Zide Chen 1bc5c7ac5b hv/acrn-config/efi-stuf: assign hvlog and ramoops buffer address < 256MB
If HV relocation is enabled, either ACRN efi-stub or GRUB relocates
hypervisor image above HPA 256MB, thus we put hvlog and ramoops buffer
under 256MB to avoid conflict with hypervisor owned address.

This patch hardcodes these addresses:

0xa00000 - 0xdfffff: 4MiB for ramoops buffer
0xe00000 - 0xffffff: 2MiB for hvlog buffer

However, user can customize them to other addresses as long as it's under
256MB, available in host e820, and SOS bootarg "nokaslr" is not specified.

If HV relocation is disabled, need to make sure that these buffer
addresses are not between HV_RAM_START and HV_RAM_START + HV_RAM_SIZE.

Zide Chen be4797a10c efi-stub: don't relocate hypervisor to address lower than 256MB
With this patch, we relocate hypervisor image to HPA 256MB and above,
thus the hardcoded hvlog and ramoops buffer for SOS can safely reside at
addresses under HPA 256MB, given that 1:1 mapping between SOS GPA and HPA.

Yin Fengwei c9e3d36ef1 efi-stub: fix wrong bootloader name issue
UEFI pass option as unicode string to efi-stub. That string has
no end charactor ('\0'). Insteadly, the option has string size
and we should use the string size to decide the end of the option
string.

Zide Chen 67cb1029d9 hv: update the hypervisor 64-bit entry address for efi-stub
- remove .data and .text directives. We want to place all the boot data and
  text in the .entry section since the boot code is different from others
  in terms of relocation fixup. With this change, the page tables are in
  entry section now and it's aligned at 4KB.

- regardless CONFIG_MULTIBOOT2 is set or not, the 64-bit entry offset is
  fixed at 0x1200:

  0x00 -- 0x10: Multiboot1 header
  0x10 -- 0x88: Multiboot2 header if CONFIG_MULTIBOOT2 is set
  0x1000: start of entry section: cpu_primary_start_32
  0x1200: cpu_primary_start_64 (thanks to the '.org 0x200' directive)
          GDT tables
	  initial page tables
	  etc.

Conghui Chen 557e7f19f7 Makefile: add gcc flags to prevent some optimization
Add the below flags, they are needed in -O2:

-fno-delete-null-pointer-checks:
    * tells the compiler NOT to assume that null pointer deference does
    not exist.

    * Without this flag, below case cannot be detected:
    a pointer might point to nullsometime during run-time and if there
    is no validation for that pointer, it will cause the program to crash.
    Since we don’t receive an error message saying that a pointer is
    pointing to null, we will have a hard time trying to find the problem.

-fwrapv:
    * tells the compiler that signed overflow always wraps.

    * Without this flag, x + 10 > x will always be true for signed x.
     With the flag, x + 10 > x is not always be true, as the overflow is
     defined for x, and it could wrap.

Geoffroy Van Cutsem 51a43dab79 hv: add Kconfig parameter to define the Service VM EFI bootloader
Add a Kconfig parameter called UEFI_OS_LOADER_NAME to hold the Service VM EFI
bootloader to be run by the ACRN hypervisor. A new string manipulation function
to convert from (char *) to (CHAR16 *) has been added to facilitate the
implementation.

The default value is set to systemd-boot (bootloaderx64.efi)

Li Fei1 af886fee8c efi-stub: reserve unconfigure high memory
Now ACRN support more and more platforms. However, the default configuration only
support board which memory is less than 16 GB. If a board memory is large than
16 GB, the developer needs to configure the memory configuration according to his
board. Otherwise, the boot will fail. This's because UEFI BIOS will use the high
memory as possible.
This patch try to allocate the memory as eraly as possible. So that the BIOS will
not access this region.

Victor Sun 0b65b8f05c Makefile: override .config with specified scenario
1. if SCENARIO=$(SCENARIO) is specified in make param, then override
the default CONFIG_$(SCENARIO) value in existed .config. This means
we don't need to modify the default SCENARIO config in Kconfig file
to build the hypervisor;

2. Some board name shortcuts like apl-nuc/kbl-nuc-i7 need to be converted
to official board name to make sure overrides working;

3. Previously make sbl-hypervisor did not load the defconfig so the
defconfig for boards are lost, this patch fix this issue;

4. remove SCENARIO param when make hypervisor, because SCENARIO could
be got from SCENARIO_NAME which parsed from .config;
