This re-factors the Exynos5 I2C code to be simpler and use the
new API, and updates users accordingly.
- i2c_read() and i2c_write() functions updated to take bus number
as an argument.
- Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and
i2c_write(). If a chip needs special handling we should take care
of it elsewhere, not in every low-level i2c driver.
- All the confusing bus config functions eliminated. No more
i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this
is handled automatically when the caller does a transaction and
specifies the desired bus number.
- i2c_probe() eliminated. We're not a command-line utility.
- Let the compiler place static variables automatically. We don't need
any of this fancy manual data placement.
- Remove dead code while we're at it. This stuff was ported early on
and much of it was left commented out in case we needed it. Some
also includes nested macros which caused gcc to complain.
- Clean up #includes (no more common.h, woohoo!), replace debug() with
printk().

The existing header was imported along with the Exynos code and left
mostly unchanged. This is the first patch in a series intended to
replace the imported u-boot I2C API with a much simpler and cleaner
interface:
- We only need to expose i2c_read() and i2c_write() in our public API.
Everything else is board/chip-dependent and should remain hidden
away.
- i2c_read and i2c_write functions will take bus number as an arg
and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to
error and end up cluttering the code since the user needs to save
the old bus number, set the new one, do the read/write, and restore
the old value (3 added steps to do a simple transaction).
- Stop setting default values for board-specific things like SPD
and RTC bus numbers (as if we always have an SPD or RTC on I2C).
- Death to all the trivial inline wrappers. And in case there was any
doubt, we really don't care about the MPC8xx. Though if we did then
we would not pollute the public API with its idiosyncrasies.

Originally developed by LiPPERT and after the acquisition marketed as
'LiPPERT by ADLINK', the plan is now to streamline both boards into the
ADLINK naming scheme. But AFAIK a few have already been sold and as of
this writing the website still advertises the old names. And in any case
the veteran LX products will continue to be sold by ADLINK under their
original names.
So create CONFIG_VENDOR_ADLINK, currently only telling users to look under
LiPPERT (however any future boards will be added here).
Further add an explanation to CONFIG_VENDOR_LIPPERT, and in the Mainboard
model selection show both names.

of the other functions was a bridge, that wouldn't be handled either. The new
version looks at each function that's present no matter what, and if it
discovers that it's a bridge it scans the other side.

Nico Huber commented the following [1].
I don't see those warnings because I build for x86-64. I guess
they could be fixed by casting to `ptrdiff_t` (from stddef.h)
instead of `uint64_t`.
And indeed, using `ptrdiff_t` fixes the warning. But as Stefan
Reinauer commented in [2], `intptr_t` is more appropriate as this
is just a pointer and no pointer difference.
So `intptr_t` is taken, which fixes these issues warned about too.
These warnings were introduced in commit »inteltool: Add support for
dumping AMB registers« (4b7b320f) [3].

The ACPI NVS region was setup in place and there was a CBMEM
table that pointed to it. In order to be able to use NVS
earlier the CBMEM region is allocated for NVS itself during
the LPC device init and the ACPI tables point to it in CBMEM.
The current cbmem region is renamed to ACPI_GNVS_PTR to
indicate that it is really a pointer to the GNVS and does
not actually contain the GNVS.

On certain architectures such as x86 the bootstrap processor
does most of the work. When CACHE_ROM is employed it's appropriate
to ensure that the caching enablement of the ROM is disabled so that
the caching settings are symmetric before booting the payload or OS.
Tested this on an x86 machine that turned on ROM caching. Linux did not
complain about asymmetric MTRR settings nor did the ROM show up as
cached in the MTRR settings.

This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers.
There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.
These devices must be put into "ACPI Mode" in order to take
advantage of S0ix. When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS. When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.
Note that is is not entirely complete yet. We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.
This is hard to test right now because our kernel does not support
any of these devices in ACPI mode. I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree. With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.
I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.

The TPM code wasn't previously honoring MOCK_TPM=1. Because of this,
boards with TPMs that didn't handle S3 resume properly would cause a
hard reset. Allow one to build with MOCK_TPM=1 on the command line so
that S3 can still work.

The new enable_pm1() function was doing 2 things wrong:
1. It was doing a RMW of the pm1 register. This means we were
keeping around the enables from the OS during S3 resume. This
is bad in the face of the RTC alarm waking us up because it would
cause an infinite stream of SMIs.
2. The register size of PM1_EN is 16-bits. However, the previous
implementation was accessing it as a 32-bit register.
The PM1 enables should only be set to what we expect to handle in the
firmware before the OS changes to ACPI mode.

The GCC documentation states [1]
In some contexts this shortcut is undesirable. The -Wundef option
causes GCC to warn whenever it encounters an identifier which is
not a macro in an ‘#if’.
and therefore use `#ifdef` [2] to silence this warning. No functional
change is done, as `CONFIG_SPEAKER` is assigned the value `Y` when
defined.
There was some discussion going on the list [3], but my points in there
turned out to be incorrect.

Previously southbridge_smm_init() was provided that did both
the clearing of the SMM state and enabling SMIs. This is
troublesome in how haswell machines bring up the APs. The BSP
enters SMM once to determine if parallel SMM relocation is possible.
If it is possible the BSP releases the APs to do SMM relocation.
Normally, after the APs complete the SMM relocation, the BSP would then
re-enter the relocation handler to relocate its own SMM space.
However, because SMIs were previously enabled it is possible for an SMI
event to occur before the APs are complete or have entered the
relocation handler. This is bad because the BSP will turn off parallel
SMM save state. Additionally, this is a problem because the relocation
handler is not written to handle regular SMIs which can cause an
SMI storm which effectively looks like a hung machine. Correct these
issues by turning on SMIs after all the SMM relocation has occurred.
