Starting from here CONFIG_TPM1 and CONFIG_TPM2 are no longer mutually
exclusive.

47e9e8cde1 security/tpm: replace CONFIG(TPMx) checks with runtime check
This prepares the code for enabling both CONFIG_TPM1 and CONFIG_TPM2
during compilation, in which case actual TPM family in use can be
determined at runtime.

In some places both compile-time and runtime checks are necessary.
Yet in places like probe functions runtime state checks don't make sense
as runtime state is defined by results of probing.

bfb11bec3b include/device/device.h: Remove CHIP_NAME() macro
Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:

CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,

This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.

It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

367fff56fa driver/parade to /driver/wwan: Rename Makefiles from .inc to .mk
The .inc suffix is confusing to various tools as it's not specific to
Makefiles. This means that editors don't recognize the files, and don't
open them with highlighting and any other specific editor functionality.

This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.

432e92688e drivers/pc80/rtc/option.c: Reset only CMOS range covered by checksum
Proposed in the comment of commit 29030d0f3d
("drivers/pc80/rtc/option.c: Stop resetting CMOS during s3 resume"),
during sanitize_cmos(), only reset CMOS range covered by checksum and
the checksum itself from the file cmos.default in CBFS, in order to
prevent other runtime data in CMOS (e.g. the DRAM training data on
GM45 platforms for s3 resume) being erased.

Tested: cherry-pick this commit before commit 44a48ce7a4 ("Kconfig:
	Bring HEAP_SIZE to a common, large value"), which is already
	before my commit 29030d0f3d , Thinkpad X200 with
	CONFIG(STATIC_OPTION_TABLE) can resume from s3 again,
	indicating that DRAM training data are no longer erased.

963f7b9e5e security/tpm/: turn tis_{init,open} into tis_probe
init() was always followed by open() and after successful initialization
we only need send-receive function which is now returned by tis_probe()
on success, thus further reducing number of functions to export from
drivers.

This also removes check for opening TIS twice that seems to have no
value.

29030d0f3d drivers/pc80/rtc/option.c: Stop resetting CMOS during s3 resume
After commit e12b313844 ("drivers/pc80/rtc/option.c: Allow CMOS
defaults to extend to bank 1"), Thinkpad X200 with
CONFIG(STATIC_OPTION_TABLE) can no longer resume from s3 (detected via
bisect).

Further inspection shows that DRAM training result of GM45 is stored
in CMOS above 128 bytes in raminit_read_write_training.c, for s3 resume
to restore, but it will be erased by sanitize_cmos(), which now clears
both bank 0 and bank 1, leaving only "untrained" result restored, so s3
resume will fail.

However, resetting CMOS seems unnecessary during s3 resume. Now,
cmos_need_reset will be negated when acpi_is_wakeup_s3() returns true.

Tested: Thinkpad X200 with CONFIG(STATIC_OPTION_TABLE) can resume from
	s3 again with these changes.

8324fe9211 drivers: Add SPDX license headers to Makefiles
To help identify the licenses of the various files contained in the
coreboot source, we've added SPDX headers to the top of all of the
.c and .h files. This extends that practice to Makefiles.

Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.

This patch adds the GPL V2 license identifier to the top of all
makefiles in the drivers directory that don't already have an SPDX
license line at the top.

26a9555073 vga: Change the arguments of vga_write_text to support extended ASCII
VGA defined the extended ASCII set based on CP437, but the function
vga_write_text() accepts a signed char array.

This will cause unnecessary confusion that if we want to print u with
umlaut (code=129 in CP437), we need to explicitly cast it to -127 in
signed char.

Since we still want to leverage the built-in string utilities
which only accepts const char*, we still need to cast it to signed char
while processing, and cast it back to unsigned once we write into the

de74711dc8 vga: Fix the support of extended ASCII
VGA defineds the extended ASCII set based on CP437, but there is a bug
on printing them: in vga_write_at_offset(), we perform a bitwise or
between 'unsigned short' and 'signed char':

```
    p[i] = 0x0F00 | string[i];
```

If we want to show an extended ASCII character, string[i] will be
negative and this bitwise operation will fail due to their implicit
casting rule: convert signed char to unsigned short by adding 65536.

To fix this, we need to cast the string to unsigned char manually
somewhere. Since we still want to leverage the built-in string utilities
which only accepts const char*, we still preserve the original
prototypes before, and cast it until we write into the frame buffer.

3e3b78a391 drivers/pc80/vga: Add API to write multi-line video message
This patch provides an API to allow users to output multi-line
messages using VGA framebuffer.

The current limitation with multiline message is that,
vga_line_write() function is unable to understand newline character
hence, eventually output multiple lines separated with a newline
character with a single line statement.

This patch ensures to parse the entire string and split it into
multiple lines based on the newline character and print each line
separately to the VFG framebuffer.

User can choose to align the output video message as per given choice
between left/center/right of the screen
(i.e. enum VGA_TEXT_ALIGNMENT ).

Additionally, added macros to define the horizontal screen alignment
as well. Ideally if user would like to print the video message at the
middle of the screen then the vertical alignment would be
`VGA_TEXT_CENTER` and horizontal alignment would be
`VGA_TEXT_HORIZONTAL_MIDDLE`.

TEST=Able to build and boot Google/Taeko.

While output a video message such as :

"Your device is finishing an update. This may take 1-2 minutes.\nPlease
do not turn off your device."

Without this patch:

Your device is finishing an update. This may take 1-2 minutes. nPlease
do not turn off your device.

With this patch:

(in Left Alignment):
Your device is finishing an update. This may take 1-2 minutes.
Please do not turn off your device.

(in Right Alignment):
         Your device is finishing an update. This may take 1-2 minutes.
                                    Please do not turn off your device.

(in Center Alignment):
   Your device is finishing an update. This may take 1-2 minutes.
              Please do not turn off your device.

config TPM_GOOGLE_TI50 (new to be used later, implies TPM_GOOGLE)

What protocol the TPM chip supports:
config MAINBOARD_HAS_TPM1

e9665959ed treewide: Remove "ERROR: "/"WARN: " prefixes from log messages
Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.

This patch was created by running

  find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'

and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with

  's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

92ab611c70 drivers/pc80/tpm: Use stopwatch for timeout-loops
There are manual timeout-loops which use a fixed value and udelay().
In all cases there is a debug printk() inside this loop which, when
enabled, takes way longer than the counted microsecond delay. This
leads to the result that e.g. a 1 second delay takes nearly an eternity
if the debug messages are enabled due to the longer function execution
time.

This patch uses the stopwatch scheme for the timeout-loops which still
makes sure that the timeout period is maintained while it takes longer
function calls like printk() into account. In order to keep the minimum
delay between two register accesses on the TPM keep the udelay(1)-call.

TEST=Enable TPM debug messages on a board where the TPM hits a timeout
by failure and make sure that the debug messages occur in the log
just in the timeout period. It still works as expected if the debug
messages are disabled.

power failure while the real date and time registers can contain rubbish
values (can happen when RTC is not buffered). If we do not detect this
invalid date and/or time here and keep it, Linux will use these bad
values for the initial timekeeper init. This in turn can lead to dates
before 1970 in user land which can break a lot assumptions.

reset the values if needed.
