Dependency tracking in incremental builds is currently broken for the
ramstage, due to the intermediate linking step into one ramstage.o file
per directory. The original xxx.ramstage.o files are removed from
ramstage-objs, so they don't end up in allobjs and won't get translated
into DEPENDENCIES. This patch explicitly adds them to DEPENDENCIES
beforehand to resolve the issue.
BRANCH=None
BUG=None
TEST=Built, ran 'touch src/include/cbmem.h' and built again
incrementally. Confirmed that objects dependent on the modified header
such as timestamp.ramstage.o get rebuilt correctly.

Some projects (like ChromeOS) put more content than described by CBFS
onto their image. For top-aligned images (read: x86), this has
traditionally been achieved with a CBFS_SIZE Kconfig (which denotes the
area actually managed by CBFS, as opposed to ROM_SIZE) that is used to
calculate the CBFS entry start offset. On bottom-aligned boards, many
define a fake (smaller) ROM_SIZE for only the CBFS part, which is not
consistently done and can be an issue because ROM_SIZE is expected to be
a power of two.
This patch changes all non-x86 boards to describe their actual
(physical) ROM size via one of the BOARD_ROMSIZE_KB_xxx options as a
mainboard Kconfig select (which is the correct place to declare
unchangeable physical properties of the board). It also changes the
cbfstool create invocation to use CBFS_SIZE as the -s parameter for
those architectures, which defaults to ROM_SIZE but gets overridden for
special use cases like ChromeOS. This has the advantage that cbfstool
has a consistent idea of where the area it is responsible for ends,
which offers better bounds-checking and is needed for a subsequent fix.
Also change the FMAP offset to default to right behind the (now
consistently known) CBFS region for non-x86 boards, which has emerged as
a de-facto standard on those architectures and allows us to reduce the
amount of custom configuration. In the future, the nightmare that is
ChromeOS's image build system could be redesigned to enforce this
automatically, and also confirm that it doesn't overwrite any space used
by CBFS (which is now consistently defined as the file size of
coreboot.rom on non-x86).

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

This patch adds the macros __ROMSTAGE__ and __RAMSTAGE__ which get
predefined in their respective stages by make, so that we have one
specific macro for every stage. It also renames __BOOT_BLOCK__ and
__VER_STAGE__ to __BOOTBLOCK__ and __VERSTAGE__ for consistency.
This change is intended to provide finer control and clearer
communication of intent after we added a new (optional) stage that falls
under __PRE_RAM__, and will hopefully provide some robustness for the
future (we don't want to end up always checking for romstage with #if
defined(__PRE_RAM__) && !defined(__BOOT_BLOCK__) &&
!defined(__VER_STAGE__) && !defined(__YET_ANOTHER_PRERAM_STAGE__)). The
__PRE_RAM__ macro stays as it is since many features do in fact need to
differentiate on whether RAM is available. (Some also depend on whether
RAM is available at the end of a stage, in which case #if
!defined(__PRE_RAM__) || defined(__ROMSTAGE__) should now be
authoritative.)
It's unfeasable to change all existing occurences of __PRE_RAM__ that
would be better described with __ROMSTAGE__, so this patch only
demonstratively changes a few obvious ones in core code.
BUG=None
TEST=None (tested together with dependent patch).

With CONFIG_RETURN_FROM_VERSTAGE false, the verstage loads the romstage over
the bootblock, then exits to the romstage. this is necessary for some SOC
(e.g. tegra124) which runs the bootblock on a different architecture.
With CONFIG_RETURN_FROM_VERSTAGE true, the verstage returns to the bootblock.
Then, the bootblock loads the romstage over the verstage and exits to the
romstage. this is probably necessary for some SOC (e.g. rockchip) which does not
have SRAM big enough to fit the verstage and the romstage at the same time.

Optimize debugging experience. -Og enables optimizations that do not interfere
with debugging. It should be the optimization level of choice for the standard
edit-compile-debug cycle, offering a reasonable level of optimization while
maintaining fast compilation and a good debugging experience.

Moving the routines that create build.h into a script offers
several advantages. We can create more complex functions to
run and we don't have to deal with both bash and Make at the same
time.
This script combines what is currently in Makefile.inc with a
couple of updates.
- Update how it determines whether to use git for the timestamp
- Move the git revision string generation inside the routine
that checks to see if we have git.
- Add a timeout for the domain name check.

It's a stage in the sense that it has its own set of toolchains,

it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with

When preparing an image for source level debugging, it is convenient

easier to follow the execution flow.
This patch allows to do it by defining GDB_DEBUG=1 in the environment

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.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
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.

00730F01 contains the Avalon southbridge and a Platform Security
Processor (PSP). Supporting the PSP requires specific binaries to
be included in the ROM. The fletcher utility is used to sign PSP
binaries.
The IMC access routines are not accessible for newer AMD parts that
use pre-compiled AGESA. Change the Hudson code such that the IMC
code is not compiled if IMC is not selected in Kconfig.
Disable compilation of resume.c if HAVE_ACPI_RESUME is disabled.
The newer AMD mainboards will initially be released without ACPI
resume support (S3) due to the use of AGESA internals in the
existing Hudson routines. The Makefile change allows newer
mainboards to avoid the API issues.
Change Kconfig such that the FWM flag is always set for PSP-enabled
parts. This has the side effect of forcing the generation of the
FWM directory in the absence of GEC, IMC, and xHCI.

