There is common HDA code in soc/intel/common that provides generic
HDA support functions, but it does not provide a driver.
This change adds a common block driver for HDA that provides a
ramstage driver for SOCs that need to initialize an HDA codec.
This was tested on a board with an HDA codec to ensure that it
properly detected it and ran the codec init steps.

It's logic manages saving non-volatile areas into the boot media.
Therefore, expose it to the rest of the system for any and all to

As noted on linux-pci, we have a weird way to handling "value" and
"scale" fields that are supposed to contain numerical values: we encode
them as a bitfield.
Instead define the two fields (offset and mask) and use numbers.
Another issue, not fixed in this CL, is that we write hard-coded values
while these fields really need to contain the max() of acceptable delays
of the downstream devices. That way the controller can decide whether or
not to enter a deeper power management state. It's noted as a TODO.

On many recent Chrome OS boards, the desire to unite more configurations
under the same image has led to the need of a "SKU ID" that identifies
different configurations of the same board (e.g. with certain optional
components stuffed or not stuffed, or replaced with a comparable
component). This is markedly different from the existing "board ID",
because that is reserved to count "revisions" -- changes made to the
same configuration over time during the development process. This patch
adds support to have a mainboard define this SKU ID and pass it through
the coreboot table like we already have for board IDs.

Merge the different coreboot table strapping ID structures into one
because they're really just all the same, and I want to add more. Make
the signature of the board_id() function return a uint32_t because
that's also what goes in the coreboot table. Add a printk to the generic
code handling strapping IDs in ramstage so that not every individual
mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)

The BOARD_ID_MANUAL and BOARD_ID_STRING options were introduced for the
Urara board which is now long dead, and have never been used anywhere
else. They were trying to do something that we usually handle with a
separate SKU ID these days, whereas BOARD_ID is supposed to be reserved
for different revisions of the same board/SKU. Get rid of it to make
further refactoring of other options easier.
Also shove some stuff back into the Urara mainboard that should've never
crept into generic headers.

This further allows compilation units to be re-used without
having to add macro guards because of declarations not being
around in the __SIMPLE_DEVICE__ case. These declarations are for
functions that operate on struct device. struct device is a known
type so just expose the functions using the correct type. Also,
DEVTREE_CONST is empty while in ramstage so there's no reason
to separate the declarations. Lastly, fix up device_util.c to
use the proper types. It's only compiled in ramstage and it only
operates on struct device.

use the base time in the timestamp table among with the current

platforms where the TSC might not be reset on software reset or warm

It was originally designed such that if usbdebug_init() was called
before cbmem_initialize(), it would fetch the already-initialized
state from CBMEM. This changed when cbmem_find() behaviour changed
to require cbmem_initialize() to be called first. As a result,
ramstage had to reinitialize all of the EHCI controller and USB
endpoints on entry. This was slow, specially with AMD hardware
where one can scan USB ports to probe for the debug dongle.
For postcar and ramstage, move usbdebug entry such that it is
triggered from CBMEM_INIT_HOOK instead of console_init().
Side-effect of this is usbdebug console shows 'coreboot-xxx ...
starting...' line only for romstage.
Initialisation for usbdebug is never done in postcar. If you have
USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on
usb either.
While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE
and alike.

The original purpose of adjust_cpu_apic_entry() was to set
up an APIC map. That map was effectively only used for mapping
*default* APIC id to CPU number in the SMM handler. The normal
AP startup path didn't need this mapping because it was whoever
won the race got the next cpu number. Instead of statically
calculating (and wrong) just initialize the default APIC id
map when the APs come online. Once the APs are online the SMM
handler is loaded and the mapping is utilized.

different intel platforms instead of duplicating for each platform.
We are removing the common acpi files in src/soc/intel/common.
This removes the acpi.c file which was previously in
src/soc/common/acpi. The config for common acpi is
SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's
Kconfig file in order to use the common ACPI code. This patch also
includes the changes in APL platform to use the common ACPI block.

3.Check SCI's are properly working as we are

4.Extract acpi tables like DSDT,APIC, FACP, FACS
and decompile the by iasl and compare with good
known tables.
5.Execute the extracted tables in aciexec to check
acpi methods are working properly.

The addr32 prefix is required by binutils, because even when
given an explicit address which is greater than 64KiB, it will
throw a warning about truncation, and stupidly emit the opcode
with a 16-bit addressing mode and the wrong address.
However, in the case of LLVM, this doesn't happen, and is happy
to just use 32-bit addressing whenever it may require it. This
means that LLVM never really needs an explicit addr32 prefix to
use 32-bit addressing in 16-bit mode.
