Even though most x86 systems don't run with paging on, it's
helpful to always print it out for the ones that do without
making a more complicated handler. New dump will look like

When employing PAGING_IN_CACHE_AS_RAM more areas need to be
mapped in at runtime. Therefore, paging_identity_map_addr() is
added to support adding identity mappings. Because there are a
fixed amount of pages in cache-as-ram paging only the existing
paging structures can be used. As such that's a limitation on
what regions and length one can map. Using util/x86/x86_page_tables.go
to generate page tables will always populate all the page directory
pages. Therefore, 2MiB mappings are easy to map in.

In some cases it may be useful to be able to bitbang a UART, such as
during early bring-up when a driver for the actual controller isn't
available yet. On some platforms we may even want to use this
permanently, such as on the SDM845 where the hardware UART controller
needs to have firmware loaded and is thus unavailable for most of the
bootblock.
This patch adds some helper code that makes it easy to implement this on
a platform, you just have to pass it a function to control the Tx pin
state and it will do the rest. It relies on the mono_time API and is
thus bound to microsecond timing granularity, but that seems to be
barely good enough for 115200 baud if the bit times are calculated
carefully.

Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.
In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.
The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:
- Remove spi_xfer_two_vectors() which was fusing transactions to
accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
will trigger an error as these controllers can't support the api.

dimm_info.serial had a strange contract. The SPD spec defines a 4 byte
serial number. dimm_info.serial required a 4 character ascii string with
a null terminator.
This change makes the serial field so it matches the SPD spec.
smbios.c will then translate the byte array into hex and set it on the
smbios table.
There were only two callers that set the serial number:
* haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so
it already matches the new contract.
* amd_late_init.c: Previously copied the last 4 characters. Requires
decoding the serial number into a byte array.
google/cyan/spd/spd.c: This could be updated to pass the serial number,
but it uses a hard coded spd.bin.
Testing this on grunt, dmidecode now shows the full serial number:
Serial Number: 00000000

Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.
This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.

AMD's fixed MTRRs have RdDram and WrDram bits that route memory
accesses to DRAM vs. MMIO. These are typically hidden for normal
operation by clearing SYS_CFG[19] (MtrrFixDramModEn). According to
BKDGs and AMD64 Programmer's Manual vol 2, this bit is clear at
reset, should be set for configuration during POST, then cleared for
normal operation.
Attempting to modify the RdDram and WrDram settings without unhiding
them causes a General Protection Fault. Add functions to enable and
disable MtrrFixDramModEn. Unhide/hide as necessary when copying or
writing the fixed MTRRs.
Finally, modify sipi_vector.S to enable the bits prior to writing
the fixed MTRRs and disable when complete.
This functionality is compiled out on non-AMD platforms.

Leverage the stage_cache mechanism to store a non-specific type
of data. This is not interesting when the location for the cache
is in cbmem. However it will be more useful when an external
location is used, e.g. when the cache is in TSEG, locked from user

Write _ROM method and store PCI Option ROM in CBMEM.
Allows an EFI compatible OS to retrieve the Option ROM without the need
to access the PCI BAR. As the Option ROM is no longer present in the
legacy VGA area it's required for mobile platforms. On hybrid devices,
like Lenovo Thinkpads supporting NVIDIA Optimus it's the only way to
retrieve the Option ROM, even with legacy BIOS, as there's no PCI BAR to
map.

* Linux Kernel 4.13.7

If one wants to implement both i2c_bus.h and i2c_simple.h APIs
the compilation unit needs to be guarded or coordinated carefully
with different compilation units. Instead, name the i2c_bus
functions with _dev such that it indicates that they operate on
struct device. One other change to allow i2c_bus.h to be built in
non-ramstage environments is to ensure DEVTREE_CONST is used for
the dev field in struct bus.

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.

This file mostly mimics Porting.h and should be removed.
For now, move it and use it consistently with incorrect form

There have been discussions about removing this since it does not seem
to be used much and only creates troubles for boards without defaults,
not to mention that it was configurable on many boards that do not
even feature uart.
It is still possible to configure the baudrate through the Kconfig
option.

Add a function to retrieve the elapsed time since boot. For that purpose
use the base time in the timestamp table among with the current
timestamp at call time of the function. So more precise the returned
time is the elapsed time since the timestamp was initialized scaled
in microseconds. This was chosen to get a reliable value even on
platforms where the TSC might not be reset on software reset or warm
start.

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.

This patch adds the common acpi code.ACPI code is very similar
accross different intel chipsets.This patch is an effort to
move those code in common place so that it can be shared accross
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.
TEST= Tested the patch as below:
1.Builds and system boots up with the patch.
2.Check all the ACPI tables are present in
/sys/firmware/acpi/tables
3.Check SCI's are properly working as we are
modifying the function to override madt.
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.

Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.
To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.
We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().

Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.
* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

It was added with the words "Update the device header files" and we
maintained it for nearly 13 years :)
These functions are part of the SMBus spec but they are rarely used
and keeping them just in case increases the maintenance burden.

Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.
Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.
The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.
Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.
Patched with Coccinelle using the clumsy spatch below and some manual
changes:
* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.
