V1->V2: removed the unneccesary cache flushing
- For UEFI boot, allocate memory for trampoline code in ACRN EFI,
and pass the pointer to HV through efi_ctx
- For other boot, scan E820 to allocate memory in HV run time
- update_trampoline_code_refs() updates all the references that need the

V2->V3: Fixed the booting issue on MRB board and removed the restriction
of allocate memory from address 0
1) Fix the booting from MRB issue
-#define CONFIG_LOW_RAM_SIZE 0x000CF000
+#define CONFIG_LOW_RAM_SIZE 0x00010000
2) changed e820_alloc_low_memory() to handle corner case of unaligned e820 entries
and enable it to allocate memory at address 0
+ a length = end > start ? (end - start) : 0;
- /* We don't want the first page */
- if ((length == size) && (start == 0))
- continue;
3) changed emalloc_for_low_mem() to enable to allocate memory at address 0
- /* We don't want the first page */
- if (start == 0)
- start = EFI_PAGE_SIZE;
V1->V2: moved e820_alloc_low_memory() to guest.c and added the logic to
handle unaligned E820 entries
emalloc_for_low_mem() is used if CONFIG_EFI_STUB is defined.
e820_alloc_low_memory() is used for other cases
In either case, the allocated memory will be marked with E820_TYPE_RESERVED

V1->V2: removed CONFIG_LOW_RAM_START and added ".org 0" to
cpu_secondary.S
The assumption is trampoline code is relocated while HV is not, so:
trampoline code is built at address 0, and CS register is updated
by SIPI to reflect the correct vector
in real mode part, added extra pointers for page tables and long jump buffer
so it's possible for HV code to patch the relocation offset
in long mode part, use absolute addressing when referring HV symbols,
and use relative addressing for symbols within trampoline code

The current dm, all non-pci and non-acpi related files are put into
hw/platform directory. This is actually disturbed the meaning of
*platform*. The platform devices are mean of board and SoC specific
non-PCI devices, like usb devices, etc.
This patch refines the ACRN dm directory architecture.
For some common device logic files, likes block_if.c/uart_core.c or
usb_core.c. They will move to hw/ directly.
For platform architecture depended files, create arch/ under root dir.
And create sub-dir arch/x86 for x86 architecture, will create more
architectures in future. The pm.c will move to this new dir.
The hw/acpi will be moved to hw/platform/acpi due to acpi also be
considered as part of platform.

The original code assume there is only one configuration for
virtio-blk, and 'b' is just located after that configuration,
so to get the value of 'b', it will end char *config by adding
'\0' after the first configuration.
Thus, char *config will change from:
/XXXX_vdisk_file,range=xxx/xxx
to:
/XXXX_vdisk_file
and char *b will point to:
range=xxx/xxx
So, the range will never take effect for virtio-blk.
Now, 'b' is designed to located just after emul, and
char *config will point to all configurations after 'b'.
Note: only ",b," is taken for boot device option.

This patch makes the Service OS bootloader configurable by passing
a command-line argument to 'acrn.efi' when setting up the EFI
bootloader using, e.g., 'efibootmgr'. If no argument is passed, the
default bootloader used is: "\EFI\org.clearlinux\bootloaderx64.efi".
This is the default bootloader/setting used by Clearlinux and is set
in the bsp/uefi/include/bsp/bsp_cfg.h file (via the
CONFIG_UEFI_OS_LOADER_NAME define)
The general format of the argument is: "bootloader=<\path\to\bootloader>".
As a concrete example, imagine the following set-up:
* You have installed the Service OS (bare-metal for now)
* Bootloader is "\EFI\org.clearlinux\bootloaderx64.efi"
* Boot device is '/dev/sda'
* EFI System Partition (ESP) is '1'
* You put the ACRN hypervisor under "\EFI\acrn\"
To change the default boot entry to boot the ACRN hypervisor, enter:
# efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/sda -p 1 \
-L "ACRN Hypervisor" -u "bootloader=\EFI\org.clearlinux\bootloaderx64.efi"
And reboot your machine.
