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

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.

Currently we reply on CONFIG_RELEASE=n to determine if a debug version should be

Linux commit edfe63ec97ed ("x86/mtrr: Fix Xorg crashes in Qemu sessions")
disables PAT feature if MTRR is not enabled. This patch does partial
emulation of MTRR to prevent this from happening: enable fixed-range
MTRRs and disable virable range MTRRs
By default IA32_PAT MSR (SDM Vol3 11.12.4, Table 11-12) doesn't include
'WC' type. If MTRR is disabled from the guests, Linux doesn't allow
writing IA32_PAT MSR so WC type can't be enabled. This creates some
performance issues for certian applications that rely on WC memory type.
Implementation summary:
- Enable MTRR feature: MTRRdefType.E=1
- Enable fixed range MTRRs: MTRRCAP.fix=1, MTRRdefType.FE=1
- For simplicity, disable variable range MTRRs: MTRRCAP.vcnt=0.
It's expected that this bit is honored by the guests and they won't
change the guest memory type through variable MTRRs.

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.

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.

microcode update from UOS is disabled.
microcode version checking is available for both SOS and UOS.
There are two TODOs of this patch:
1. This patch only update the uCode on pCPUs SOS owned. For the
pCPUs not owned by SOS, the uCode is not updated. To handle
this gap, we will have SOS own all pCPUs at boot time. So
all pCPUs could have uCode updated. This will be handled
in the patch to enable SOS own all pCPUs at boot time.
2. gva2gpa now doesn't check possible page table walk failure.
Will add the failure check in gva2gpa in different patch.

This patch is prepared for enabling secure world feature.
this api will create new eptp for secure world, whose PDPT
entries are copied form normal world,the PML4/PDPT for secure
world are separated from Normal World, PD/PT are shared in the
Secure World's EPT and Normal World's EPT.Secure world can
access Normal World's memory, but Normal World can not access
Secure World's memory
This function implemented：
-- Unmap specific memory from guest ept mapping
-- Copy PDPT from Normal world to Secure world
-- Map specific memory for Secure world
-- Unmap specific memory from SOS ept mapping

"-O2 -D_FORTIFY_SOURCE=2":
GCC C-Compiler can analyze the source code to be compiled and detect
certain insecure sections, that might create a security problem. The
compiler will replace the insecure function calls with special hardened
code that will perform extra runtime checks while the process is
executed.
"-Wformat -Wformat-security":
It warns about calls to "printf" and "scanf" functions where the format
string is not a string literal and there are no format arguments, as in
"printf (foo);". This may be a security hole if the format string came
from untrusted input and contains %n.
