptions to Doxygen

8873859ade kconfig: optionally check if the ACPI info header is validated
Instead of using the ACPI info template in the source tree, this patch requires
a board-specific ACPI info header to be created by the user and placed under
bsp/include. Currently we'll fall back to the current platform-specific template
if such board-specific info is not available.

A configuration symbol ACPI_ENFORCE_VALIDATED_ACPI_INFO is also added to enforce
the existance of board-specific ACPI info header. Default configurations can set
this symbol if the template does not work on a board.

Updates to the getting started guide will be updated accordingly after the
offline tools to generate such header is available.

v2 -> v3:

* Rephrase the ACPI-info-related messages.

v1 -> v2:

* The generated header should depend on .config so that whenever any
  configuration changes, this header will be remade.

022ef92b62 hv: Add vrtc emulation support for ACRN partition mode
This patch adds code to support read-only RTC support for guests
run by partition mode ACRN. It supports RW for CMOS address port 0x70
and RO for CMOS data port 0x71. Reads to CMOS RAM offsets are fetched
by reading CMOS h/w directly and writes to CMOS offsets are discarded.

Add two files to do compile time assert.
One is arch specific, and put in hypervisor/arch/x86/.
The other one is common, and put in hypervisor/common/.

If the statement is not true, there will be error during compile time.
The file will not increase the size of HV binary.

f03ae8d09c HV: instr_emul: Rearrange logic of instr_emul*
Originally, there is cross-references between instr_emul.h and instr_emul_wrapper.h.
User must include both of them when calling instruction emulation functions. This
will raise up some confusion and inconvenience.

So we rearrange the logic of instruction emulation code as following:

  - External API -- defined in instr_emul.h
     * decode_instruction(struct vcpu *vcpu)
     * emulate_instruction(struct vcpu *vcpu)

  - Make all other functions as static in instr_emul.c

  - Remove instr_emul_wrapper.c/h

No functional change.

b35e330995 HV: make: check CONFIG_RELEASE=y for release build
Currently we reply on CONFIG_RELEASE=n to determine if a debug version should be
built. Though this holds due to the configuration overriding in kconfig.mk, this
only applies to make >= 3.82. For make 3.81, $(eval $(call xxx)) does not work
as expected, and thus CONFIG_RELEASE is undefined for debug builds.

Instead of checking CONFIG_RELEASE=n, this patch checks CONFIG_RELEASE=y
instead, which is guaranteed without relying on the behavior of $(eval $(call
xxx)).

116038fafc HV: make: consider header depenencies when rebuilding
With Kconfig, it would be common to rebuild the hypervisor with a few
configuration symbols changed. But for a proper rebuild, users are required to
execute ''make clean'' first, which deletes the configuration file at all.

This patch leverages the compiler to generate a target that add involved headers
as dependencies to a specific file. Any change to a header will now trigger the
rebuilding of related sources properly.

a23549aa91 HV: build: make relocation-related code configurable
The relocation feature relies on the ld option "-z noreloc-overflow" which is
only available for binutils >= 2.27, while on Ubuntu 16.04 or older the default
version of binutils is 2.26.

This patch wraps the relocation code with a configurable macro and make it
undefined by default to avoid default build failures.

NOTE: This is just a hotfix. The code dropped with undefined CONFIG_RELOC needs
to be reviewed by the original author of this feature. Checks to the binutils
version will also follow up.
