Patrick Rudolph b9959e279c cpu/intel/model_206ax: Use tsc monotonic timer
Switch from lapic to tsc.

Allows timestamps to be used in coreboot, as there's a reference
clock available to calculate correct time units.

Clean Kconfig, remove duplicated lapic code and include tsc dir for
LGA1155 boards.

Tested on Lenovo T430.

Paul Menzel a8843dee58 Use more secure HTTPS URLs for coreboot sites
The coreboot sites support HTTPS, and requests over HTTP with SSL are
also redirected. So use the more secure URLs, which also saves a
request most of the times, as nothing needs to be redirected.

Run the command below to replace all occurences.

```
$ git grep -l -E 'http://(www.|review.|)coreboot.org'

Obscure term top_of_ram is replaced:
  backup_top_of_ram -> backup_top_of_low_cacheable
  get_top_of_ram -> restore_top_of_low_cacheable

New function that always resolves to CBMEM top boundary, with
or without SMM, is named restore_cbmem_top().

maintain and free the space for spi_flash structure as required.

Kyösti Mälkki bceccec0f7 AGESA: Handle HEAP_CALLOUT_RUNTIME allocation more cleanly
This was guarded because AGESA.h only defined it starting from fam15
header files. We can simply test if it has been defined.

The way coreboot currently handles this request, is to make the
allocation outside the heap, since heap may not be in CBMEM and thus
not available runtime. The acquired buffer from Allocate() would not
be found with Locate() or Deallocate(), so move the alloc_cbmem()
call for better code symmetry.

Kyösti Mälkki 97a4b3edf0 binaryPI platforms: Drop any ACPI S3 support
No board with binaryPI currently supports HAVE_ACPI_RESUME. For
platforms with PSP the approach is also very different from what
we previously had here.

Furthermore, s3_resume.[ch] files under cpu/amd/pi do not
distinguish between NonVolatile and Volatile buffers of S3 storage.
This means the Volatile buffer that is maintained and available in
CBMEM is unnecessarily copied to SPI flash. This has been fixed on
open-source AGESA directory, so development of S3 suspend support
with binaryPI is better continued with that.

Unfortunately there are further complications and indications that
open-source AGESA may have always had a low-memory corruption
issue. This has to be investigated separately before restoring
or claiming S3 is supported on binaryPI.

Marshall Dawson 03e6a455a3 amd/pi/hudson: Move APIC enable to CPU file
Relocate the enabling of the LAPIC out of the southbridge source and
surround it with a check for CONFIG_UDELAY_LAPIC (typical for AMD
systems).  The LAPIC is now enabled for all cores; not only the BSP,
and not only when the UART is used.

This solves the problem of APs not having their APICs enabled when
the timer is expected to be functional, e.g. verstage often uses
do_printk_va_list() instead of do_printk() which exits early for
APs when CONFIG_SQUELCH_EARLY_SMP=y.

The changes were tested with two Gardenia builds, one using verstage
and another with CONFIG_SQUELCH_EARLY_SMP=n.

Damien Zammit 75a3d1fb7c amdfam10: Perform major include ".c" cleanup
Previously, all romstages for this northbridge family
would compile via 1 single C file with everything
included into the romstage.c file (!)

This patch separates the build into separate .o modules
and links them accordingly.

Currently compiles and links all fam10 roms without
breaking other roms.

Both DDR2 and DDR3 have been completed

TESTED on REACTS: passes all boot tests for 2 boards
 ASUS KGPE-D16
 ASUS KFSN4-DRE

Some extra changes were required to make it compile
otherwise there were unused functions in included "c" files.
This is because I needed to exchange CIMX
for the native southbridge routines. See in particular:
 advansus/a785e-i
 asus/m5a88-v
 avalue/eax-785e

A followup patch may be required to fix the above boards.

Having same memory region set as both WRPROT and WRBACK

we allow DCACHE_RAM_BASE to be located within CBFS in SPI
flash memory and XIP romstage is at the same location.

As SPI master by default decodes all of top 16MiB below
4GiB, initial cache-as-ram line fills may have actually
read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.

There are no reasons to have this as board-specific setting.

Furquan Shaikh c28984d9ea spi: Clean up SPI flash driver interface
RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.

New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.

spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

Aaron Durbin 2bebd7bc93 cpu/x86/mtrr: allow temporary MTRR range during coreboot
Certain platforms have a poorly performing SPI prefetcher so even if
