Victor Sun 1b3a75c984 HV: place kernel and ramdisk by find_space_from_ve820()
We should not hardcode the VM ramdisk load address right after kernel
load address because of two reasons:
	1. Per Linux kernel boot protocol, the Kernel need a size of
	   contiguous memory(i.e. init_size field in zeropage) from
	   its load address to boot, then the address would overlap
	   with ramdisk;
	2. The hardcoded address could not be ensured as a valid address
	   in guest e820 table, especially with a huge ramdisk;

Also we should not hardcode the VM kernel load address to its pref_address
which work for non-relocatable kernel only. For a relocatable kernel,
it could run from any valid address where bootloader load to.

The patch will set the VM kernel and ramdisk load address by scanning
guest e820 table with find_space_from_ve820() api:
	1. For SOS VM, the ramdisk has been loaded by multiboot bootloader
	   already so set the load address as module source address,
	   the relocatable kernel would be relocated to a appropriate address
	   out space of hypervisor and boot modules to avoid guest memory
	   copy corruption;
	2. For pre-launched VM, the kernel would be loaded to pref_address
	   first, then ramdisk will be put to a appropriate address out space
	   of kernel according to guest memory layout and maximum ramdisk
	   address limit under 4GB;

Thus the vboot wrapper layer can be removed and the direct boot functions
don't need to be wrapped in direct_boot.c:

- remove call to init_vboot(), and call e820_alloc_memory() directly at the
  time when the trampoline buffer is actually needed.
- Similarly, call CPU_IRQ_ENABLE() instead of the wrapper init_vboot_irq().
- remove get_ap_trampoline_buf(), since the existing function
  get_trampoline_start16_paddr() returns the exact same value.
- merge init_general_vm_boot_info() into init_vm_boot_info().
- remove vm_sw_loader pointer, and call direct_boot_sw_loader() directly.

Previously the VM kernel bootargs for pre-launched VMs and direct boot mode
of SOS VM are built-in hypervisor binary so end users have no way to change
it. Now we provide another option that the multiboot module string could be
used as bootargs also. This would bring convenience to end users when they
use GRUB as bootloader because the bootargs could be configurable in GRUB
menu.

The usage is if there is any string follows configured kernel_mod_tag in
module string, the string will be used as new kernel bootargs instead of
built-in kernel bootargs. If there is no string follows kernel_mod_tag,
then the built-in bootargs will be the default kernel bootargs.

Please note kernel_mod_tag must be the first word in module string in any
case, it is used to specify the module for which VM.

Victor Sun c74b1941a0 HV: split sanitize_multiboot_info api
Previously sanitize_multiboot_info() was called after init_debug_pre() because
the debug message can only print after uart is initialized. On the other hand,
multiboot cmdline need to be parsed before init_debug_pre() because the cmdline
could override uart settings and make sure debug message printed successfully.
This cause multiboot info was parsed in two stages.

The patch revise the multiboot parse logic that split sanitize_multiboot_info()
api and use init_acrn_multiboot_info() api for the early stage. The most of
multiboot info will be initialized during this stage and no debug message need
to be printed. After uart is initialized, the sanitize_multiboot_info() would

Li Fei1 4eb3f5a0c7 hv: vacpi: add fadt table support
Add FADT table support to support guest S5 setting.

According to ACPI 6.3 Spec, OSPM must ignored the DSDT and FACS fields if them're zero.
However, Linux kernel seems not to abide by the protocol, it will check DSDT still.
So add an empty DSDT to meet it.

Sainath Grandhi f67ac09141 hv: Handle holes in GSI i.e. Global System Interrupt for multiple IO-APICs
MADT is used to specify the GSI base for each IO-APIC and the number of
interrupt pins per IO-APIC is programmed into Max. Redir. Entry register of
that IO-APIC.

On platforms with multiple IO-APICs, there can be holes in the GSI space.
For example, on a platform with 2 IO-APICs, the following configuration has
a hole (from 24 to 31) in the GSI space.

IO-APIC 1: GSI base - 0, number of pins - 24
IO-APIC 2: GSI base - 32, number of pins - 8

This patch also adjusts the size for variables used to represent the total
number of IO-APICs on the system from uint16_t to uint8_t as the ACPI MADT
uses only 8-bits to indicate the unique IO-APIC IDs.

Zide Chen 49ffe168af hv: fixup relocation delta for symbols belong to entry section
This is to enable relocation for code32.

- RIP relative addressing is available in x86-64 only so we manually add
  relocation delta to the target symbols to fixup code32.

- both code32 and code64 need to load GDT hence both need to fixup GDT
  pointer. This patch declares separate GDT pointer cpu_primary64_gdt_ptr
  for code64 to avoid double fixup.

- manually fixup cpu_primary64_gdt_ptr in code64, but not rely on relocate()
  to do that. Otherwise it's very confusing that symbols from same file could
  be fixed up externally by relocate() or self-relocated.

- to make it clear, define a new symbol ld_entry_end representing the end of
  the boot code that needs manually fixup, and use this symbol in relocate()
  to filter out all symbols belong to the entry sections.

Chen, Zide 2aa8c9e5d4 hv: add multiboot2 tags to load relocatable raw binary
GRUB multiboot2 doesn't support relocation for ELF, which means it can't
load acrn.32.out to other address other than the one specified in ELF
header. Thus we need to use the raw binary file acrn.bin, and add
address/entry address/relocatable tags to instruct multiboot2 loader
how to load the raw binary.
