Arthur Heymans b29078e401 mb/*/*: Remove rtc nvram configurable baud rate
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.

Werner Zeh 35cceb861c timestamp: Add function to get time since boot
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.

Kyösti Mälkki d07f377872 usbdebug: Fix init and add support for postcar
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.

Aaron Durbin 5a1f9a87cb cpu/x86/mp_init: remove adjust_cpu_apic_entry()
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.

Shaunak Saha bd427803ab soc/intel/common/block: Common ACPI
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.

Edward O'Callaghan 1104c278e3 cpu/x86/smm: Fix explicit 'addr32' usage in clang builds
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.

Nico Huber 581738642f Reinvent I2C ops
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().

Nico Huber 029dfff30c i2c: Move to Linux like `struct i2c_msg`
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`.

Call weak method die_notify.

The method should be overwritten in mainboard directory to signal that
a fatal error had occurred. On boards that do share the same EC and where
the EC is capable of controlling LEDs or a buzzer the method can be
overwritten in EC directory instead.

Tested on Lenovo T500.

This patch uses struct device explicitly for the ramstage functions
as that's the actual type it's working on. Additionally, the
declarations for types and functions are fully exposed so that
compliation units don't have to guard certain functions from use
because it's being compiled for multiple stages.

This patch replaces all these similar and mostly identical

This also makes i2c block read available to all those southbridges.
If the northbridge has to read a lot of SPD bytes sequentially, using
this function can reduce the time being spent to read SPD five-fold.

now also remove the coreboot infrastructure that supported it. It

Julius Werner b8534f767c assert: Add new dead_code() macro to assert dead code paths
This patch adds a new kind of compile-time assertion based on Linux'
compiletime_assert(). The difference to the existing use of
_Static_assert() in coreboot (which should continue to be used where
appropriate) is that this new assertion only hits if the call to it is
not optimized out at compile time. It is therefore ideal to assert that
certain code paths are not included in the image if a certain Kconfig
option is (not) set. For example,

 assert(!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE));

can be rewritten as

 if (!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE))
   dead_code("This code shouldn't be built for config X");

to turn it into a compile-time check.