accessing MMIO BIOS once the fetch time can be impacted. Payload
loading is one example where it can be impacted. Therefore, add the
ability for a platform to reconfigure the currently running CPU's
variable MTRR settings for the duration of coreboot's execution.

The function mtrr_use_temp_range() is added which uses the previous
MTRR solution as a basis along with a new range and type to use.
A new solution is calculated with the updated settings and the
original solution is put back prior to exiting coreboot into the OS
or payload.

Using this patch on apollolake reduced depthcharge payload loading
by 75 ms.

The datasheets "Intel® Core™ Duo Processor and Intel® Core™ Solo
Processor on 65 nm Process" mentions cpu C-states substates which can
either be attained by adding a substate hint to the MWAIT/P_LVLx request
or automatically by setting some msr bits correctly.

This just sets the same msr bits as model_6fx to enable
dynamic L2 cache, C2E and C4E acpi cpu states.

The result is that when limiting a thinkpad x60 with a yonah T2400
cpu to the acpi cpu C2 state, the idle power usage drops from 18W to
14W. When the lowest C-state is set to C4 the idle power usage seems
to remain similar.

Martin Roth 3eb65eca69 Kconfig: Add option for microcode filenames
Hardcoding the microcode filenames into the makefiles is great when
the microcode is in the blobs directory.  When the microcode isn't
posted to the blobs directory, we need some method of supplying the
microcode binary into the build.  This can of course be done manually
after the build has completed, as can be done with everything that
we're including in the ROM image.  Instead of making life hard for
everyone though, let's just add a way to specify where the microcode
rom comes from.

Aaron Durbin 4a36c4e9fc Kconfig: lay groundwork for not assuming SPI flash boot device
Almost all boards and chipsets within the codebase assume or
use SPI flash as the boot device. Therefore, provide an option
for the boards/chipsets which don't currently support SPI flash
as the boot device. The default is to assume SPI flash is the
boot device unless otherwise instructed. This falls in line
with the current assumptions, but it also allows one to
differentiate a platform desiring SPI flash support while it not
being the actual boot device.

One thing to note is that while google/daisy does boot with SPI
flash part no SPI API interfaces were ever implemented. Therefore,
mark that board as not having a SPI boot device.

Aaron Durbin a38677b664 cpu/x86/mtrr: correct variable MTRR calculation around 1MiB boundary
The fixed MTRRs cover the range [0:1MiB). While calculating the
variable MTRR usage the 1MiB boundary is checked such that
an excessive number of MTRRs aren't used because of unnatural
alignment at the low end of the physical address space. Howevever,
those checks weren't inclusive of the 1MiB boundary. As such a
variable MTRR could be used for a range which is actually covered
by the fixed MTRRs when the end address is equal to 1MiB. Likewise,
if the starting address of the range lands on the 1MiB boundary
then more variable MTRRs are calculated in order to meet natural
alignment requirements.

to cover the greatest ramstage needs, as there is no benefit
of trying to accurately match the actual need. Choose
this to be bottom 16MiB.

With RELOCATABLE_RAMSTAGE write-back cache of low ram is
only useful for bottom 1MiB of RAM as a small part of this gets used
during SMP initialisation before proper MTRR setup.

Lee Leahy 6ec72c9b4f drivers/uart: Use uart_platform_refclk for all UART models
Allow the platform to override the input clock for the UART by
implementing the routine uart_platform_refclk and setting the Kconfig
value UART_OVERRIDE_REFCLK.  Provide a default uart_platform_refclk
routine which is disabled when UART_OVERRIDE_REFCLK is selected.  This
works around ROMCC not supporting weak routines.

Testing on Galileo:
*  Edit the src/mainboard/intel/galileo/Makefile.inc file:
   *  Add "select ADD_FSP_PDAT_FILE"
   *  Add "select ADD_FSP_RAW_BIN"
   *  Add "select ADD_RMU_FILE"
*  Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
*  Place the pdat.bin files in the location specified by
   CONFIG_FSP_PDAT_FILE
*  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
*  Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
   UEFIPAYLOAD.fd
*  Testing is successful when CorebootPayloadPkg is able to properly
   initialize the serial port without using built-in values.

Previously, the XIP_ROM_SIZE Kconfig variable is used globally on
