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.

Martin Roth 4c502697ee cpu: Add a way to use microcode .h files back to the build
The build was changed to remove usage of microcode .h files when
all of the .h files were converted to binary.  This is still
needed for some builds when microcode binaries aren't in the
blobs tree.

Timothy Pearson 855fc1fcdb cpu/microcode: Remove EXTERNAL / ADDED_DURING_BUILD variables
There has been a concerted effort to clean up coreboot's microcode
handling that has included a move away from coreboot-specific
microcode file collections.  As a result, the ability to specify
a single microcode file to be added to the image is of less utility
than before.

NOTE: This patch remove the built-in external microcode feature,
however the user can still specify no microcode during build and
manually add the correct microcode file(s) to the CBFS image after
the build is complete.

Alexandru Gagniuc a406119e9b arch/x86: Do not run UPDATE-FIT if we don't include microcode
The original intention was to only run UPDATE_FIT when a microcode file was

CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that
CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on
hasswell, the UPDATE-FIT step was always run, even when no microcode was
included, generating a build error.

Instead, introduce a new variable which tells if a microcode update is
added in CBFS during the build.

Alexandru Gagniuc f589909b91 cpu: Remove BOARD_MICROCODE_CBFS_GENERATE Kconfig option
Commit * bdafcfa Add the Intel FSP 206ax CPU core support
Introduced this option. This option was meant to have a board generate
a CBFS file containing microcode. However, microcode generation used to be
enabled by default when CPU_MICROCODE_IN_CBFS was selected.

The introduction of BOARD_MICROCODE_CBFS_GENERATE killed that automatic
default, which is not what we want. This option is misguided in the sense
that it tends to introduce a non-default which had been intentionally a
default. We now have to select two Kconfig options in order to generate
microcode in CBFS, meaning one option is redundant.

which is (almost) identical to the one on the host machine.  So I've
added X86_VENDOR_ANY as wildcard match for the cpu_table.

David Hendricks 6a503b6a0f make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.

This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.

The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.

uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

implementation). Since this is an SoC we'll forego the x86-style
{north,south}bridge and cpu distinction. We may try to split some
stuff out before the final version if prudent.

Patrick Georgi bbc880eee7 amdk8/amdfam10: Use CAR_GLOBAL for sysinfo
This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).

Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.

For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
  - from CAR setup (no need to reserve the space)
  - commented out code (that was commented out for years)
  - only copy sizeof(sysinfo) into RAM after ram init, where
    before it copied the whole GLOBAL_VAR area.
  - from Kconfig

Alexandru Gagniuc 00b579a447 buildsystem: Make CPU microcode updating more configurable
This patch aims to improve the microcode in CBFS handling that was
brought by the last patches from Stefan and the Chromium team.

Choices in Kconfig
  - 1) Generate microcode from tree (default)
  - 2) Include external microcode file
  - 3) Do not put microcode in CBFS

The idea is to give the user full control over including non-free
blobs in the final ROM image.

MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode
is handled by a special class, cpu_microcode, as such:

cpu_microcode-y += microcode_file.c

MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is
needed by intel microcode updating. Once all intel cpus are converted to
cbfs updating, this variable can go away.

These files are then compiled and assembled into a binary CBFS file.
The advantage of doing it this way versus the current method is that
  1) The rule is CPU-agnostic
  2) Gives user more control over if and how to include microcode blobs
  3) The rules for building the microcode binary are kept in
   src/cpu/Makefile.inc, and thus would not clobber the other makefiles,
   which are already overloaded and very difficult to navigate.

Stefan Reinauer 2c41c4027f Drop CONFIG_MAX_PHYSICAL_CPUS on non-AMD boards
CONFIG_MAX_PHYSICAL_CPUS is defined by quite a number of
mainboards whithout any code actually using the variable.
Hence, drop MAX_PHYSICAL_CPUS from Kconfig for those boards.

In the long run we should drop CONFIG_MAX_PHYSICAL_CPUS use
completely and make the code dynamic or depend on CONFIG_MAX_CPUS
instead.

Kyösti Mälkki 7dfe32c540 Add support for RAM-less multi-processor init
For a hyper-threading processor, enabling cache requires that both the
BSP and AP CPU clear CR0.CD (Cache Disable) bit. For a Cache-As-Ram
implementation, partial multi-processor initialisation precedes
raminit and AP CPUs' 16bit entry must be run from ROM.

The AP CPU can only start execute real-mode code at a 4kB aligned
address below 1MB. The protected mode entry code for AP is identical
with the BSP code, which is already located at the top of bootblock.
This patch takes the simplest approach and aligns the bootblock
16 bit entry at highest possible 4kB boundary below 1MB.

The symbol ap_sipi_vector is tested to match CONFIG_AP_SIPI_VECTOR
used by the CAR code in romstage. Adress is not expected to ever
change, but if it does, link will fail.
