5b5f1735ff acrnboot: fix the parsing hv_cmdline to correctly handle the case of containing trailing whitespaces
The pointer variable 'start' should be checked against NULL
    right after detected it is not pointer to a space character,
    otherwise the pointer variable 'end' must hold the wrong
    address right after NULL if the cmdline containing trailing
    whitespaces and deference the wrong address out of cmdline
    string. this parsing code also been optimized and simplified.

3c8d465a11 acrnboot: correct the calculation of the end boundry of _DYNAMIC region
The calculation of the end boundry address is corrected by
    adding the size extracted from _DYNAMIC to start address
    in type of uint8_t while improving the code by calulating
    the end boundry address after scanning, also reducing type
    casts accordingly.

15da33d8af HV: parse default pci mmcfg base
The default PCI mmcfg base is stored in ACPI MCFG table, when
CONFIG_ACPI_PARSE_ENABLED is set, acpi_fixup() function will
parse and fix up the platform mmcfg base in ACRN boot stage;
when it is not set, platform mmcfg base will be initialized to
DEFAULT_PCI_MMCFG_BASE which generated by acrn-config tool;

Please note we will not support platform which has multiple PCI

9e92f3cdf5 HV: move dmar info definition to board.c
The DMAR info is board specific so move the structure definition to board.c.
As a configruation file, the whole board.c could be generated by acrn-config
tool for each board.

Please note we only provide DMAR info MACROs for nuc7i7dnb board. For other
boards, ACPI_PARSE_ENABLED must be set to y in Kconfig to let hypervisor parse
DMAR info, or use acrn-config tool to generate DMAR info MACROs if user won't
enable ACPI parse code for FuSa consideration.

The patch also moves the function of get_dmar_info() to vtd.c, so dmar_info.c
could be removed.

also ramdisk image. To resolve this problem, we will use a tag in
mods mm_string field to specify the module type. If the tag could
be matched with os_config of VM configurations, the corresponding

cee2f8b288 ACRN/HV: Refine the function of init_vboot to initialize the depriv_boot env correctly
Currently when get_rsdp is called, the EFI depriv_boot env is not initialized.
In such case it will fallback to the legacy mechanism of ACPI table.
If the ACPI table based on legacy mechanism is not found, it will fail to get
the ACPI table and then the system will hang.
On the old platform it still can parse the ACPI table from legacy mechanism.
In fact when EFI RSDP exists, the EFI RSDP is preferred instead of legacy ACPI
RSDP.

In order to avoid multiple calling of depriv_init_boot, the init_boot_operations
is renamed and called after X2apic is enabled(early_init_lapic).

238d8bbaa2 reshuffle init_vm_boot_info
now only SOS need decide boot with de-privilege or direct boot mode, while
for other pre-launched VMs, they should use direct boot mode.

this patch merge boot/guest/direct_boot_info.c &
boot/guest/deprivilege_boot_info.c into boot/guest/vboot_info.c,
and change init_direct_vboot_info() function name to init_general_vm_boot_info().

in init_vm_boot_info(), depend on get_sos_boot_mode(), SOS may choose to init
vm boot info by setting the vm_sw_loader to deprivilege specific one; for SOS
using DIRECT_BOOT_MODE and all other VMS, they will use general_sw_loader as
vm_sw_loader and go through init_general_vm_boot_info() for virtual boot vm
info filling.

this patch also move spurious handler initilization for de-privilege mode from
boot/guest/deprivilege_boot.c to boot/guest/vboot_info.c, and just set it in
deprivilege sw_loader before irq enabling.

20f97f7559 restruct boot and bsp dir for firmware stuff
currently, ACRN hypervisor can either boot from sbl/abl or uefi, that's
why we have different firmware method under bsp & boot dirs.
but the fact is that we actually have two different operations based on
different guest boot mode:
1. de-privilege-boot: ACRN hypervisor will boot VM0 in the same context as
native(before entering hypervisor) - it means hypervisor will co-work with
ACRN UEFI bootloader, restore the context env and de-privilege this env
to VM0 guest.
2. direct-boot: ACRN hypervisor will directly boot different pre-launched
VM(including SOS), it will setup guest env by pre-defined configuration,
and prepare guest kernel image, ramdisk which fetch from multiboot modules.

this patch is trying to:
- rename files related with firmware, change them to guest vboot related
- restruct all guest boot stuff in boot & bsp dirs into a new boot/guest dir
- use de-privilege & direct boot to distinguish two different boot operations

this patch is pure file movement, the rename of functions based on old assumption will
be in the following patch.

a0de49d03e hv: fix potential buffer overflow in sbl_init_vm_boot_info()
To merge the multiboot bootargs within sbl_init_vm_boot_info(), buffer
overflow could happen when it doesn't provide correct 'dmax' argument
to strncpy_s().

Also, currently it doesn't check the availability of the dest buffer before
overwriting '\0' with a whitespace, which theoretically the dest string
could end up with no null terminator within it's array boundary.

This patch also creates a separate function to merge the cmdline strings,
because after the above fixes some lines in sbl_init_vm_boot_info()
function could have up to 7 tabs in front of the first character, which
looks messy and sbl_init_vm_boot_info() is getting too complicated.

5c04687967 hv: minor fixes to a few calls to strncpy_s()
strncpy_s(d, dmax, s, slen): the 'dmax' includes the null terminator, while
slen doesn't. Thus if (dmax == slen == strlen(s)), strncpy_s() chooses to
discard the last character from s and instead write '\0' to d[dmax - 1].

strnlen_s(s, maxsize): if there is no terminating null character in the
first maxsize characters pointed to by s, strnlen_s() returns maxsize.

