Stefan Reinauer 802c910fa3 Increase space for ACPI tables when using dynamic CBMEM
Unlike in old style CBMEM, dynamic CBMEM does not have a 
hand-calculated, hard-coded size, so allow up to 144K of
space for ACPI tables.

Furquan Shaikh 133096b6dc coreboot classes: Add dynamic classes to coreboot
Provide functionality to create dynamic classes based on program name and
architecture for which the program needs to be compiled/linked. define_class
takes program_name and arch as its arguments and adds the program_name to
classes-y to create dynamic class. Also, compiler toolset is created for the
specified arch. All the files for this program can then be added to
program_name-y += .. Ensure that define_class is called before any files are
added to the class. Check subdirs-y for order of directory inclusion.

One such example of dynamic class is rmodules. Multiple rmodules can be used
which need to be compiled for different architectures. With dynamic classes,
this is possible.

Edward O'Callaghan b0195a3325 build: Pass correct disassembly flags in Clang build
On SVR4-derived platforms, the character `/' is treated as a comment
character, which means that it cannot be used in expressions. The
`--divide' option turns `/' into a normal character. This seems to be
needed with our local build of binutils since we don't yet use the
internal assembler/disassembler of the Clang tooling.

Mike Loptien d0167d3ae2 MP Spec: Correct the Virtual Wire assignment
Virtual Wire mode is set by writing 0 to the the MPTable
Feature2 bit field 'IMCR'.  The virtualwire variable was
initially defined as writing a 1 to this bit field which
would actually set PIC mode instead of Virtual Wire mode.
However, nearly every mainboard called the MPTables with
virtualwire = 0, which actually had the effect of setting
Virtual Wire mode. I am correcting the definition but
leaving the call to write the MPTables with virtualwire = 0,
which is how most mainboards are already setting the tables
up.

See the MP Spec table 4-1 for more details:
	Bit 7: IMCRP. When the IMCR presence bit is
	set, the IMCR is present and PIC Mode is
	implemented; otherwise, Virtual Wire Mode is
	implemented.

Furquan Shaikh 99ac98f7e1 Introduce stage-specific architecture for coreboot
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.

These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.

In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.

Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.

We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.

To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

Patrick Georgi df29f1ba6f CAR_GLOBAL: Define section details once
Improve clang compatibility by dropping an opaque hack

The section attribute was only ever meant for specifying
section names, not their properties - otherwise they would
have provided section(name,attribute,class) instead of only
section(name).

The hack to add attribute and class to the name, and commenting
out the "real" definitions inserted by the compiler (see the
terminating "#"), is refused by clang developers.

This is a cleaner implementation in that the section is first
declared with its properties, then used later-on, expecting that
later conflicting declarations are ignored.

It can still break in two ways:
1. The assembler or linker could complain about a section declared
in two different ways.
2. The assembler could just use the latest declaration, not the first,
to determine the section's properties.

I won't sort these out unless they actually happen.

Alexandru Gagniuc 299c265102 Refactor usage of walkcbfs to permit access to CBFS headers
walkcbfs() is used only with ROMCC. Besides finding stages during the
bootblock, it's also used when applying microcode updates during the
bootblock phase. The function used to return only a pointer to the data of
the CBFS file, while making the header completely inaccessible. Since the
header contains the length of the CBFS file, the caller did not have a way
to know how long the data was. Then, other conventions had to be used to
determine the EOF, which might present problems if the user replaces the
CBFS file. This is not an issue when jumping to a stage (romstage), but can
present problems when accessing a microcode file which has not been
NULL-terminated.

Refactor walkcbfs_asm to return a pointer to the CBFS file header rather
than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new
walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs()
remains unaffected.
The code has been verified to run successfully under qemu.

Subsequent patches will change usage of walkcbfs() to walkcbfs_head where
knowing the length of the data is needed.

included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or
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.

Duncan Laurie 8adf7a2c50 Log device path into CMOS during probe stages
One of the most common hangs during coreboot execution
is during ramstage device init steps.  Currently there
are a set of (somewhat misleading) post codes during this
phase which give some indication as to where execution
stopped, but it provides no information on what device
was actually being initialized at that point.

This uses the new CMOS "extra" log banks to store the
encoded device path of the device that is about to be
touched by coreboot.  This way if the system hangs when
talking to the device there will be some indication where
to investigate next.

integrating it into coreboot’s build system, so it can be selected in
Kconfig.

