1455437c9e x86: Add Kconfig to disable early bootblock postcodes
The Intel cave creek chipset needs to have port 80 routing configured
before any post codes can be sent to port 80h.  Sending post codes out
before the routing is done will hang the system.

This patch allows us to disable the first couple of post codes that go
out before the routing can be configured.

The Kconfig symbol is selected by the cave creek chipset (fsp_i89xx).

75c51d9af1 x86: add standalone verstage support
To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

3a54318856 Add EM100 'hyper term' spi console support in ramstage & smm
The EM100Pro allows the debug console to be sent over the SPI bus.
This is not yet working in romstage due to the use of static variables
in the SPI driver code.  It is also not working on chipsets that have
SPI write buffers of less than 10 characters due to the 9 byte
command/header length specified by the EM100 protocol.

While this currently works only with the EM100, it seems like it would
be useful on any logic analyzer with SPI debug - just filter on command
bytes of 0x11.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

90f6cd3567 Add console wrapper for UART driver
Coreboot is designed to have a single serial console at most, on top
of that it may have a CBMEM (virtual) console. Matters are complicated
by the fact that console interface is different between bootblock and
later stages.

A linker list of console driver descriptors is used to allow to
determine the set and type of console drivers at compile time. Even
though the upstream seems to have done away with this approach, which
does not seem the best idea.

As an alternative this patch introduces a common wrapper which
different UART drivers can plug in into. The driver exports a single
API which can be used both directly (in bootblock) and through the
wrapper (in later stages).

The existing drivers can be adjusted to fit this scheme one by one.
The common UART driver API also aligns fine with the upstream
approach.

ec5e5e0db2 New mechanism to define SRAM/memory map with automatic bounds checking
This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.

The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).

BUG=None

60ef456f46 console/Kconfig: Enable CBMEM console by default
Currently on AMD boards no romstage messages can be saved in CBMEM, so
only messages from ramstage on will be stored in CBMEM. Other than
that nothing changes.

Enabling CBMEM console by default does not noticeably decrease boot
time as the messages are directly written to CAR or RAM.

The board status script under `util/board_status/` reads the coreboot
messages from CBMEM, which are then uploaded to the board status
repository. With CBMEM console disabled by default, currently no
coreboot console messages are uploaded to the board status repository,
although it is important to have those.

Enabling CBMEM console by default improves this situation, so that for
all boards at least ramstage messages are stored in the board status
repository.

a63719407f x86 cache-as-ram: Remove BROKEN_CAR_MIGRATE option
This was added to handle cases of Intel FSP platforms that had
EARLY_CBMEM_INIT but could not migrate CAR variables to CBMEM.
These boards were recently fixed.

To support combination of EARLY_CBMEM_INIT without CAR migration was
added maintenance effort with little benefits. You had no CBMEM
console for romstage and the few timestamps you could store were
circulated via PCI scratchpads or CMOS nvram.

8659e4072e CBMEM console: Fix and enhance pre-RAM support
Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can
do CBMEM console in bootblock and romstage. Kconfig forces it to zero
if _BASE is unset or we cannot do CAR migration on x86.

Add CBMEM console to bootblock, except for x86. Only one of bootblock
and romstage clears the pre-RAM buffer.

To start with empty console log on S3 wakeup, ramstage now clears
previous contents of CBMEM buffer if there was no pre-RAM buffer.

Unify Kconfig variable naming.

TODO: ARM configurations do not define PRERAM_BUFFER_BASE values.

d6865222c8 misc: Drop print_ implementation from non-romcc boards
Because we had no stack on romcc boards, we had a separate, not as
powerful clone of printk: print_*.

Back in the day, like more than half a decade ago, we migrated a lot
of boards to printk, but we never cleaned up the existing code to be
consistent. Instead, we worked around the problem with a very messy
console.h (nowadays the mess is hidden in romstage_console.c and
early_print.h)

This patch cleans up the generic code pieces to use printk() on all
non-ROMCC boards.

Our two remaining ROMCC boards are fixed up in this commit:
bifferos/bifferboard and dmp/vortex86ex.

35382a6eeb cbmem console: Locate the preram console with a symbol instead of a section.
On non-x86 systems, the location of the preram CBMEM console may not be in a
predictable place relative to other things in the linker script. That makes it
difficult to work with as its own section because the linker will complain if
you try to move backwards as it lays out memory. If the console header is
treated as an actual blob of memory which has to be put in the image, we'd
have to predict where to put it so that it isn't before something with a lower
address or after something with a higher address. Symbols, on the other hand,
can be defined arbitrarily.

d84afd3e61 arm: Remove CAR_MIGRATE Kconfig and associated cruft
This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
mechanism is only useful to migrate variables from a special region
(e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
the romstage (it does not persist into ramstage). Since ARM devices use
SRAM for which there is no reason to become inaccessible in later parts
of the romstage, this mechanism isn't useful for them. Removing it makes
the romstage.ld script much simpler, which has the nice side-effect of
putting the BSS at the end of the memory image (so that cbfstool can
actually figure out that it doesn't need to be part of the ROM image).

51edd54738 ARM: Generalize armv7 as arm.
There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

ad488d25b0 src/console/Kconfig: Fix choice for showing POST codes on console
Use CONSOLE_POST because the preprocessor conditional in post_code()
in src/console/post.c depends on it, while POST_IO is used in another
conditional for sending the codes to an I/O port.

fd95624dae console: Drop driver list in ramstage
This framework was only available in ramstage. So we had to define
console output functions separately for bootblock, romstage and SMM.
Follow-up patches will re-enable all the consoles removed here,
in a more flexible fashion, and with less lines-of-code and copy-paste.

Also the driver list is not in a well-defined order and some of the
loops could exit without visiting all drivers.

