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.

The ACPI used for Tiger Lake, Alder Lake and Meteor Lake are very
similar, so can be moved to shared code.
This commit aligns minor difference between then, such as comments and
tabs/spaces.

The EFS data structure diagrams in the Makefiles of Picasso and newer
SoCs were wrong, since the BIOS directory table pointer is in a
different location than shown in the diagram. Since the diagram also
wasn't that easy to understand and amdfwtool does all of that handling,
drop the wrong diagram from the Makefiles.

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.
