At the moment we only have two splitting of TSEG,
one with and one without IED. They can all use
same implementation.
Make configuration problems of TSEG region assertion
failures.
Rename file from stage_cache.c to tseg_region.c to
reflect it's purpose.

This patch removes all possible dependencies in order to build platform
with CONFIG_RAMPAYLOAD enable(without ramstage).
A. Create coreboot separate stage kconfigs
This patch creates seperate stage configs as below
1. HAVE_BOOTBLOCK
2. HAVE_VERSTAGE
3. HAVE_ROMSTAGE
4. HAVE_POSTCAR
5. HAVE_RAMSTAGE
B. Also ensures below kconfigs are aligned with correct stage configs
1. COMPRESS_RAMSTAGE and RELOCATABLE_RAMSTAGE are now enable if
CONFIG_HAVE_RAMSTAGE is selected.
2. COMPRESS_BOOTBLOCK will enable if CONFIG_HAVE_BOOTBLOCK is set
3. COMPRESS_PRERAM_STAGES will enable if CONFIG_HAVE_VERSTAGE
|| CONFIG_HAVE_ROMSTAGE is selected.
C. Also fix compilation issue with !CONFIG_HAVE_RAMSTAGE
On x86 platform:
Case 1: ramstage do exist: CONFIG_HAVE_RAMSTAGE=1
>> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_x86_32
Case 2: ramstage doesn't exist: CONFIG_HAVE_RAMSTAGE=0
>> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_
This patch fixes Case 2 usecase where platform doesn't select
CONFIG_HAVE_RAMSTAGE.
Also add option to create sipi_vector.manual based on $(TARGET_STAGE)
variable.
$(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE
$(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD

The initialization logic for the fixed_msrs and msr_index arrays depends
on the contents of the fixed MTRR descriptor. However, Coverity is unable
to check these values and believes (incorrectly) that the arrays may not
be entirely initialized. An assert was added in commit b28025a434 to
ensure that one of the loops is entered, but it is simplest to just
check that msr_num has iterated over the entire array after the loops
are over. This also acts as a sanity check that the values in the MTRR
descriptor were hardcoded correctly.

This IS_ENABLED(XXX) line should've clearly been IS_ENABLED(CONFIG_XXX).
This patch fixes the issue. Not tested on a real board, but looking at
the affected code paths suggests that this will result in no effective
change anywhere (since CAR should already be torn down by the time this
is called on FSP1.0 boards, so do_car_migrate_variables() would have
immediately exited anyway).

Static scan does not know the contents of the fixed MTRR descriptor, so
it has no way to eval the result for variable num_ranges. If num_ranges
is less or equal to 0, the for loop will not be entered, and the values
of fixed_msrs will not be set. Asserting that num_ranges is greater than
0 ensures the loop enters at least once.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

No need to hide it in soc/intel/.
To not bloat src/Kconfig up any further, start a new `Kconfig.debug`
hierarchy just for debug options.
If somebody wants to review the code if it's 100% generic, we could
even get rid of HAVE_DISPLAY_MTRRS.

If CPU 0's stack grows to large, it will overflow into CPU 1's stack.
If CPU 0 is handling the interrupt then CPU 1 should be in an idle loop.
When the stack overflow occurs it will override the return pointer for
CPU 1, so when CPU 0 unlocks the SMI lock, CPU 1 will attempt to return
to a random address.
This method is not foolproof. If code allocates some stack variables
that overlap with the canary, and if the variables are never set, then
the canary will not be overwritten, but it will have been skipped. We
could mitigate this by adding a larger canary value if we wanted.
I chose to use the stack bottom pointer value as the canary value
because:
* It will change per CPU stack.
* Doesn't require hard coding a value that must be shared between the
.S and .c.
* Passing the expected canary value as a parameter felt like overkill.
We can explore adding other methods of signaling that a stack overflow
had occurred in a follow up. I limited die() to debug only because
otherwise it would be very hard to track down.
TEST=built on grunt with a small and large stack size. Then verified
that one causes a stack overflow and the other does not.

When generating a backtrace we need an indicator when we have hit the
beginning of the stack. The i386 ABI states that %ebp points to the next
stack frame. NULL can be used to indicate the end of the stack.
We could add a NULL return pointer at %ebp+4, but I decided to omit it
since a NULL stack pointer can be used as an indicator that there is no
return pointer.

In order to extend the MP callback infrastructure prepare for
easier changes by making the AP callback get signalled by a
single pointer to a local variable on the signaller's stack.
When the APs see the callback they will copy the structure
to a local variable and then set the acknowledgement by
clearing out the slot.
The reading and writing to the slots were implemented using inline
assembly which forces a memory access and a compiler barrier.

When employing PAGING_IN_CACHE_AS_RAM more areas need to be
mapped in at runtime. Therefore, paging_identity_map_addr() is
added to support adding identity mappings. Because there are a
fixed amount of pages in cache-as-ram paging only the existing
paging structures can be used. As such that's a limitation on
what regions and length one can map. Using util/x86/x86_page_tables.go
to generate page tables will always populate all the page directory
pages. Therefore, 2MiB mappings are easy to map in.

Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.
In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.
The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

a matching of the PAT values with the page table entries. This function
is just providing the default PAT MSR value to match against the
utility.

void paging_disable_pae(void);

Disassembly shows equivalent output for both versions.
