Changes:
- Get rid of the h8scm mainboard specific code and use the
platform generic function wrapper that was added in change
http://review.coreboot.org/#/c/2777/
AMD Fam15: Add SPD read functions to wrapper code
- Move DIMM addresses into devicetree.cb
Notes:
- The DIMM reads only happen in romstage, so the function is not
available in ramstage. Point the read-SPD callback to a generic
function in ramstage.

is specific to the dinar mainboard configuration and was therefore

This code is taken from an EDID reader written at Red Hat.
The key function is
int decode_edid(unsigned char *edid, int size, struct edid *out)
Which takes a pointer to an EDID blob, and a size, and decodes it into
a machine-independent format in out, which may be used for driving
chipsets. The EDID blob might come for IO, or a compiled-in EDID
BLOB, or CBFS.
Also included are the changes needed to use the EDID code on Link.

This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

For full integration of FUI into coreboot, we need aux channel
communcations. The intel_dp.c is a file taken from Linux and is
used for aux channel comms. This file has been cut down to work
with coreboot. For now it is associated with the link mainboard
until we get a better handle on how this all fits together. This
code is almost certainly usable on other platforms in the long term.
But one step at a time.

This adds a new API for cache maintenance operations. The idea is
to be more explicit about operations that are going on so it's easier
to manage branch predictor, cache, and TLB cleans and invalidations.
Also, this adds some operations that were missing but required early
on, such as branch predictor invalidation. Instruction and sync
barriers were wrong earlier as well since the imported API assumed
we compield with -march=armv5 (which we don't) and was missing
wrappers for the native ARMv7 ISB/DSB/DMB instructions.
For now, this is a start and it gives us something we can easily use
in libpayload for doing things like cleaning and invalidating dcache
when doing DMA transfers.
TODO:
- Set cache policy explicitly before re-enabling. Right now it's left
at default.
- Finish deprecating old cache maintenance API.
- We do an extra icache/dcache flush when going from bootblock to
romstage.

Having this header file in the mainboard directory breaks
the dinar build on cygwin because the header file in the
dinar mainboard is used instead of the correct header file
src/vendorcode/amd/cimx/sb700/OEM.h. The build probably works
fine on Linux systems because, due to case-sensitivity, Oem.h
will not match the #include "OEM.h" statement in
src/southbridge/amd/cimx/sb700/Platform.h.
The Oem.h file in the dinar mainboard is not used by any other
source files, and the defines in the dinar mainboard are duplicated
by defines in the correct OEM.h file. Therefore, the file can be
safely removed.

This commit pulls in all the common logic for romstage into
the Haswell cpu directory. The bits specific to the mainboard
still reside under their respective directories. The calling
sequence bounces from the cpu directory to mainboard then back
to the cpu directory. The reasoning is that Haswell systems use
cache-as-ram for backing memory in romstage. The stack is used to
allocate structures. However, now changes can be made to the
romstage for Haswell and apply to all boards.

It was found that the Haswell reference code was smashing through the
stack into the reference code's heap implementation. The reason for this
is because our current CAR allocation is too small. Moreover there are
quite a few things to coordinate between 2 code bases to get correct.
This commit separates the CAR into 2 parts:
1. MRC CAR usage.
2. Coreboot CAR usage.
Pointers from one region can be passed between the 2 modules, but one
should not be able to affect the others as checking has been put into
place in both modules.
The CAR size has effectively been doubled from 0x20000 (128 KiB) to
0x40000 (256KiB). Not all of that increase was needed, but enforcing
a power of 2 size only utilizes 1 MTRR.
Old CAR layout with a single contiguous stack with the region starting
at CONFIG_DCACHE_RAM_BASE:
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
| MRC global variables |
| CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+
| ROM stage stack |
| |
| |
+---------------------------------------+
| MRC Heap 30000 bytes |
+---------------------------------------+
| ROM stage console |
| CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
| ROM stage CAR_GLOBAL variables |
+---------------------------------------+ Offset 0
There was some hard coded offsets in the reference code wrapper to start
the heap past the console buffer. Even with this commit the console
can smash into the following region depending on what size
CONFIG_CONSOLE_CAR_BUFFER_SIZE is.
As noted above This change splits the CAR region into 2 parts starting
at CONFIG_DCACHE_RAM_BASE:
+---------------------------------------+
| MRC Region |
| CONFIG_DCACHE_RAM_MRC_VAR_SIZE bytes |
+---------------------------------------+ Offset CONFIG_DCACHE_RAM_SIZE
| ROM stage stack |
| |
| |
+---------------------------------------+
| ROM stage console |
| CONFIG_CONSOLE_CAR_BUFFER_SIZE bytes |
+---------------------------------------+
| ROM stage CAR_GLOBAL variables |
+---------------------------------------+ Offset 0
Another variable was add, CONFIG_DCACHE_RAM_ROMSTAGE_STACK_SIZE,
which represents the expected stack usage for the romstage. A marker
is checked at the base of the stack to determine if either the stack
was smashed or the console encroached on the stack.

