32bba1877b acpi/acpigen: introduce acpigen_write_processor_device
The ACPI PROCESSOR_OP has been deprecated in ACPI 6.0 and dropped in
ACPI 6.4 and is now permanently reserved. As a replacement, DEVICE_OP
with the special HID ACPI0007 should be used instead. This special HID
was introduced in version 3 of the ACPI spec. To have a function to
generate this, acpigen_write_processor_device is introduced. The CPU
index is used as UID which can be assumed to be unique.

b57b12f729 acpi/acpigen: factor out acpigen_write_processor_namestring
This functionality is used in multiple places, so factor it out into a
function. Compared to acpigen_write_processor_cnot, the buffer size is
decreased from 40 to 16 bytes, but the format string specified by
CONFIG_ACPI_CPU_STRING results in 9 chars and a NULL byte which will fit
into the buffer without any issue. I've seen the CPU devices being put
into another scope within \_SB, but even in that case that would be 14
chars and a NULL byte whist still fits into the 16 byte buffer. For
acpigen_write_processor and acpigen_write_processor_package this doesn't
change any edge case behavior. In the unrealistic case of the format
string resulting in a longer CPU device string, this would have been a
problem before this patch too.

Also drop the curly braces of the for loop in
acpigen_write_processor_package. This makes the code a bit harder to
read and isn't a very good idea, but with the curly braces in place, the
linter breaks the build :(

2fc2758e51 acpi/Kconfig: improve description of ACPI_CPU_STRING config option
ACPI_CPU_STRING specifies the format string for the scope of the
processor devices in the generated ACPI code. Also point out that the
resulting string will be truncated to at most 15 chars to fit into the
16 byte buffer used in two functions in acpigen.c.

e608308ade src/acpi: add debug message with concatenated string
add functions for concatenate OP
add debug message containing concatenated string with string, value, or
OPs

Ex1: to print string with another string provided from C side:
acpigen_write_debug_concatenate_string_string("Wait loop Timeout! var=",
            name, LOCAL6_OP);
will generate:
    Concatenate ("Wait loop Timeout! var=", "L23E", Local6)
    Debug = Local6

Ex2: to print string with a value:
acpigen_write_debug_concatenate_string_int("ModPHY enabling for RP:",
    pcie_rp, LOCAL0_OP);

will generate:
    Concatenate ("ModPHY enabling for RP:", 0x05, Local0)
    Debug = Local0

Ex3: to print string with an ACPI OP:
acpigen_write_debug_concatenate_string_op("while Loop count: ",
    LOCAL7_OP, LOCAL6_OP)

will generate:
    Concatenate ("while Loop count: ", Local7, Local6)
    Debug = Local6

TEST=Add above functions in the acpigen code and check the generated
SSDT table after OS boot

d5d9b280de acpi/acpi.c: Fix einj generation pointer arithmetics
Without a cast the aritmetics of

tat = einj + sizeof(acpi_einj_smi_t)

is the same as

tat = (uintptr_t)einj + size(acpi_einj_smi_t) * size(acpi_einj_smi_t)

So it overshoots the intended offset by a lot.

This issue only came apparent because now einj is in the small IMD
region which is close to TSEG. With the wrong aritmetics the tat
pointer ended up inside TSEG which is not accessible from the OS
causing exceptions.

TEST: observe that tat pointer is inside the small IMD below
TSEG (0x78000000 on our setup).
"acpi_create_einj trigger_action_table = 0x77ffe89c"

Reason for revert: Gmeet resolution dropped. When system starts
Gmeet video call, it uses the hardware accelerated encoder as per

Due to this, Gmeet resolution dropped from 720p to 180p.

platforms. This issue is not seen on fan based systems.

5cf02a4ecd lib/hardwaremain.c: Move creating ACPI structs to bootstate hooks
hardwaremain.c is the common ramstage entry to all platforms so move
out ACPI code generation (x86 specific) to boot state hooks.

Another reason to do this is the following:
On some platforms that start in dram it makes little sense to have
separate stages. To reduce the complexity we want to call the ramstage
main function instead of loading a full stage. To make this scheme
more maintainable it makes sense to move out as much functionality
from the 'main' function as possible.

2e7e2d978b coreboot_tables.c: Expose the ACPI RSDP
The ACPI RSDP can only be found in:
- legacy BIOS region
- via UEFI service

On some systems like ARM that legacy BIOS region is not an option, so
to avoid needing UEFI it makes sense to expose the RSDP via a coreboot
table entry.

This also adds the respective unit test.

972d9f2cce arch/x86: consolidate HPET base address definitions
Both the HPET_BASE_ADDRESS define from arch/x86/include/arch/hpet.h and
the HPET_ADDRESS Kconfig option define the base address of the HPET MMIO
region which is 0xfed00000 on all chipsets and SoCs in the coreboot
tree. Since these two different constants are used in different places
that however might end up used in the same coreboot build, drop the
Kconfig option and use the definition from arch/x86 instead. Since it's
no longer needed to check for a mismatch of those two constants, the
corresponding checks are dropped too.

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'
