b7832de026 x86: Add .data section support for pre-memory stages
x86 pre-memory stages do not support the `.data` section and as a
result developers are required to include runtime initialization code
instead of relying on C global variable definition.

To illustrate the impact of this lack of `.data` section support, here
are two limitations I personally ran into:

1. The inclusion of libgfxinit in romstage for Raptor Lake has
   required some changes in libgfxinit to ensure data is initialized at
   runtime. In addition, we had to manually map some `.data` symbols in
   the `_bss` region.

2. CBFS cache is currently not supported in pre-memory stages and
   enabling it would require to add an initialization function and
   find a generic spot to call it.

Other platforms do not have that limitation. Hence, resolving it would
help to align code and reduce compilation based restriction (cf. the
use of `ENV_HAS_DATA_SECTION` compilation flag in various places of
coreboot code).

We identified three cases to consider:

1. eXecute-In-Place pre-memory stages
   - code is in SPINOR
   - data is also stored in SPINOR but must be linked in Cache-As-RAM
     and copied there at runtime

2. `bootblock` stage is a bit different as it uses Cache-As-Ram but
   the memory mapping and its entry code different

3. pre-memory stages loaded in and executed from
   Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`).

eXecute-In-Place pre-memory stages (#1) require the creation of a new
ELF segment as the code segment Virtual Memory Address and Load Memory
Address are identical but the data needs to be linked in
cache-As-RAM (VMA) but to be stored right after the code (LMA).

Here is the output `readelf --segments` on a `romstage.debug` ELF
binary.

    Program Headers:
      Type    Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
      LOAD    0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20
      LOAD    0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW  0x4

     Section to Segment mapping:
      Segment Sections...
       00     .text
       01     .data

Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they
are totally different for the Segment 1 holding the `.data`
section. Since we need the data section `VirtAddr` to be in the
Cache-As-Ram and its `PhysAddr` right after the `.text` section, the
use of a new segment is mandatory.

`bootblock` (#2) also uses this new segment to store the data right
after the code and load it to Cache-As-RAM at runtime. However, the
code involved is different.

Not eXecute-In-Place pre-memory stages (#3) do not really need any
special work other than enabling a data section as the code and data
VMA / LMA translation vector is the same.

TEST=#1 and #2 verified on rex and qemu 32 and 64 bits:
     - The `bootblock.debug`, `romstage.debug` and
       `verstage.debug` all have data stored at the end of the `.text`
       section and code to copy the data content to the Cache-As-RAM.
     - The CBFS stages included in the final image has not improperly
       relocated any of the `.data` section symbol.
     - Test purposes global data symbols we added in bootblock,
       romstage and verstage are properly accessible at runtime
     #3: for "Intel Apollolake DDR3 RVP1" board, we verified that the
     generated romstage ELF includes a .data section similarly to a
     regular memory enabled stage.

ba7a9eefcf soc/intel/common: Fix invalid MADT entries creation
commit f8ac3dda02 ("soc/intel/common:
Order the CPUs based on their APIC IDs") sort algorithnm walks all the
`cpu_info' entries without discarding empty ones.  Since `cpu_info' is
not initialized, the data that is used is undefined and it generally
results in the creation of invalid `Local x2APIC' entries in the
MADT ("APIC") ACPI table.

Depending on the X2APIC ID value the Linux kernel behavior
changes (cf. arch/x86/kernel/acpi/boot.c::acpi_register_lapic()):
1. If (int)ID >= MAX_LOCAL_APIC (32768), the Linux kernel discards the
   entry with the "skipped apicid that is too big" INFO level
   message.
2. If (int)ID < MAX_LOCAL_APIC (32768) (including negative) this data
   is taken into account and it can lead to undesirable behavior such
   as core being disabled as (cf. "native_cpu_up: bad cpu" ERROR
   kernel message).

TEST=Verified the MADT does not contain any invalid entries on rex.

67d9518586 arch/x86: Don't allow hw floating point operations
Even though coreboot does not allow floating point operations some
compilers like clang generate code using hw floating point registers,
e.g. SSE %XMMx registers on 64bit code by default. Floating point
operations need to be enabled in hardware for this to work (CR4). Also
in SMM we explicitly need to save and restore floating point registers
for this reason. If we instruct the compiler to not generate code with
FPU ops, this simplifies our code as we can skip that step.

With clang this reduces the binary size a bit. For instance ramstage for
qemu/Q35 drops from 216600 bytes decompressed to 212768.

TEST: See that with x86_64 bit and clang coreboot reaches the payload
without setting the CR4_OSFXSR bit in CR4. Without this change it would
bootloop very early in the bootblock on Qemu Q35.

d69ccaf027 arch/x86: Disable walkcbfs_asm code when CONFIG_CBFS_VERIFICATION is set
walkcbfs_asm is a simple CBFS implementation in assembly to find a file
on a system with memory-mapped SPI flash. It seems to be mostly unused
nowadays and is only still called for early microcode loading on some
old systems (e.g. FSP 1.1 and older).

Using this implementation with CONFIG_CBFS_VERIFICATION is unsafe
because it does not verify the hashes the way the normal CBFS code does.
Therefore, to avoid potential security vulnerabilities from creeping in,
this patch makes sure the code cannot be compiled in when
CBFS_VERIFICATION is active. That means it won't be supported on the old
boards using this for microcode loading.

Ideally CONFIG_CBFS_VERIFICATION should have a `depends on` to make this
dependency more obvious in menuconfig, but the configs actually using
this code are not easy to untangle (e.g. CONFIG_MICROCODE_UPDATE_PRE_RAM
is just set everywhere by default although only very few boards are
really using it, and a lot of different old Intel CPU models are linking
in src/cpu/intel/car/non-evict/cache_as_ram.S without being united under
a single Kconfig so that's not easy to change). To keep things simple,
this patch will just prevent the code from being built and result in a
linker error if a bad combination of Kconfigs is used together. Later
patches can clean up the Kconfigs to better wrap that dependency if the
affected boards are still of enough interest to be worth that effort.

ae1b2d49cf soc/intel: Introduce ioapic_get_sci_pin()
According to ACPI Release 6.5 systems supporting PIC (i8259)
interrupt mechanism need to report IRQ vector for the SCI_INT
field. In PIC mode only IRQ0..15 are allowed hardware vectors.

This change should cover section 5.2.9 to not pass SCI_INT
larger than IRQ15. Section 5.2.15.5 needs follow-up work.

Care should be taken that ioapic_get_sci_pin() is called
after platform code has potentially changed the routing
from the default.

It appears touched all platforms except siemens/mc_aplX
currently program SCI as IRQ9.