Rather than have to repeat this bit in every mainboard.
Also, remove the reset of the RTC power status from here.
We had done this in TOT for current platforms but did not
carry it back to emeraldlake2 where this branched from.
If we clear the status here then we don't get an event
logged later which can be important for the devices that
do not have a CMOS battery.

There was a mix of setup code sprinkled across the various components:
southbridge code in the northbridge, etc. This commit reorganizes the
code so that northbridge code doesn't initialize southbridge components.
Additionally, the calling dram initialization no longer calls out to ME
code. The main() function in the mainboard calls the necessary ME
functions before and after dram initialization.
The biggest change is the addition of an early_pch_init() function
which initializes the BARs, GPIOs, and RCBA configuration. It is also
responsible for reporting back to the caller if the board is being
woken up from S3. The one sequence difference is that the RCBA config
is performed before claling the reference code.
Lastly the rcba configuration was changed to be table driven so that
different board/configurations can use the same code. It should be
possible to have board/configuration specific gpio and rcba
configuration while reusing the romstage code.

Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'
By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`. PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge. However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

The _OSC method is used to tell the OS what capabilities

is described in chapter 6.2.9 of the ACPI spec v3.0.
The method takes 4 inputs (UUID, Rev ID, Input Count,

is generally 3 Dwords long consisting of an Errors
Dword, a Supported Capabilities Dword, and a Control

capabilities and the firmware must grant or deny control
of those features. We do not want to have control over
anything so let the OS control as much as it can.

Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'
By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`. PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge. However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

I am removing the _INI method from the AZHD device because
it does not seem to do anything and causes errors in the
FWTS[1] (Firmware Test Suite) test 'method'. The INI
method performs device specific initialization and is
run when OSPM loads a description table. It must only
access OperationRegions that have been indicated as
available by the _REG (Region) method. We do not have a
_REG method and during my testing, I added a REG method
but it did not seem to make a difference in the PCI
register space. The bit fields defined as NSDI (Disable
No Snoop), NSDO (Disable No Snoop Override), and NSEN
(Enable No Snoop Request) do not ever get written from
their default values. And writing to these bit fields
does not seem to be necessary because I did not notice
any change in audio functionality.
In an effort to clean up as many FWTS errors as possible,
I propose removing this method altogether. I have seen no
change in operation (audio works with and without this
method) and there does not seem to be any change in lspci
or dmesg.
FWTS information can be found here:

The CS5536 companion device has three different power domains.
* working domain
* standby domain
* RTC domain
When the system is "off" only the standby domain is powered.
MFGPT[7:6] are member of the standby power domain.
MFGPT7 is used to control the backlight of the device and so the
timer gets used and configured during system boot. If the system
does a reboot the timer stays configured and the Linux driver
can not use it:
"ot200-backlight: ot200-backlight.0: MFGPT 7 not availale"
The cs5535-mfgpt has a function to hard-reset all MFGPTs but the
system hangs after the first access to a MFGPT register - cause
unknown.
/*
* This is a sledgehammer that resets all MFGPT timers. This is required by
* some broken BIOSes which leave the system in an unstable state
* (TinyBIOS 0.98, for example; fixed in 0.99). It's uncertain as to
* whether or not this secret MSR can be used to release individual timers.
* Jordan tells me that he and Mitch once played w/ it, but it's unclear
* what the results of that were (and they experienced some instability).
*/
static void reset_all_timers(void)
{
uint32_t val, dummy;
/* The following undocumented bit resets the MFGPT timers */
val = 0xFF; dummy = 0;
wrmsr(MSR_MFGPT_SETUP, val, dummy);
}
After playing around with this undocumented MSR it looks like I only
need to set bit 7 to free the MFGPT7.
BTW, all MFGPT[0:5] will be reset during pll_reset().

Change the OSC method to actually grant control of
PCIe capabilities to the OS instead of granting no
control. I believe the logic was backwards in the
original commit. Bits should be set when granting
control and cleared when not granting control. By
setting the return value to 0x00, we effectively
tell the OS that it cannot control any PCIe
capability. See section 6.2.9 of the ACPI spec
version 3.0 for more information.
This edit is a duplication of the OSC method that
is in the src/southbridge/intel/bd82x6x/pch.asl
file.

This sets up the bus number for the PCI0 device