As the last GRUB 2 release 2.00 is too old and has several bugs when
used as a coreboot payload only allow to build GRUB 2 master until a new
GRUB release is done. The downside is, that accidental breakage in
GRUB’s upstream does not affect coreboot users.

Currently the GRUB 2 payload is built with the default modules which
results in an uncompressed size of around 730 kB. Compressed it has a
size of 340 kB, so it should be useable with 512 kB flash ROMs.

Tested with QEMU.

Kyösti Mälkki 082c19ea89 CBMEM: Fail builds on missing get_top_of_ram()
Dummy get_top_of_ram() is removed from romstage to fail already at
build-time for cases where cbmem_initialize() would not complete.

The mechanisms behind CAR_GLOBAL migration only work correctly when
romstage can succesfully make the cbmem_initialize() call.

This reverts commit de1fe7f655.

While things appeared to work, there were actually invalid references
to CAR storage after CAR was torn down on boards without
EARLY_CBMEM_INIT. It was discussed use of CAR_GLOBAL should be
restricted to boards that handle CAR migration properly.

If romstage does not make cbmem_initialize() call, linker should
optimize the code for CAR migration away.

As console buffer is now migrated within cbmem_initialize() call there

Gerd Hoffmann cbf30736b6 qemu: add x86 cpu
This patch adds a qemu x86 cpu chip.  It has no initialization function
as this isn't needed on virtual hardware.  A virtual machine can have
pretty much any CPU: qemu emulates a wide range of x86 CPUs (try 'qemu
-cpu ? for a list), also with 'qemu -cpu host' the guest will see a cpu
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.

Ronald G. Minnich a296ce75e3 Move the MARK_GRAPHICS_MEM_WRCOMB to x86 architecture
The MARK_GRAPHICS_MEM_WRCOMB was spreading like a cancer
since it was defined in sandybridge. It is really
more of an x86 thing however, and we now have
three systems that can use it.

I considered making this more general, since it technically
can apply to PTE-based systems like ARM, and maybe we should.
But the 'WRCOMB' moniker is usually closely tied to the x86.

Aaron Durbin 716738a6b8 x86: add cache-as-ram migration option
There are some boards that do a significant amount of
work after cache-as-ram is torn down but before ramstage
is loaded. For example, using vboot to verify the ramstage
is one such operation. However, there are pieces of code
that are executed that reference global variables that
are linked in the cache-as-ram region. If those variables
are referenced after cache-as-ram is torn down then the
values observed will most likely be incorrect.

Therefore provide a Kconfig option to select cache-as-ram
migration to memory using cbmem. This option is named
CAR_MIGRATION. When enabled, the address of cache-as-ram
variables may be obtained dynamically. Additionally,
when cache-as-ram migration occurs the cache-as-ram
data region for global variables is copied into cbmem.
There are also automatic callbacks for other modules
to perform their own migration, if necessary.

Aaron Durbin 4409a5eef6 coreboot: add thread cooperative multitasking
The cooperative multitasking support allows the boot state machine
to be ran cooperatively with other threads of work. The main thread
still continues to run the boot state machine
(src/lib/hardwaremain.c).  All callbacks from the state machine are
still ran synchronously from within the main thread's context.
Without any other code added the only change to the boot sequence
when cooperative multitasking is enabled is the queueing of an idlle
thread. The idle thread is responsible for ensuring progress is made
by calling timer callbacks.

The main thread can yield to any other threads in the system. That
means that anyone that spins up a thread must ensure no shared
resources are used from 2 or more execution contexts. The support
is originally intentioned to allow for long work itesm with busy
loops to occur in parallel during a boot.

Note that the intention on when to yield a thread will be on
calls to udelay().

            printk(BIOS_SPEW, " 0x%08x\n", reg32);
    }

Add similar code to `src/arch/x86/lib/ioapic.c` so all boards using
the function `set_ioapic_id()` get the debug feature and the other
boards can be more easily adapted in follow-up patches.

Aaron Durbin bebf66909a x86: use boot state callbacks to disable rom cache
On x86 systems there is a concept of cachings the ROM. However,
the typical policy is that the boot cpu is the only one with
it enabled. In order to ensure the MTRRs are the same across cores
the rom cache needs to be disabled prior to OS resume or boot handoff.
Therefore, utilize the boot state callbacks to schedule the disabling
of the ROM cache at the ramstage exit points.
