The PCI Specification states that devices that implement
a bridge and a secondary bus must swizzle (rotate) the
interrupt pins according to the table below:
Child Dev # Child PIN Parent PIN
0,4,8,12... A/B/C/D A/B/C/D
1,5,9,13... A/B/C/D B/C/D/A
2,6,10,14.. A/B/C/D C/D/A/B
3,7,11,15.. A/B/C/D D/A/B/C
Which is also described by this equation:
PIN_parent = (Pin_child + Dev_child) % 4
When a device is found and its bus number is greater than 0,
it is on a bridge and needs to be swizzled. Following the
string of parents up to the root bus and swizzling as we go
gives us the desired swizzling result. When BIOS_SPEW is
defined, it will print out each step of the swizzling process.

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.

Start using the rmodtool for generating rmodules.
rmodule_link() has been changed to create 2 rules:
one for the passed in <name>, the other for creating
<name>.rmod which is an ELF file in the format of
an rmodule.
Since the header is not compiled and linked together
with an rmodule there needs to be a way of marking
which symbol is the entry point. __rmodule_entry is
the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an
rmodule entry point symbol takes a single argument.

Fixing the location of the ram oops buffer can lead to certain

Boot speeds can be sped up by mirroring the payload into
main memory before doing the actual loading. Systems that
would benefit from this are typically Intel ones whose SPI
are memory mapped. Without the SPI being cached all accesses
to the payload in SPI while being loaded result in uncacheable
accesses. Instead take advantage of the on-board SPI controller
which has an internal cache and prefetcher by copying 64-byte
cachelines using 32-bit word copies.

With the recent improvement 3d6ffe76f8,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly

Provide a common entry point for bringing up the APs
in parallel. This work is based off of the Haswell one
which can be moved over to this in the future. The APs
are brought up and have the BSP's MTRRs duplicated in
their own MTRRs. Additionally, Microcode is loaded before
enabling caching. However, the current microcode loading
support assumes Intel's mechanism.
The infrastructure provides a notion of a flight plan
for the BSP and APs. This allows for flexibility in the
order of operations for a given architecture/chip without
providing any specific policy. Therefore, the chipset
caller can provide the order that is required.

The function which loaded compiled-in microcode is also removed here in

The dummy terminators from microcode need to be removed if this change is

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

ports to the XHCI controller in the finalize step (i.e.

Additionally when doing this the XHCI USB3 ports need
to be put into an expected state on resume in order to make
the kernel state machine happy.
Part of this could also be done in depthcharge but there
are also some resume-time steps required so it makes sense
to keep it all together in coreboot.
This can theoretically save ~100mW at runtime.
Verify that the EHCI controller is not found in Linux and

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.

Now that there is a clearly defined boot state machine
we can add some useful post codes to indicate the current
point in the state machine by having it log a post code
before the execution of each state.
This removes the currently defined POST codes that were
used by hardwaremain in favor of a new contiguous range
that are defined for each boot state.
The reason for this is that the existing codes are mostly
used to indicate when something is done, which is confusing
for actual debug because POST code debugging relies on knowing
what is about to happen (to know what may be at fault) rather
than what has just finished.
One additonal change is added during device init step as this
step often does the bulk of the work, and frequently logs POST
codes itself. Therefore in order to keep better track of what
device is being initialized POST_BS_DEV_INIT is logged before
each device is initialized.

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.

Many chipset devices require additional configuration after
device init. It is not uncommmon for a device early in the devicetree
list to need to change a setting after a device later in the tree does
PCI init. A final function call has been added to device ops to handle
this case. It is called prior to coreboot table setup.
Another problem that is often seen is that the chipset or mainboard
need to do some final cleanup just before loading the OS. The chip
finalize has been added for this case. It is call after all coreboot
tables are setup and the payload is ready to be called.
Similar functionality could be implemented with the hardwaremain
states, but those don't fit well in the device tree function pointer
structure and should be used sparingly.

It might be that you want an early console in romstage before RAM is up, but
you can't or don't want to support the console all the way back in the
bootblock. By making the console in those two different environments
configurable seperately that becomes possible.
On the 5250 console output as early as the bootblock works, but on the 5420 it
only starts working in the ROM stage after clocks have been initialized.

takes an edid and uintptr_t, and fills in a static lb_framebuffer struct
as well as setting the static vbe_valid to 1 unless some problem
is found in the edid. The intent here is that this could be called from
the native graphics setup code on both ARM and x86.
int vbe_mode_info_valid(void)

The current default implementation of pnp_enable() only disables devices
- if set so in the devicetree - but does not enable them. Enablement takes
place in pnp_enable_resources(). Yet, many PnP chips implement their own
version of pnp_enable() which also enables devices if set in the devicetree.
It's arguable, if enabling those devices makes sense, before they get
resources assigned. Maybe we can't write the resource registers if not,
who knows? The least we can do is providing a common implementation for
this behavior, and get rid of some code duplication.

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.

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().

