Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper
function around enable_cache which additionally wrote a POST code to
port 0x80 and printed a message to the console. This function was only
called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.
This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.

Since all x86 CPUs in tree have MTRR support, there is no need to guard
the DISPLAY_MTRRS option with HAVE_DISPLAY_MTRRS. Also all x86 CPUs/SoCs
have a display_mtrrs call at least somewhere in their code, so selecting
the DISPLAY_MTRRS option will always have an effect. All SoCs that don't
select RESET_VECTOR_IN_RAM have the postcar stage where it gets called.
The two AMD SoCs that select RESET_VECTOR_IN_RAM use the FSP2 driver
which contains plenty of display_mtrrs calls.

With using a Kconfig option to add the x86 LAPIC support code to the
build, there's no need for adding the corresponding directory to subdirs
in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added
(cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding
MTRR code selection patch and having verified that all platforms
added the MTRR code on that patch shows that soc/example/min86 and
soc/intel/quark are the only platforms that don't end up selecting the
LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y
which gets overridden to n in the Kconfig of the two SoCs mentioned
above.

All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.
In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs
in their Makefiles.

Each CPU/SoC checks the return value of the mp_init_with_smm and prints
the same error message if it wasn't successful, so move this check and
printk to mp_init_with_smm. For this the original mp_init_with_smm
function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm
function is created which then calls do_mp_init_with_smm, prints the
error if it didn't return CB_SUCCESS and passes the return value of
do_mp_init_with_smm to its caller.
Since no CPU/SoC code handles a mp_init_with_smm failure apart from
printing a message, also add a comment at the mp_init_with_smm call
sites that the code might want to handle a failure.

There are two possible code sections where the cpu_info macros can be
included: .code32 and .code64
Doing a `push %eax` while in a .code64 section will result in a compiler
error. This macro manually pushes the 32-bit register onto the stack so
we can share the code between 32 and 64 bit builds.
We also can't implicitly dereference per_cpu_segment_selector because
it's a 32-bit address. Trying to do this results in the following:
E: Invalid reloc type: 11
E: Illegal use of 32bit sign extended addressing at offset 0x1b2
If we load the address first, then dereference it, we can work around
the limitation.
With these fixes, 64-bit builds can now use CPU_INFO_V2.

When CONFIG_X86_AMD_INIT_SIPI was set, the second/final SIPI that
afterwards checks if all APs have checked in was skipped and if it got
so far, start_aps returned CB_SUCCESS despite not having checked if all
APs had checked in after the SIPI. This patch makes start_aps skip the
first SIPI in the CONFIG_X86_AMD_INIT_SIPI case so we use the proper
timeouts and error handling for the final and this case only SIPI and
signal the caller an error when not all APs have checked in after the
SIPI.
A timeless build for lenovo/x230 which is a mainboard that doesn't
select X86_AMD_INIT_SIPI results in identical binary, so this doesn't
change the behavior of the !X86_AMD_INIT_SIPI case.

There is currently a fundamental flaw in the current cpu_info()
implementation. It assumes that current stack is CONFIG_STACK_SIZE
aligned. This assumption breaks down when performing SMM relocation.
The first step in performing SMM relocation is changing the SMBASE. This
is accomplished by installing the smmstub at 0x00038000, which is the
default SMM entry point. The stub is configured to set up a new stack
with the size of 1 KiB (CONFIG_SMM_STUB_STACK_SIZE), and an entry point
of smm_do_relocation located in RAMSTAGE RAM.
This means that when smm_do_relocation is executed, it is running in SMM
with a different sized stack. When cpu_info() gets called it will be
using CONFIG_STACK_SIZE to calculate the location of the cpu_info
struct. This results in reading random memory. Since cpu_info() has to
run in multiple environments, we can't use a compile time constant to
locate the cpu_info struct.
This CL introduces a new way of locating cpu_info. It uses a per-cpu
segment descriptor that points to a per-cpu segment that is allocated on
the stack. By using a segment descriptor to point to the per-cpu data,
we no longer need to calculate the location of the cpu_info struct. This
has the following advantages:
* Stacks no longer need to be CONFIG_STACK_SIZE aligned.
* Accessing an unconfigured segment will result in an exception. This
ensures no one can call cpu_info() from an unsupported environment.
* Segment selectors are cleared when entering SMM and restored when
leaving SMM.
* There is a 1:1 mapping between cpu and cpu_info. When using
COOP_MULTITASKING, a new cpu_info is currently allocated at the top of
each thread's stack. This no longer needs to happen.
This CL guards most of the code with CONFIG(CPU_INFO_V2). I did this so
reviewers can feel more comfortable knowing most of the CL is a no-op. I
would eventually like to remove most of the guards though.
This CL does not touch the LEGACY_SMP_INIT code path. I don't have any
way of testing it.
The %gs segment was chosen over the %fs segment because it's what the
linux kernel uses for per-cpu data in x86_64 mode.

The %fs and %gs segment are typically used to implement thread local
storage or cpu local storage. We don't currently use these in coreboot,
so there is no reason to map them. By setting the segment index to 0,
it disables the segment. If an instruction tries to read from one of
these segments an exception will be raised.
The end goal is to make cpu_info() use the %gs segment. This will remove
the stack alignment requirements and fix smm_do_relocation.

be 2048 bytes. The fix is to change the result of the subtraction to a
signed type, and ensure the following comparison is done without
promoting the signed type to an unsigned one.

Introduce the `ARCH_ALL_STAGES_X86` Kconfig symbol to automatically
select the per-stage arch options. Subsequent commits will leverage
this to allow choosing between 32-bit and 64-bit coreboot where all
stages are x86. AMD Picasso and AMD Cezanne are the only exceptions
to this rule: they disable `ARCH_ALL_STAGES_X86` and explicitly set
the per-stage arch options accordingly.

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.

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.