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.

In an abuild run, cbfstool is built in a shared directory
using "make tools". Unfortunately the build system doesn't
actually use that binary directly but creates a per-board
copy (for convenience purposes when editing the image later)
and uses that.
With this change the build system uses the original file but
still creates the copy for the user, avoiding the race while
ensuring convenience.

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.

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.

On newer Intel systems, the flash ROM is shared between the host
processor (BIOS), it's Management Engine (ME) and an integrated ethernet
controller (GbE). The layout of the flash ROM (and other information) is
kept in the so called Intel Firmware Descriptor (IFD). If we only want
to build coreboot to update the BIOS section, all we need is the flash
layout.
This patch adds the option to specify the flash layout in the
mainboard's Kconfig, and thus, to build without the real IFD. However,
with such a build, one has to make sure that the IFD section on the
flash ROM won't be written over (nor any other section that hasn't been
included by coreboot). A patch to write selected sections of a flash ROM
with IFD has been sent to the flashrom mailing list [1].

Add support for SMM modules by leveraging the RMODULE lib. This allows
for easier dynamic SMM handler placement. The SMM module support
consists of a common stub which puts the executing CPU into protected
mode and calls into a pre-defined handler. This stub can then be used
for SMM relocation as well as the real SMM handler. For the relocation
one can call back into coreboot ramstage code to perform relocation in
C code.
The handler is essentially a copy of smihandler.c, but it drops the TSEG
differences. It also doesn't rely on the SMM revision as the cpu code
should know what processor it is supported.
Ideally the CONFIG_SMM_TSEG option could be removed once the existing
users of that option transitioned away from tseg_relocate() and
smi_get_tseg_base().
The generic SMI callbacks are now not marked as weak in the
declaration so that there aren't unlinked references. The handler
has default implementations of the generic SMI callbacks which are
marked as weak. If an external compilation module has a strong symbol
the linker will use that instead of the link one.
Additionally, the parameters to the generic callbacks are dropped as
they don't seem to be used directly. The SMM runtime can provide the
necessary support if needed.

The 'git describe' command is used to obtain the source tree status
information when building coreboot. As used this command expects git
tags to be defined, so it can report the discrepancy between the
current state of the tree and the latest tag.
The problem is that the coreboot source tree does not have any git
tags defined, so when 'git describe' is invoked, it reports "fatal: No
names found, cannot describe anything.". This scary message can be
seen on the console during coreboot builds.
The solution is to add --always to the `git describe' invocation,
which causes it to report the discrepancy with the latest sha1, if
any, which is better than nothing.

For ARM platform, the bootblock may need more C source files to initialize
UART / SPI for loading romstage. To preventing making complex and implicit
dependency by using #include inside bootblock.c, we should add a new build class
"bootblock".
Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.
For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)

In order to provide some insight on what code is executed during
coreboot's run time and how well our test scenarios work, this
adds code coverage support to coreboot's ram stage. This should
be easily adaptable for payloads, and maybe even romstage.
See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for
more information.
To instrument coreboot, select CONFIG_COVERAGE ("Code coverage
support") in Kconfig, and recompile coreboot. coreboot will then
store its code coverage information into CBMEM, if possible.
Then, run "cbmem -CV" as root on the target system running the
instrumented coreboot binary. This will create a whole bunch of
.gcda files that contain coverage information. Tar them up, copy
them to your build system machine, and untar them. Then you can
use your favorite coverage utility (gcov, lcov, ...) to visualize
code coverage.
For a sneak peak of what will expect you, please take a look
at http://www.coreboot.org/~stepan/coreboot-coverage/

- Adding more and more optional and non-optional parameters
bloated cbfstool and made the code hard to read with a lot
of parsing in the actual cbfs handling functions. This change
switches over to use getopt style options for everything but
command and cbfs file name.
- This allows us to simplify the coreboot Makefiles a bit
- Also, add guards to include files
- Fix some 80+ character lines
- Add more detailed error reporting
- Free memory we're allocating

http://netbsd.gw.com/cgi-bin/man-cgi?date++NetBSD-current
The NetBSD manual tells us the date in NetBSD doesn't take any flags
to enable or disable padding in the format.
By default, date pads numeric fields with zeroes. This will convert the
number to octal one. So add "0x" to convert it to BCD directly.

The range of weekday in CMOS is 01-07, while the Sunday is 1, and
Saturday is 7. The comand date in coreutils defines
%u day of week (1..7); 1 is Monday
%w day of week (0..6); 0 is Sunday
There are 1 day offset for each week day. So we use "%w" and plus 1
before we update the weekday in CMOS.

When a power failure happens on the RTC rail, the CMOS memory (including
the RTC registers) is filled with garbage.
So, we erase the full first bank (112 bytes) and we reset the RTC date
to the build date.
To test, disconnect the CMOS battery to produce an RTC power
failure, then boot the machine and observe the RTC date is the build
date using "cat /sys/class/rtc/rtc0/date"