This option has never had much if any use. It solved a problem over 10
years ago that resulted from an argument over the value or lack thereof
of including all the debug strings in a coreboot image. The answer is
in: it's a good idea to maintain the capability to print all messages,
for many reasons.
This option is also misleading people, as in a recent discussion, to
believe that log messges are controlled at build time in a way they are
not. For the record, from this day forward, we can print messages at all
log levels and the default log level is set at boot time, as directed by
DEFAULT_CONSOLE_LOGLEVEL. You can set the default to 0 at build time and
if you are having trouble override it in CMOS and get more messages.
Besides, a quick glance shows it's always set to max (9 in this case) in
the very few cases (1) in which it is set.

The notion of a monotonic timer is introduced. Along with it
are helper functions and other types for comparing times. This
is just the framework where it is the responsibility of the
chipset/board to provide the implementation of timer_monotonic_get().
The reason structs are used instead of native types is to allow
for future changes to the data structure without chaning all the
call sites.

The notion of loading a payload in the current boot state
machine isn't actually loading the payload. The reason is
that cbfs is just walked to find the payload. The actual
loading and booting were occuring in selfboot(). Change this
balance so that loading occurs in one function and actual
booting happens in another. This allows for ample opportunity
to delay work until just before booting.

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.

Utilize the static boot state callback scheduling to initialize
and tear down the coverage infrastructure at the appropriate points.
The coverage initialization is performed at BS_PRE_DEVICE which is the
earliest point a callback can be called. The tear down occurs at the
2 exit points of ramstage: OS resume and payload boot.

It's helpful to provide a distinct state that affirmatively
describes that OS resume will occur. The previous code included
the check and the actual resuming in one function. Because of this
grouping one had to annotate the innards of the ACPI resume
path to perform specific actions before OS resume. By providing
a distinct state in the boot state machine the necessary actions
can be scheduled accordingly without modifying the ACPI code.

Many of the boot state callbacks can be scheduled at compile time.
Therefore, provide a way for a compilation unit to inform the
boot state machine when its callbacks should be called. Each C
module can export the callbacks and their scheduling requirements
without changing the shared boot flow code.

The boot flow currently has a fixed ordering. The ordering
is dictated by the device tree and on x86 the PCI device ordering
for when actions are performed. Many of the new machines and
configurations have dependencies that do not follow the device
ordering.
In order to be more flexible the concept of a boot state machine
is introduced. At the boundaries (entry and exit) of each state there
is opportunity to run callbacks. This ability allows one to schedule
actions to be performed without adding board-specific code to
the shared boot flow.

Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to
the first 128bit machines.

Add a microsecond timer, its declaration, the function to start it,
and its usage. To start it, one calls timer_start(). From that point
on, one can call timer_us() to find microseconds since the timer was
started.
We show its use in the bootblock. You want it started very early.
Finally, the delay.h change having been (ironically) delayed, we
create time.h and have it hold one declaration, for the timer_us() and
timer_start() prototype.
We feel that these two functions should become the hardware specific
functions, allowing us to finally move udelay() into src/lib where it
belongs.

siemens/sitemp_g1p1: Make ACPI report the right mmconf region
ACPI reported the entire space between top-of-memory and some
(relatively) arbitrary limit as useful for MMIO. Unfortunately
the HyperTransport configuration disagreed. Make them match up.
Other boards are not affected since they don't report any region
for that purpose at all (it seems).

This re-factors the Exynos5 I2C code to be simpler and use the
new API, and updates users accordingly.
- i2c_read() and i2c_write() functions updated to take bus number
as an argument.
- Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and
i2c_write(). If a chip needs special handling we should take care
of it elsewhere, not in every low-level i2c driver.
- All the confusing bus config functions eliminated. No more
i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this
is handled automatically when the caller does a transaction and
specifies the desired bus number.
- i2c_probe() eliminated. We're not a command-line utility.
- Let the compiler place static variables automatically. We don't need
any of this fancy manual data placement.
- Remove dead code while we're at it. This stuff was ported early on
and much of it was left commented out in case we needed it. Some
also includes nested macros which caused gcc to complain.
- Clean up #includes (no more common.h, woohoo!), replace debug() with
printk().

The existing header was imported along with the Exynos code and left
mostly unchanged. This is the first patch in a series intended to
replace the imported u-boot I2C API with a much simpler and cleaner
interface:
- We only need to expose i2c_read() and i2c_write() in our public API.
Everything else is board/chip-dependent and should remain hidden
away.
- i2c_read and i2c_write functions will take bus number as an arg
and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to
error and end up cluttering the code since the user needs to save
the old bus number, set the new one, do the read/write, and restore
the old value (3 added steps to do a simple transaction).
- Stop setting default values for board-specific things like SPD
and RTC bus numbers (as if we always have an SPD or RTC on I2C).
- Death to all the trivial inline wrappers. And in case there was any
doubt, we really don't care about the MPC8xx. Though if we did then
we would not pollute the public API with its idiosyncrasies.
