c8aed48127 x86/car: Fix incorrect config usage
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).

b28025a434 cpu/x86/mtrr/mtrr.c:Avoid static scan false positive
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.

7e0dea6317 symbols.h: Add macro to define memlayout region symbols
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.

Currently SMRR msr's are not set on model_1067x and model_6fx since

This will be handled properly in the subsequent parallel mp init

d67edcae6e soc/intel/common: Bring DISPLAY_MTRRS into the light
Initially, I wanted to move only the Kconfig DISPLAY_MTRRS into the

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.

In procedure smm_load_module, variables fxsave_size and fxsave_area are set

the code setting the value to an "else" of the "if" testing CONFIG_SSE, thus

eb5d76a510 smm: Add canary to end of stack and die() if a stack overflow occurs
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.

Stack overflow message:
canary 0x0 != 0xcdeafc00
SMM Handler caused a stack overflow

871156898c smm: Push a null stack base pointer
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.
