They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

The devicetree is not made for user-choosable options, thus introduce
Kconfig options for both SGX and the corresponding PRMRR size.
The PRMRR size Kconfig has been implemented as a maximum value. At
runtime the final PRMRR size gets selected by checking the supported
values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest
to the chosen one.
When "Maximum" is chosen, the highest possibly value from the MSR gets
used. When a too strict limit is set, coreboot will die, printing an
error message.

The P2SB PCI device can be "hidden", which causes all sorts of

a good solution to this problem is impossible with FSP into the mix.
Since the values for IBDF and HBDF were already hardcoded as FSP
parameters, define them as macros and use these values directly to
generate the DRHD.

Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.
int sum(size_t n) {
int arr[n];
...
}
This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],
AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
much _slower_ code (and more fragile code), than just using a fixed
key size would have done. [...] Anyway, some of these are definitely
easy to just fix, and using VLA's is actively bad not just for
security worries, but simply because VLA's are a really horribly bad
idea in general in the kernel.
This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

To support generating USB devices in ACPI the platform needs to
know how to determine a device name for each USB port, and for
any root hubs that may be present.
Recent Intel platforms route all ports to an XHCI controller
through a root hub. This is supported by considering the root
hub to be USB port type 0, the USB 2.0 ports to be type 2, and
the USB 3.0 ports to be type 3.
This was tested with a Kaby Lake platform by adding entries to
the devicetree and checking the resulting SSDT.

a Microsoft defined ACPI extension that allows an OS to know what
the debug port is on a system when it is not enabled by the
firmware, so it does not show up in the coreboot tables and
cannot be easily found by a payload.
broadwell: Use byte access device, set up only when enabled since
it relies on the port being put in byte access mode and using
this serial port for debug was not standard in this generation.

There's no reason to mutate the struct device when determining
the ACPI name for a device. Adjust the function pointer
signature and the respective implementations to use const
struct device.

Implement GPIO ACPI AML generating functions that can be called by
coreboot drivers to generate GPIO manipulation code in AML. Following
API functions are implemented:
1. acpigen_soc_read_rx_gpio
2. acpigen_soc_get_tx_gpio
3. acpigen_soc_set_tx_gpio
4. acpigen_soc_clear_tx_gpio
In addition to the API functions above, helper functions are added to
gpio.asl to set/clear/get Tx value of GPIO.

On Apollo Lake it was discovered that our current FADT implementation is
valid for ACPI version 3.0 but misses fields for ACPI version 5.0. We
run into booting issues with Windows 10 using version 5 in the FADT
header. In commit 2b8552f49bc3a7d0290f96a84b573669de396011
(intel/apollolake: Switch FADT to ACPI version 3.0) we go back to
version 3 for Apollo Lake. Skylake is now the last platform that uses
version 5 in FADT header.

Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled
in both DC and AC states. However since using Deep S3 disables some
expected features like wake-on-USB it is not always desired to enable the
same state in both modes.
To address this split the setting and add a separate config for Deep Sx in
AC and DC states.
All motherboards that set this config were updated, but there is no actual
change in behavior in this commit.
BUG=b:36723679
BRANCH=none
TEST=This commit has no runtime visible changes, I verified on Eve that the
Deep SX config registers are unchanged, and it compiles for all affected boards.