NOTE: This build has no console in ramstage.

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.

interrupted boot with reset button and
gathered the eventlog after several test runs:

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.

038aa29dc2 console: add support for QEMU's debugcon
Add support for sending debug output to an I/O port.

It can be used together with QEMU's isa-debugcon driver to log the
coreboot output to a file.  The port is configurable and defaults
to 0x402 which has established as the de facto standard. For example,
SeaBIOS+OVMF [1] use that one too.

711a6fde0d Get rid of MAXIMUM_CONSOLE_LOGLEVEL; compile all messages into the coreboot binary
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.

79e36d9060 Improve how our printk calls do_div by using constants.
The do_div code has a nice optimization in it when it is called with
constants. The current highly generalized use of it defeats those
optimizations and causes trouble on ARM, resulting in a complex and
buggy code path.

Since we only need to print in bases 8, 10, and 16, do a minor
restructuring of the code so that we call do_div with constants.
If you need base 2, print in base 16 and do it in your head. :-)

This fixes an ongoing problem with ARM, will not harm X86, and will
help PPC should we ever want to support it again.
Plus, I don't have to ever try to understand the div64 assembly and where
it's going wrong :-)

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.

Some mainboards have really nice capabilities for posting, beyond
simple POST cards. Further, some can not use a POST card. This
change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.

If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:

void mainboard_post(u8 value)
{
	switch(value){
		case POST_TIME_TO_PARTY: some_fancy_lights();
		break;
	}
}

Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

BUG=None

32da8bed19 CBMEM CONSOLE: Add CBMEM console driver implementation.
The CBMEM console driver saves console output in a CBMEM area, which
then is made available to Linux applications for perusing.

There are some system limitations which need to be worked around
to achieve this goal:

- some console traffic is generated before DRAM is initialized,
  leave alone CBMEM initialized.

- after the RAM based stage starts, a lot of traffic is generated
  before CBMEM is initialized.

As a result, the console log lives in three different places -
the bottom of the cache as RAM space, the CBMEM buffer (where it
is expected to be) and a static buffer used early in the RAM
stage.

When execution starts (in the cache as RAM mode), the console
buffer is allocated at the bottom of the cache as RAM memory
address range. Once DRAM is initialized, the CBMEM structure is
initialized, and then the console buffer contents are copied from
the bottom of the cache as RAM space into the CBMEM area right
before the cache as RAM mode is disabled. The
src/lib/cbmem_console.c:cbmemc_reinit() takes care of the
copying.

At this point the cache as RAM memory is about to be disabled,
but the ROM stage is still going generating console output. To
make sure this output is not lost, cbmemc_reinit() saves the new
buffer address at a fixed location (0x600 was chosen for this),
and the actual "printing" function checks to see if the RAM is
already initialized (the stack is in RAM), and if so, gets the
console buffer pointer from this location instead of using the
cache as RAM address.

When the RAM stage starts, a static buffer is used to store the
console output, as the CBMEM buffer location is not known. Then,
when CBMEM is reinitialized, cbmemc_reinit() again takes care of
the copying.

In case the allocated buffers are not large enough, the excessive
data is dropped, and the copying routine adds some text to the
output buffer to indicate that there has been data lost and how
many characters were dropped.

a68555f48d Do full flush on uart8250 only at end of printk.
The previous code does a full flush of the uart after every character.
Unfortunately, this can cause transmission delays on some serial
ports.

This patch changes the code so that it does a flush at the end of
every printk instead of at the end of every character.  This reduces
the time it takes to transmit serial messages (up to 9% on my Asrock
e350m1 board).  It also makes the transmission time more consistent
which is important when performing timing tests via serial
transmissions.

5a1f597085 This patch drops arch/i386/lib/console.c and arch/i386/lib/console_print.c and
makes include/console/console.h and console/console.c usable both in
__PRE_RAM__ and coreboot_ram stages.

While debugging this, I removed an indirection from the e7520 ram init code
(same as we did on a couple of other chipsets, removes some register pressure
  from romcc)

Also, drop remainders of CONFIG_USE_INIT (except the one odd piece of dead code 
		in cache_as_ram.inc)

Then some ap_romstage.c fixes, at least the nvidia/l1_2pvv compiled for me with
CONFIG_AP_CODE_IN_CAR set in Kconfig which it did not before.

5f0aefbef5 SMM: remove hack that was needed back in oldconfig times.
These days it even does the wrong thing (not using the .smmobj.o version of
vtxprintf.c and printk.c)
Also, SMM never needed libgcc, it's only in coreboot_ram for yabel/x86emu's
crazy math.

68a564f7ac This patch is what I needed to compile coreboot with LLVM.
- call va_* directly if coreboot is running on GCC so we don't need 
  to maintain hacks to get to stdarg.h
- only define LIBGCC_FILE_NAME if it's an absolute path. GCC and LLVM
  just print "libgcc.a" if the file is not there.

01ce601bdb This patch is from 2009-10-20
Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and
local #defines into globally configurable kconfig options (and Options.lb
options for as long as newconfig still exists) which can be enabled
by the user in the "Debugging" menu.

The respective menu items only appear if a board is selected where the
chipset code actually provides such additional DEBUG output.

All three variables default to 0 / off for now.

Also, drop a small chunk of dead/useless code in the
src/northbridge/via/cn700/raminit.c file, which would otherwise break
compilation.

- Add static and const where possible.

 - Turn some #warning entries into TODO comments.

 - Add missing prototypes.

 - Remove unused variables.

 - Fix printf arguments or cast them as needed.

 - Make sconfig output look better. Drop useless "PARSED THE TREE" output.

 - Print "(this may take a while)" while building romcc. Add missing "\n".
