Before checking any given target, make has an additional phase to check if any
included makefile should be updated. This patch enforces running oldconfig in
this phase to update .config and config.mk (if necessary). This ensures that
make gets the correct configurations when executing the given target.

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.

This patch implements the following targets as an includable .mk to the make
system of the hypervisor.
make defconfig PLATFORM=xx:
force (re)generating the default configuration for xx
make oldconfig PLATFORM=xx:
generate a configuration for platform xx based on .config if available
make minimalconfig
save a minimized .config to defconfig
The default target (make all) will generate a default configuration if no
.config is available.
The values defined in .config are available in the toplevel Makefile after
kconfig/kconfig.mk is included.
v4 -> v5:
* Add minimalconfig for generating default configs.
v3 -> v4:
* No changes.
v2 -> v3:
* "make defconfig" now correctly overwrite an existing .config.
* Add short descriptions on where each target is supposed to be used.
v1 -> v2:
* Add proper dependency checks in the Makefile of hypervisor.

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 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.

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

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
