Vladimir Serbinenko 2657e84109 Multiboot: remove multiboot tables generation.
GRUB2-as-payload doesn't use them. Libpayload can live with just coreboot tables
if loaded as payload. memtest86+ can use them but is buggy with them. Solaris
needs a huge boot archive not supported by coreboot and too big to fit in
flash (dozens of megabytes). All-in-all looks like no users are left for this.

Alexandru Gagniuc 2c38f50b4a cpu/intel: Make all Intel CPUs load microcode from CBFS
The sequence to inject microcode updates is virtually the same for all
Intel CPUs. The same function is used to inject the update in both CBFS
and hardcoded cases, and in both of these cases, the microcode resides in
the ROM. This should be a safe change across the board.

The function which loaded compiled-in microcode is also removed here in
order to prevent it from being used in the future.

The dummy terminators from microcode need to be removed if this change is
to work when generating microcode from several microcode_blob.c files, as
is the case for older socketed CPUs. Removal of dummy terminators is done
in a subsequent patch.

Kyösti Mälkki 107f72e674 Re-declare CACHE_ROM_SIZE as aligned ROM_SIZE for MTRR
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.

Duncan Laurie 911cedff97 lynxpoint: Route all USB ports to XHCI in finalize step
This commit adds a new Kconfig option for the LynxPoint
southbridge that will have coreboot route all of the USB
ports to the XHCI controller in the finalize step (i.e.
after the bootloader) and disable the EHCI controller(s).

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
that booting from USB still works.

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.

Duncan Laurie cb73a8410c Clean up POST codes for Boot State machine
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.

interrupted boot with reset button and
gathered the eventlog.  Mosys has been extended to
decode the well-known POST codes:

27 | 2013-06-10 10:32:48 | Last post code in previous boot | 0x75 | Device Initialize

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.

Marc Jones 2a58ecde78 Add new finalize functions for devices and chips
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.

not implement get_top_of_ram() to support early CBMEM.

Also remove references to globals high_tables_base and _size under
arch/ and from two ARMv7 boards.

We can postpone the call to set_top_of_ram_once() outside the

As set_top_of_ram() is now only called once, it is no longer
necessary to check if high_tables_base was already set.

Add three functions to edid.c:

void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr)
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)
returns value of the static vbe_valid.

void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
copies the static edid_fb to lb_framebuffer.

There is now a common vbe.h in src/include, removed the two special ones.

In general, graphics in coreboot is a mess, but graphics is always a
mess.  We don't have a clean way to try two different ways to turn on
a device and use the one that works. One battle at a time. Overall,
things are much better.

The best part: this code would also work for ARM, which also uses EDID.

Kyösti Mälkki fb387dfb92 usbdebug: Drop duplicates of EHCI BAR relocation code
All the additional work that needs to be done in EHCI BAR relocation
is independent of the hardware platform and was functionally identical
in all the copies removed.

When USBDEBUG is not selected, PCI EHCI controllers use standard
pci_dev_read_resources() call.

With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,
and calls the original .set_resources to configure hardware side.

Nico Huber dd4715b6a5 pnp: Implement common handling for PnP config modes
Many super i/o chips only answer to PnP requests if they are in a
configuration state (sometimes also called ext func mode). To cope with
that, the code of many chips implements its own version of our default
PnP functions like pnp_set_resource(), pnp_enable_resource() etc.

To avoid this code duplication, this patch extends our PnP device
interface with optional functions to enter and exit configuration mode.

Nico Huber f898f7ba4d pnp: Provide alternative pnp_enable() implementation
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.

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.

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.

Aaron Durbin 0748d30554 boot state: add ability to block state transitions
In order to properly sequence the boot state machine it's
important that outside code can block the transition from
one state to the next. When timers are not involved there's
no reason for any of the existing code to block a state
transition. However, if there is a timer callback that needs to
complete by a certain point in the boot sequence it is necessary
to place a block for the given state.

To that end, 4 new functions are added to provide the API for
blocking a state.
1. boot_state_block(boot_state_t state, boot_state_sequence_t seq);
2. boot_state_unblock(boot_state_t state, boot_state_sequence_t seq);
3. boot_state_current_block(void);

needed. Instead rely on the presence of a tsc_freq_mhz() function
provided by the cpu/board.  Additionally, assume that if
TSC_CONSTANT_RATE is selected the udelay() function in SMM will
be the tsc.

David Hendricks 040f25b73a timer.h: add mono_time_diff_microseconds()
The current way to get a simple mono_time difference is:
1. Declare a rela_time struct
2. Assign it the value of mono_time_diff(t1, t2)
3. Get microseconds from it using rela_time_in_microseconds().

This patch adds a simpler method. Now one only needs to call
mono_time_diff_microseconds(t1, t2) to obtain the same value which
is produced from the above three steps.

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.

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.

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().

David Hendricks cfb73607be replace device/i2c.h with simpler version
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.

variable range MTRR index to use to perform the caching enablement.

An example usage implementation would be to obtain the variable MTRR
index that covers the ROM from the coreboot tables. Then one would
disable caching and change the MTRR type from uncacheable to
write-protect and enable caching. The opposite sequence is required
to tearn down the caching.

Aaron Durbin 77a5b4046a x86: mtrr: add CONFIG_CACHE_ROM support
The CONFIG_CACHE_ROM support in the MTRR code allocates an MTRR
specifically for setting up write-protect cachine of the ROM. It is
assumed that CONFIG_ROM_SIZE is the size of the ROM and the whole
area should be cached just under 4GiB. If enabled, the MTRR code
will allocate but not enable rom caching. It is up to the callers
of the MTRR code to explicitly enable (and disable afterwards) through
the use of 2 new functions:
- x86_mtrr_enable_rom_caching()
- x86_mtrr_disable_rom_caching()

Additionally, the CACHE_ROM option is exposed to the config menu so
that it is not just selected by the chipset or board. The reasoning
is that through a multitude of options CACHE_ROM may not be appropriate
for enabling.

Aaron Durbin a05a8522ce lib: add memrange infrastructure
The memrange infrastructure allows for keeping track of the
machine's physical address space. Each memory_range entry in
a memory_ranges structure can be tagged with an arbitrary value.
It supports merging and deleting ranges as well as filling in
holes in the address space with a particular tag.

The memrange infrastructure will serve as a shared implementation
for address tracking by the MTRR and coreboot mem table code.

Aaron Durbin 3ece5ac40c stdlib: add ALIGN_UP and ALIGN_DOWN macros
There wasn't an equivalent to align down so add ALIGN_DOWN.
For symmetry provide an ALIGN_UP macro as well.
