APs use a lot less stack, so set up a separate stack for those in .bss.
Now that CPU_INFO_V2 is the only code path that is used, there is no
need to align stacks in c_start.S.

After the previous patch this local variable is no longer the mpinit CPU
index, but the LAPIC ID, so rename it. Since it will only be set once,
it can also be marked as const.

The cpu_index function can't be used before mpinit, so use lapicid calls
instead. This fixes the regression introduced by commit 4c3749884d71
("cpu/x86/mtrr: Print cpu index number when set up MTRRs for BSP/APs")
and also reverts also commit b3261661c703 ("cpu/x86/mtrr/mtrr: fix
printk format strings"), since lapicid returns an unsigned int while
cpu_index returns an unsigned long.

Commit 4c3749884d71 ("cpu/x86/mtrr: Print cpu index number when set up
MTRRs for BSP/APs") added the CPU index number to some prints, but used
%x as format specifier. The cpu_index() call however has a return type
of unsigned long, so %lx needs to be used instead. For consistency, also
change the type of the cpu_idx local variable in commit_fixed_mtrrs to
unsigned long and adjust the printk format specifier accordingly.

There are four requirements for the SMI to hit a printk()
this commit now removes.
Build must have DEBUG_SMI=y, otherwise any printk() is a no-op
inside SMM.
ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value.
Platform needs to have IO Trap #3 enabled at IO 0x800.
The SMI monitor must call io_trap_handler for IO Trap #3.
At the moment, only getac/p470 would meet the above criteria
with TRAP(0x32) in its DSDT _INI method. The ASL ignores any
return value of TRAP() calls made.
A mainboard IO trap handler should have precedence over
a southbridge IO trap handler. At the moment we seem to have
no cases of the latter to support, so remove the latter.

This code was never tested with SSE enabled. Now qemu enables it and
FX_SAVE encroaches on the save states. Without SSE enabled the handler
just happened to be aligned downwards enough to have the save states
fit. With SSE enabled that's not the case. The proper fix is to give the
code setting up stubs the right base address, which is the same as for
the TSEG codepath.

AMD CPUs have a convenient MSR that allows to set the SMBASE in the save
state without ever entering SMM (e.g. at the default 0x30000 address).
This has been a feature in all AMD CPUs since at least AMD K8. This
allows to do relocation in parallel in ramstage and without setting up a
relocation handler, which likely results in a speedup. The more cores
the higher the speedup as relocation was happening sequentially. On a 4
core AMD picasso system this results in 33ms boot speedup.
TESTED on google/vilboz (Picasso) with CONFIG_SMI_DEBUG: verify that SMM
is correctly relocated with the BSP correctly entering the smihandler.

This code was hard to read as it did too much and had a lot of state
to keep track of.
It also looks like the staggered entry points were first copied and
only later the parameters of the first stub were filled in. This
means that only the BSP stub is actually jumping to the permanent
smihandler. On the APs the stub would jump to wherever c_handler
happens to point to, which is likely 0. This effectively means that on
APs it's likely easy to have arbitrary code execution in SMM which is a
security problem.

Currently no smihandler uses heap.
coreboot's heap manager also is quite limited in what it will
free (only the latest alloc). This makes it a bad idea to use it inside
the smihandler, as depending on the alloc usage the heap might actually
be full at some point, breaking the smihandler.
This also reduces the ramstage by 448 bytes on google/vilboz.

This patch delays removing `temporary` MTRR snapshots to avoid conflicts
with other operations attached with same `BS_PAYLOAD_BOOT/BS_ON_EXIT`
boot state.
BUG=b:225766934
TEST=Having variable MTRR snapshot using display_mtrrs() is able to
list only the permanent MTRRs and all temporary MTRRs are removed
prior to boot to payload.

This patch migrates a few useful MTRR functions as below from
`earlymtrr.c` file to newly created common stage file `mtrrlib.c`.
1. get_free_var_mtrr
2. set_var_mtrr
3. clear_all_var_mtrr
These functions can be used to perform the MTRR programming from IA
common code SPI driver as `fast_spi.c` without requiring two separate
implementations for early boot stage (till romstage) and for ramstage
onwards.

This change provides hooks for the SoC so it can perform any
initialization and cleanup in the SMM handler.
For example, if we have a UART enabled firmware with DEBUG_SMI, the UART
controller could have been powered off by the OS. In this case we need
to power on the UART when entering SMM, and then power it off before we
exit. If the OS had the UART enabled when entering SMM, we should
snapshot the UART register state, and restore it on exit. Otherwise we
risk clearing some interrupt enable bits.

This change will allow the SMI handler to write to the cbmem console
buffer. Normally SMIs can only be debugged using some kind of serial
port (UART). By storing the SMI logs into cbmem we can debug SMIs using
`cbmem -1`. Now that these logs are available to the OS we could also
verify there were no errors in the SMI handler.
Since SMM can write to all of DRAM, we can't trust any pointers
provided by cbmem after the OS has booted. For this reason we store the
cbmem console pointer as part of the SMM runtime parameters. The cbmem
console is implemented as a circular buffer so it will never write
outside of this area.
BUG=b:221231786
TEST=Boot non-serial FW with DEBUG_SMI and verified SMI messages are
visible when running `cbmem -1`. Perform a suspend/resume cycle and
verify new SMI events are written to the cbmem console log.

cpu/x86/lapic: Move LAPIC configuration to MP init
The call to disable_lapic() got removed and with asus/p2b

The combination of entering SeaBIOS payload with an

This reverts commit ceaf959678905f44a54a116f37bd15acab5d4608.
The AMD Picasso SoC doesn't support x2APIC and neither advertises the
presence of its support via bit 21 in EAX of CPUID leaf 1 nor has the
bit 10 in the APIC base address MSR 0x1b set, but it does have 0xd CPUID
leaves, so just checking for the presence of that CPUID leaf isn't
sufficient to be sure that EDX of the CPUID leaf 0xb will contain a
valid APIC ID.
In the case of Picasso EDX of the CPUID leaf 0xb returns 0 for all cores
which causes coreboot to get stuck somewhere at the end of MP init.
I'm not 100% sure if we should additionally check bit 21 in EAX of CPUID
function 1 is set instead of adding back the is_x2apic_mode check.
TEST=Mandolin with a Picasso SoC boots again.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

In PARALLEL_MP case enable_lapic() was redundant as it