So in the following example or similar cases, we need to increase the size
of d[] by 1 to accommodate the null terminator, and add '1' to the dmax
argument to strncpy_s().

uint8_t d[MAX_LEN];
size = strnlen_s(s, MAX_LEN);
strncpy_s(d, MAX_LEN, s, size);

518a82d80b hv: cleanup some hva/hpa conversion code
The init page tables installed in either cpu_primary.S or trampoline.S

The 'actual' hypervisor page table installed in enable_paging() is 1:1
mapping currently but it could be changed in the future. Both hva2hpa() and
hpa2hva() are implemented based on these page tables and can't be used
when the init page tables take effect.

This patch does the following cleanup:

- remove all hva2hpa()/hpa2hva() before calling enable_paging()
- get_hv_image_base() returns HVA, not HPA. So add hva2hpa() for all cases
  that are called afte enable_paging().

In terms of parsing multboot info, the differences between pre-launched VM
and SOS are minor:

- pre-launched VMs don't take bootargs from multiboot info.
- The kernel_load_addr is different between pre-launched VMs and SOS.

This patch removes the partition mode specific init_vm_boot_info(), and
handle SOS and pre-launched VMs differently in one single init_vm_boot_info().

Also, this makes ramdisk available for pre-launched VMs.

cf1515d63c hv: optimize the assignment of load addresses for multiboot images
bootargs_load_addr (GPA) and zero page which locates at one page follows it:
- SOS: currently it's fixed at 0x24EFC000. Theoretically, this address may
  not exist if the system has small memory size.
- pre-launched VMs: currently it's at (vm_config->memory.size - 8KB).
  It doesn't work if the guest has been assigned for more than 4GB memory
  size, because zero page must be under 4GB.
- This patch reserves 8KB for bootargs_load_addr right before kernel_load_addr
  for either SOS or pre-launched VMs.

ramdisk_load_addr (GPA):
- pre-launched VMs: currently it doesn't allow ramdisk.
- SOS: currently it's assigned at mods[].mm_mod_start. It's a bug because it
  misses the hpa2gpa() conversion.
- This patch puts ramdisk_load_addr right after (kernel_load_addr + kernel_size),
  which has 2 benefits:
  - for pre-launched VMs, mods[].mm_mod_start may be out of its GPA range.
  - it may be better to consolidate everything (bootarg, kernel, ramdisk) in
    consecutive GPA, other than spread them out in different places.

584f6b7255 doc: replace return with retval
`@return` is dedicated for brief description of return values, not for comments
stating actual return values. In addition, sphinx + breathe does not join
multiple adjacent `@return`. This results in multiple `Return` sections in the
generated document, which is confusing.

This patch replaces `@return` with `@retval` for the lists of return
values. Adjacent `@retval` can be joined into one list by breathe.

v1 -> v2:

* Replace return value descriptions like `negative` and `positive` with
  expressions like `<0` and `>0` in `@retval`.
* Keep the list of `@retval` comprehensive, even when there is a `@return` to
  generally describe what the return value means.
* Drop duplicated `@return` when it does not give more information than the
  `@retval` list.

Tables that contain simple data and no AML byte code. These types of tables
are known as ACPI Data Tables. They include tables such as the FADT, MADT,
ECDT, SRAT, etc. -essentially any table other than a DSDT or SSDT.

The second type of table, the ACPI Data Table, could be parsed here.

a71dedecd4 hv: treewide: fix 'Array has no bounds specified'
MISRAC requires that the array size should be declared explicitly.

This patch fixes the issues caused by the arrays that are defined in
link_ram.ld.in or assembly file.

v1 -> v2:
 * Update the solution based on the info from the following link.
   https://sourceware.org/binutils/docs/ld/Source-Code-Reference.html

   Fix pattern is like below:
   extern char start_of_ROM, end_of_ROM, start_of_FLASH;
   memcpy (& start_of_FLASH, & start_of_ROM, & end_of_ROM - &
start_of_ROM);

This patch corrects the behavior when CONFIG_RELOC is disabled
- Don't use "CFLAGS += -fpie" and put back "LDFLAGS += -static"
- __emalloc(): forced to allocate exactly the asked address, which is

c808972926 hv: fix the potential dead loop in _parse_madt
With current implementation:
If the case 'entry->length < sizeof(struct acpi_subtable_header)' is
triggered, it will lead to a dead loop.

What this patch does:
Gracefully return when this case is triggered.

Why:
If 'entry->length < sizeof(struct acpi_subtable_header)', it means that
there is no valid 'struct acpi_subtable_header' starting from the entry.
There must be something wrong. It should not happen in normal case.

v1 -> v2:
 * Remove the unacceptable ASSERT, just gracefully return

cb0009f4d2 hv: cpu: fix 'Pointer arithmetic is not on array'
Use the array for lapic_id directly to avoid the unnecessary pointer
arithmetic.

With current implementation,
  lapic_id_base is always a byte array with CPU_PAGE_SIZE elements

What this patch does:
 - replace 'uint8_t *lapic_id_base' with 'uint8_t
   lapic_id_array[CPU_PAGE_SIZE]' to make the boundary explicit
 - add a range check to ensure that there is no overflow

 v2 -> v3:
 * update the array size of lapic_id_array per discussion with Fengwei

 v1 -> v2:
 * remove the unnecessary range check in parse_madt in cpu.c
