Trigger mode LAPIC_INT_LEVELTRIG was only used with LAPIC_DM_INIT,
specifically for (obsolete) Init Level De-assert.
Level LAPIC_INT_ASSERT is required to be set for all other delivery
modes other than LAPIC_DM_INIT.
This reverts the two above changes that X2APIC mode support introduced
to the IPI for LAPIC_DM_SMI.

Fix compilation on x86_64 by using compatible types.
The MRC blob isn't supported yet as there's no x86_32 wrapper.
Tested on HP8200:
* Still boots on x86_32.
* Boots to payload in x86_64

In x86_64 code every function call consumes 32byte of stack with
no stack local variables being used. That limits the function call depth
in SMM to 32 or less.
Double the stack size to prevent overwriting the stack canary as seen
on HP8200 and x86_64 enabled.

This fixes a hard to debug hang that could occur in any stage, but in
the end it follows simple rules and is easy to fix.
In long mode the 32bit displacement addressing used on 'mov' and 'lea'
instructions is sign-extended. Those instructions can be found using
readelf on the stage and searching for relocation type R_X86_64_32S.
The sign extension is no issue when either running in protected mode or
the code module and thus the address is below 2GiB. If the address is
greater than 2GiB, as usually the case for code in TSEG, the higher
address bits [64:32] are all set to 1 and the effective address is
pointing to memory not paged. Accessing this memory will cause a page
fault, which isn't handled either.
To prevent such problems
- disable R_AMD64_32S relocations in rmodtool
- add comment explaining why it's not allowed
- use the pseudo op movabs, which doesn't use 32bit displacement addressing
- Print a useful error message if such a reloc is present in the code
Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

Allows compile-time optimisation on platforms that do not wish
to enable runtime checking of X2APIC.
Legacy lapic_cpu_init() is incompatible so there is dependency
on PARALLEL_MP. Also stop_this_cpu() is incompatible, so there
is dependency on !AP_IN_SIPI_WAIT.
Since the code actually lacks enablement of X2APIC (apparently
assuming the blob has done it) and the other small flaws pointed
out in earlier reviews, X2APIC_RUNTIME is not selected per
default on any platform yet.

Create the correct MTRR solution based on the physical address space
provided by RESOURCE_ALLOCATOR_V4. Previously CPU initialization did not
account for lost C6 DRAM storage MTRR during postcar frame creation.
The BSP on 2GB has been stripped from UC MTRR covering C6 DRAM and
overlapping with usable DRAM WB MTRR. However this UC MTRR remained on
APs which caused inconsistent MTRRs warning in Linux. Use generic MTRR
function to create correct MTRR solution that propagates to APs. This
also fixes the inconsistent MTRRs warning.

This patch removes a call to console_init() and debug print message since
the code is not thread safe. This prevents system hangs (soft hangs)
while in SMM if user drops in a new SOC with more cores or another
socket or as a result of bad configuration. Console is already
initialized after the lock has been acquired so this does not affect any
other functionality.

Some platforms which have large amounts of RAM and also write-combining
regions may decide to drop the WC regions in favor of the default when
preserving MTRRs for the OS. From a data safety perspective, this is
safe to do, but if, say, the graphics framebuffer is the region that is
changed from WC to UC/WB, then the performance of writing to the
framebuffer will decrease dramatically.
Modern OSes typically use Page Attribute Tables (PAT) to determine the
cacheability on a page level and usually do not touch the MTRRs. Thus,
it is believed to be safe to stop reserving MTRRs for the OS, in
general; PentiumII is the exception here in that OSes that still
support that may still require MTRRs to be available. In any case, if
the OS wants to reprogram all of the MTRRs, it is of course still free
to do so (after consulting the e820 table).

Use the same stack location during relocation as for the permanent

When the number of CPUs is too large the stacks during relocation
don't fit inside the default SMRAM segment at 0x30000. Currently the
code would just let the CPU stack base grow downwards outside of the
default SMM segment which would corrupt lower memory if S3 is
implemented.
Also update the comment on smm_module_setup_stub().

With CBnT a digest needs to be made of the IBB, Initial BootBlock, in
this case the bootblock. After that a pointer to the BPM, Boot Policy
Manifest, containing the IBB digest needs to be added to the FIT
table.
If the fit table is inside the IBB, updating it with a pointer to the
BPM, would make the digest invalid.
The proper solution is to move the FIT table out of the bootblock.
The FIT table itself does not need to be covered by the digest as it
just contains pointers to structures that can by verified by the
hardware itself, such as microcode and ACMs (Authenticated Code
Modules).

In pursuit of the eventual goal of removing cbfs_boot_locate() (and
direct rdev access) from CBFS APIs, this patch replaces all remaining
"simple" uses of the function call that can easily be replaced by the
newer APIs (like cbfs_load() or cbfs_map()). Some cases of
cbfs_boot_locate() remain that will be more complicated to solve.

Since prog_locate() was eliminated, prog_rdev() only ever represents the
loaded program in memory now. Using the rdev API for this is unnecessary
if we know that the "device" is always just memory. This patch changes
it to be represented by a simple pointer and size. Since some code still
really wants this to be an rdev, introduce a prog_chain_rdev() helper to
translate back to that if necessary.

CB:49896 added support in `intel_microcode_find()` to cache the found
microcode for faster subsequent accesses. This works okay when the
function succeeds in finding the microcode on BSP. However, if for any
reason, `cpu_microcode_blob.bin` does not contain a valid microcode
for the given processor, then the logic ends up attempting to find
microcode again and again every time it is called (because
`ucode_updates` is set to NULL on failed find, thus retriggering the
whole find sequence every time). This leads to a weird race condition
when multiple APs are running in parallel and executing this
function.
A snippet of the issues observed in the scenario described above:
```
...
microcode: Update skipped, already up-to-date
...
Microcode header corrupted!
...
```
1. AP reports that microcode update is being skipped since the current
version matches the version in CBFS (even though there is no matching
microcode update in CBFS).
2. AP reports microcode header is corrupted because it thinks that the
data size reported in the microcode is larger than the file read from
CBFS.
Above issues occur because each time an AP calls
`intel_microcode_find()`, it might end up seeing some intermittent
state of `ucode_updates` and taking incorrect action.
This change fixes this race condition by separating the logic for
finding microcode into an internal function `find_cbfs_microcode()`
and maintaining the caching logic in `intel_microcode_find()` using a
boolean flag `microcode_checked`.
BUG=b:182232187
TEST=Verified that `intel_microcode_find()` no longer makes repeated
attempts to find microcode from CBFS if it failed the first time.

CPUID result does not change when HyperThreading is disabled on
HT-enabled CPUs, which breaks `generate_cpu_entries`. Use MSR 0x35
instead, which returns the currently-enabled core and thread count.
Also rename the function to `get_logical_cores_per_package, which is
more accurate. Based on commit 920d2b77f2 (cpu/intel/206ax/acpi.c: Fix
get_cores_per_package). The MSR definition is the same for Sandy Bridge
and Haswell.
