The sos_vm config under arch/x86/configs/$(CONFIG_BOARD) folder should be
customer specific configuration, leave it back to customer.
When hypervisor start building, it will check whether BOARD specific sos_vm.h
exist in configs/$(CONFIG_BOARD) folder. If exist, then include this header;
if not, then include default sos_vm config header under configs/default folder.

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.

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.
