As per internal discussion, there's no "ChromiumOS Authors" that's
meaningful outside the Chromium OS project, so change everything to the
contemporary "Google LLC."
While at it, also ensure consistency in the LLC variants (exactly one
trailing period).
"Google Inc" does not need to be touched, so leave them alone.

My CPU (3770k) supports 9 MCE banks, but the code is hardcoded to reset
only 7. This causes Linux to spuriously log errors during boot and S3
resume.
Fix this by reading the real value from the right MSR.

This makes i82801ix use the common smm southbridge code to set up smm
relocation and smi handler setup. This is needed in this change for the
the smm relocation code relies on some southbridge functions provided
in the common code. Some of the old code is kept for the Q35 qemu
target.
This also caches the TSEG region and therefore increases MTRR usage a
little in some cases.
Currently SMRR msr's are not set on model_1067x and model_6fx since this needs
the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled
properly in the subsequent parallel mp init patchset.
Tested on Thinkpad X200: boots and going to and resuming from S3 still
works fine.

extract microcode revision from the given patch.
* get_microcode_size

* get_microcode_checksum

The simpler thing would be to just move the struct microcode

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

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.

Remove locking of PCI device 00:00.0 registers (nehalem/finalize.c)
and remove setting the zeroth bit of the MSR_LT_LOCK_MEMORY = 0x2e7 MSR
register (model_2065x/finalize.c) to fix a frozen boot and S3 resume issue
which became apparent with commit d533b16669a3bacb19b2824e6b4bc76a2a18c92a.
More detailed, either setting the LSB of the 32 bit register at 0x98
of the PCI device 00:00.0 (in the intel_nehalem_finalize_smm function) or
setting the LSB of the the MSR register MSR_LT_LOCK_MEMORY = 0x2e7 (in the
intel_model_2065x_finalize_smm function) indepentenly causes a freeze
during bootup or a complete session loss on resuming from S3 as described
here: https://mail.coreboot.org/pipermail/coreboot/2018-April/086564.html
It seems like Nehalem CPUs do not have a MSR_LT_LOCK_MEMORY register.
Additionally, the "Intel Core i7-600, i5-500, i5-400 and i3-300 Mobile
Processor Series, Datasheet Volume Two" indicates that registers of the
PCI device 00:00.0 cannot be locked manually. Instead, they can only be
locked by TXT, VT-d, CMD.LOCK.MEMCONFIG, ME_SM_LOCK or D_LCK.
Finally, the addresses and sizes of these registers were partially wrong.
Tested on Lenovo X201i with a Core i3 330M (no AES-NI, no VT-d and no TXT
support compared to the Core i5 and Core i7 processors of a X201).

All ARM architecture boards are supposed to have a TTB region for their
page tables. ARM systems cannot use the data cache without enabling
paging, so it is imperative to do that as soon as possible. They will
also fault on unaligned accesses when not using the cache, which breaks
assumptions in CBFS code.
Unfortunately, we have some old boards in various stages of disrepair in
the tree that don't always follow these sorts of standard conventions.
It's not clear whether they actually boot anymore and if anyone still
has the respective hardware available to maintain them. I cannot really
fix and test them right now, but we should at least create a fake TTB
section for them so that common architecture code may make the correct
assumptions about which regions exist.

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.

Add paging_set_default_pat() which sets up the PAT MSR according
to util/x86/x86_page_tables.go. Using page attribute types require
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_enable_pae_cr3(uintptr_t cr3);
void paging_enable_pae(void);
void paging_disable_pae(void);
The functions just enable and/or disable paging along with PAE.
Disassembly shows equivalent output for both versions.

In preparation for bringing in paging early always provide the
paging pae module to all stages. Since we cull unused symbols this
is a no-op. Compilation testing will happen all the time since the module
currently doesn't compile without <arch/cpu.h> include. The current
file is completely guarded with ENV_RAMSTAGE because it's using
cpu_index() which is a ramstage-only construct.
