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.

The IMC access routines are not accessible for newer AMD parts that

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

Change Kconfig such that the FWM flag is always set for PSP-enabled

Provide functionality to create dynamic classes based on program name and

takes program_name and arch as its arguments and adds the program_name to

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

One such example of dynamic class is rmodules. Multiple rmodules can be used

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.

On newer Intel systems, the flash ROM is shared between the host

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

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/

After collecting dependencies for ramstage, add an intermediate step
in which object files are linked per directory. The results are then
linked into the final binary.
This reduces the maximum command line length and might also help with
future use of LTO linking.
Also adapt the lint test for build dir handling, since printall
doesn't provide individual object files for ramstage anymore.

The use of ramstage.a required the build system to handle some
object files in a special way, which were put in the drivers
class.
These object files didn't provide any symbols that were used
directly (but only via linker magic), and so the linker never
considered them for inclusion.
With ramstage.a gone, we can drop this special class, too.

Right now coreboot's build process produces images that are
not booting on actual hardware because they are smaller than
the actual flash device and also don't have an IFD nor an ME
firmware in them. In order to produce bootable images, you
needed a wrapper script / extra step until now. With this
change, the resulting coreboot.rom is actually bootable.

- 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

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"