x86 platforms with the assumption that all chipsets utilize this
value.  For the chipsets which do not use the variable it can lead
to unnecessary alignment constraints in cbfs for romstage.  Therefore,
allow those chipsets a path to not be burdened by not passing
'-P $(XIP_ROM_SIZE)' to cbfstool when adding romstage.

Aaron Durbin 82501922b6 cpu/x86: combine multiprocessor and SMM initialization
In order to reduce code duplication provide a common flow
through callback functions that performs the multiprocessor
and optionally SMM initialization. The existing MP flight
records are utilized but a common flow is provided such
that the chipset/cpu only needs to provide a mp_ops
structure which has callbacks to gather info and provide
hooks at certain points in the sequence.

All current users of the MP code can be switched over to
this flow since there haven't been any flight records that
are overly complicated and long. After the conversion
has taken place most of the surface area of the MP
API can be hidden away within the compilation unit proper.

Aaron Durbin 7f8afe0631 arch/x86: introduce postcar stage/phase
Certain chipsets don't have a memory-mapped boot media
so their code execution for stages prior to DRAM initialization
is backed by SRAM or cache-as-ram. The postcar stage/phase
handles the cache-as-ram situation where in order to tear down
cache-as-ram one needs to be executing out of a backing
store that isn't transient. By current definition, cache-as-ram
is volatile and tearing it down leads to its contents disappearing.
Therefore provide a shim layer, postcar, that's loaded into
memory and executed which does 2 things:

1. Tears down cache-as-ram with a chipset helper function.
2. Loads and runs ramstage.

Because those 2 things are executed out of ram there's no issue
of the code's backing store while executing the code that
tears down cache-as-ram. The current implementation makes no
assumption regarding cacheability of the DRAM itself. If the
chipset code wishes to cache DRAM for loading of the postcar
stage/phase then it's also up to the chipset to handle any
coherency issues pertaining to cache-as-ram destruction.

1. Only using walkcbfs when ROMCC is defined.
2. Only using spinlocks if !__PRE_RAM__

AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030]

Decoding the faulting address:

              33        SysMgtCmd (System Management Command) = 0x33

               3        SMAF (System Management Action Field) = [3:1] = 0x1
               1        Signal State Bit Map = [0] = 0x1

Therefore, the error appears to be triggered by an upstream C1E request.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by
multiple APs during startup.  Calls to the nvram read functions get_option and read_option
call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash
controller, thus placing the SP5100 in an invalid state.  This limitation is not documented
in any public AMD errata, and was only discovered through considerable debugging effort.

Damien Zammit 149c4c5d01 x86/smm: Initialize SMM on some CPUs one-by-one
We currently race in SMM init on Atom 230 (and potentially
other CPUs). At least on the 230, this leads to a hang on
RSM, likely because both hyperthreads mess around with
SMBASE and other SMM state variables in parallel without
coordination. The same behaviour occurs with Atom D5xx.

Change it so first APs are spun up and sent to sleep, then
BSP initializes SMM, then every CPU, one after another.

Timothy Pearson f8549e88e2 cpu/amd/fam10h-15h: Fix link type detection and XCS buffer count setup
The existing code did not properly detect various link attributes
on Family 10h/15h processors.  With the addition of new HT3- and
IOMMU-specific code, proper detection has become critical to avoid
system deadlocks.

Fix and streamline link attribute detection.

Ben Gardner e597e63e49 FSP 1.0: Fix CAR issues - broken timestamps and console
FSP 1.0 has a fixed-size temporary cache size and address and the entire
cache is migrated in the FSP FspInitEntry() function.

Previous code expected the symbol _car_data_start to be the same as
CONFIG_DCACHE_RAM_BASE and _car_data_end to be the same as
_preram_cbmem_console.

FSP 1.0 is the only one that migrates _preram_cbmem_console.
Others leave that where it is and extract the early console data in
cbmemc_reinit(). Special handling is needed to handle that.

Commit dd6fa93d broke both assumptions and so broke the timestamp table
and console.

The fix is to use CONFIG_DCACHE_RAM_BASE when calculating the offset and
to use _preram_cbmem_console instead of _car_data_end for the console
check.
