Paul Menzel 526a46ed7e Intel 82801gx: Use 2 << 24 to clarify that I/O APIC ID is 2
Commit »Support for the Intel ICH7 southbridge.« (debb11fc) [1] used
`1 << 25` to set the I/O APIC ID of 2. Instead using `2 << 24`, which
is the same value, makes it clear, that the I/O APIC ID is 2.

Commit »Intel Panther Point PCH: Use 2 << 24 to clarify that APIC ID
is 2« (8c937c7e) [2] is used as a template.

Hung-Te Lin bd7f5f6492 google/snow: Add "wakeup" module for suspend/resume.
The "wakeup" procedure will be shared by bootblock and romstage for different
types of resume processes.

Note, this commit does not include changes in romstage/bootblock to enable
suspend/resume feature. Simply adding functions to handle suspend/resume.

Vladimir Serbinenko 2c88cc0696 Intel microcode: Return when `microcode_updates` is `NULL`
Add a safety check in function `intel_update_microcode` to return when
accidentally `NULL` is passed as `microcode_updates`, which would lead
to a null pointer dereference later on.

    for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {

While at it, use `return NULL` for clarity in function
`intel_microcode_find` and include the header file `stddef.h`. for it.

The review of this patch had some more discussion on adding more
comments and more detailed error messages. But this should be done in
a separate patch.

For clarity here some history, on how this was found and what caused
the discussion and confusion.

Originally when Vladimir made this improvement, selecting
`CPU_MICROCODE_IN_CBFS` in Kconfig but not having the microcode blob
`cpu_microcode_blob.bin` in CBFS resulted in a null pointer dereference
later on causing a crash.

    for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) {

Vladimir fixed this by returning if `microcode_updates` is `NULL`,
that means no file is found and successfully tested this on his
Lenovo X201.

When pushing the patch to Gerrit for review, the code was rewritten
though by Aaron in commit »intel microcode: split up microcode loading
stages« (98ffb426) [1], which also returns when no file is found. So
the other parts of the code were checked and the safety check as
described above is added.

David Hendricks aee444f453 exynos5250: ungate the product ID register
This makes sure that the product ID (PRO_ID) register can be read
when the OS kernel is figuring out what kind of CPU it's running on.

For historical reference, the original U-Boot code seems to have
worked basically by accident here. The hardware has a quirk where by
reading the value before gating the IP block keeps the value
persistent. U-Boot reads the chip ID early on to distinguish between
chip family, but we do not mix code the same way so we do not read
the chip ID. Since the value has been read before the clock gating
happens, the value remains available for the kernel to use during the
decompression stage. We don't want to rely on that behavior when using
coreboot. Instead the kernel should gate unused IPs.

(credit to Gabe for finding symptom in the kernel)

Frank Rysanek c0c620e74a superiotool: add CR dump for W83627UHG = NCT6627UD
This commit adds "register dump capability" to
superiotool for a specific chip by Winbond/Nuvoton:
the W83627UHG   AKA   NCT6627UD  (same chip, different package).
In other words, it fills in the "CR map" definitions in winbond.c,
which so far have been void for this chip.

Paul Menzel 6974396261 AMD SB800 based boards: Use `#include <sb_cimx.h>` instead of `"sb_cimx.h"`
Due to

    $ more src/southbridge/amd/cimx/sb800/Makefile.inc
    […]
    romstage-y += cfg.c
    romstage-y += early.c
    romstage-y += smbus.c

    ramstage-y += cfg.c
    ramstage-y += late.c
    […]

`src/southbridge/amd/cimx/sb800/` is passed with the switch `-I` to
the compiler, where it is also going to find the header file
`sb_cimx.h`. Therefore use `#include <sb_cimx>` everywhere, which is
what some AMD SB800 based boards already do.

The only effect is, that the compiler will not needlessly look into
directories which do not contain the header file [1].

The following command was used for the replacement.

    $ git grep -l sb_cimx.h src/mainboard/ | xargs sed -i 's/#include "sb_cimx.h"/#include <sb_cimx.h>/'

Denis 'GNUtoo' Carikli 4b213a8d1f Intel i945: ACPI: Add _OSC method
Add the ACPI Operating System Capabilities Method and let the
operation system control everything.

Commit »AMD Fam14 DSDT: Add OSC method« (00a0e76b) [1] is used as
a template.

The Lenovo X60 [2] running the Parabola GNU/Linux distribution [3] is
used for testing.

David Hendricks 1fb11d105b armv7/exynos5250: Deprecate sdelay in favor of udelay
This gets rid of the clock-tick based sdelay in favor of udelay().
udelay() is more consistent and easier to work with, and this allows
us to carry one less variation of timers (and headers and sources...).

Every 1 unit in the sdelay() argument was assumed to cause a delay of
2 clock ticks (@1.7GHz). So the conversion factor is roughly:
sdelay(N) = udelay(((N * 2) / 1.7 * 10^9) * 10^6)
          = udelay((N * 2) / (1.7 * 10^3))

The sdelay() periods used were:
sdelay(100) --> udelay(1)
sdelay(0x10000) --> udelay(78) (rounded up to udelay(100))

There was one instance of sdelay(10000), which looked like sort of a
typo since sdelay(0x10000) was used elsewhere. sdelay(10000) should
approximate to about 12us, so we'll stick with that for now and leave
a note.

When looking into possible reasons for a proposed revert [1], I noticed
that the comments use four arguments for `PCIE_DDI_DATA_INITIALIZER`,
but the actual definition only uses three.

    $ git grep -A1 PCIE_DDI_DATA_INITIALIZER # manually squeeze whitespace in output
    […]
    --
    src/vendorcode/amd/agesa/f10/AGESA.h:#define  PCIE_DDI_DATA_INITIALIZER(mConnectorType, mAuxIndex, mHpdIndex ) \
    src/vendorcode/amd/agesa/f10/AGESA.h-{mConnectorType, mAuxIndex, mHpdIndex}
    --
    src/vendorcode/amd/agesa/f10/AGESA.h:   *      PCIE_DDI_DATA_INITIALIZER (ConnectorType
    src/vendorcode/amd/agesa/f10/AGESA.h-   *    },
    --

    src/vendorcode/amd/agesa/f10/AGESA.h-   *    }
    --
    […]

So remove the fourth argument in the comments. Luckily the compiler,
at least gcc, warns about a wrong number of arguments, and therefore
no incorrect code resulted from the wrong documentation.

The fix is simply adding an Else statement to the If which checks
