Patrick Georgi 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.

about the implementations behind the regions. Additionally, this

CONSOLE     7. 023d8000 00020000

After with tiered imd:

IMD SMALL   1. 023fe000 00001000
aaaacccc    2. 023fc000 00001060
aaaacccd    3. 023fb000 000007cf
CONSOLE     4. 023db000 00020000
COREBOOT    5. 023d9000 00002000
IMD small region:
  IMD ROOT    0. 023fec00 00000400
  aaaabbbb    1. 023febe0 00000020

  aaaabbbe    3. 023feb20 00000080
  ROMSTAGE    4. 023feb00 00000004

Side note: this CL provides a basis for what hoops one needs to
jump through when there are not writeable global variables on
a particular platform in the early stages.

Aaron Durbin 20686d851c coreboot: add imd library
The imd (internal memory database) library provides a way to
track memory regions by assigning ids to each region. The implementation
is a direct descendant of dynamic cbmem. The intent is to replace
the existing mechanisms which do similar things: dynamic cbmem, stage
cache, etc.

Differences between dynamic cbmem and imd:
- All structures/objects are relative to one another. There
  are no absolute pointers serialized to memory.
- Allow limiting the size of the idm. i.e. provide a maximum
  memory usage.
- Allow setting the size of the root structure which allows
  control of the number of allocations to track.

Adding a new field to a CBMEM structure does not work if there are
systems with older RO that do not have this new field as it means
romstage did not prepare the field and ramstage is using it

To deal with this instead of adding a new field split the existing
s3_resume variable into bytes, using the first byte for the existing
s3_resume variable (which is always just 0 or 1) and the second byte
for the new varible, which will always be 0 for the old RO and can
be set by new RO.

Julius Werner d82e0cf331 Fix non-x86 __PRE_RAM__ assertions and add FATAL_ASSERTS Kconfig option
This patch fixes a bug that caused non-x86 boards to use the poor man's
assert() version with a lot more instructions per invocation and
hexadecimal line numbers in __PRE_RAM__ environments. This was really
just an oversight in the ARM port... even x86 uses a proper printk() in
most cases (those with CAR) and there's no reason not to do so on the
generally even more flexible SRAM-based architectures.

Additionally, it adds a new Kconfig option to make failed assertions and
BUG() calls halt again. This seems to have been the original intention,
but was commented out once out of fear that this might prevent
production systems from booting. It is still a useful debugging feature
though (since otherwise assertions can easily just scroll past and get
overlooked), so the user should be able to decide the this based on his
needs.

(Also changed error messages for both to include the word "ERROR", since
grepping for that is the most sophisticated way we currently have to
detect firmware problems. Some automated Chromium OS suspend tests check
for that.)

This patch introduces a new option (CONFIG_MULTIPLE_CBFS_INSTANCES) to
allow multiple CBFS instances in the bootrom.

When the new option is enabled, the code running on the target
controls which CBFS instance is used. Since all other then header CBFS
structures use relative addressing, the only value which needs
explicit setting is the offset of the CBFS header in the bootrom.

This patch adds a facility to set the CBFS header offset. The offset
value of zero means default. i.e. the CBFS initialization code still
discovers the offset through the value saved at the top of the ROM.

Julius Werner 249f9ccacb rk3288: Handle framebuffer through memlayout, not the resource system
We've traditionally tucked the framebuffer at the end of memory (above
CBMEM) on ARM and declared it reserved through coreboot's resource
allocator. This causes depthcharge to mark this area as reserved in the
kernel's device tree, which may be necessary to avoid display corruption
on handoff but also wastes space that the OS could use instead.

Since rk3288 boards now have proper display shutdown code in
depthcharge, keeping the framebuffer memory reserved across the handoff
(and thus throughout the lifetime of the system) should no longer be
necessary. For now let's just switch the rk3288 implementation to define
it through memlayout instead, which is not communicated through the
coreboot tables and will get treated as normal memory by depthcharge.
Note that this causes it to get wiped in developer/recovery mode, which
should not be a problem because that is done in response to VbInit()
(long before any images are drawn) and 0 is the default value for a
corebootfb anyway (a black pixel).

Eventually, we might want to think about adding more memory types to
coreboot's resource system (e.g. "reserved until kernel handoff", or
something specifically for the frame buffer) to model this situation
better, and maybe merge it with memlayout somehow.

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.

TEST=Observed parameters to be passed up to depthcharge through

Vadim Bendebury 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.

Julius Werner a7d924412a timestamps: You can never have enough of them!
Now that we have timestamps in pre-RAM stages, let's actually make use
of them. This patch adds several timestamps to both the bootblock and
especially the verstage to allow more fine-grained boot time tracking.

Some of the introduced timestamps can appear more than once per boot.
This doesn't seem to be a problem for both coreboot and the cbmem
utility, and the context makes it clear which operation was timestamped
at what point.

Also simplifies cbmem's timestamp printing routine a bit, fixing a
display bug when a timestamp had a section of exactly ",000," in it

Julius Werner 44cf870cb0 timer: Reestablish init_timer(), consolidate timer initialization calls
We have known for a while that the old x86 model of calling init_timer()
in ramstage doesn't make sense on other archs (and is questionable in
general), and finally removed it with CL:219719. However, now timer
initialization is completely buried in the platform code, and it's hard
to ensure it is done in time to set up timestamps. For three out of four
non-x86 SoC vendors we have brought up for now, the timers need some
kind of SoC-specific initialization.

This patch reintroduces init_timer() as a weak function that can be
overridden by platform code. The call in ramstage is restricted to x86
(and should probably eventually be removed from there as well), and
other archs should call them at the earliest reasonable point in their
bootblock. (Only changing arm for now since arm64 and mips bootblocks
are still in very early state and should sync up to features in arm once
their requirements are better understood.) This allows us to move
timestamp_init() into arch code, so that we can rely on timestamps
being available at a well-defined point and initialize our base value as
early as possible. (Platforms who know that their timers start at zero
can still safely call timestamp_init(0) again from platform code.)

Julius Werner efcee767de CBFS: Automate ROM image layout and remove hardcoded offsets
Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.

Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).

Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

Vadim Bendebury f9ff353430 spi: support controllers with limited transfer size capabilities
Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI
read and write transactions. Limiting transfer size in the wrapper
allows to provide the API user with unlimited transfer size
transactions.

The tranfer size limitation is added to the spi_slave structure, which
is set up by the controller driver. The value of zero in this field
means 'unlimited transfer size'. It will work with existion drivers,
as they all either keep structures in the bss segment, or initialize
them to all zeros.

This patch addresses the problem for reads only, as coreboot is not
expected to require to write long chunks into SPI devices.

Marc Jones 9afc5c05f0 baytrail: Switch from ACPI mode to PCI mode for legacy support
Most Baytrail based devices MMIO registers are reported in ACPI
space and the device's PCI config space is disabled. The PCI config
space is required for many "legacy" OSs that don't have the ACPI
driver loading mechanism. Depthcharge signals the legacy boot
path via the SMI 0xCC and the coreboot SMI handler can switch the
device specific registers to re-enable PCI config space.
