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.

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
it can take control over from the firmware. This method
is described in chapter 6.2.9 of the ACPI spec v3.0.
The method takes 4 inputs (UUID, Rev ID, Input Count,
and Capabilities Buffer) and returns a Capabilites
Buffer the same size as the input Buffer. This Buffer
is generally 3 Dwords long consisting of an Errors
Dword, a Supported Capabilities Dword, and a Control
Dword. The OS will request control of certain
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.
The _OSC method is required for PCIe devices and dmesg
checks for its existence and issues an error if it is
not found.

The Link native graphics commit 49428d84 [1]
Add support for Google's Chromebook Pixel
was missing some of the higher level bits, and hence could not be
used. This is not new code -- it has been working since last
August -- so the effort now is to get it into the tree and structure
it in a way compatible with upstream coreboot.
1. Add options to src/device/Kconfig to enable native graphics.
2. Export the MTRR function for setting variable MTRRs.
3. Clean up some of the comments and white space.
While I realize that the product name is Pixel, the mainboard in the
coreboot tree is called Link, and that name is what we will use
in our commits.

Currently the OS is free to use the memory located at the default
SMRAM space because it is not marked reserved in the e820. This can
lead to memory corruption on S3 resume because SMM setup doesn't save
this range before using it to relocate SMRAM.

The previous code w.r.t. resource allocation was getting lucky
based on the way fixed mmio resources on the system were being
chosen. Namely, PCIEXBAR was the lowest mmio space and the other
fixed non-standar BARs were above it. The resource allocator would
then start allocating standard BARs below that.
On top of that other resources were being added when
dev_ops->set_resources() was being called on the PCI domain. At that
point the PCI range limit were already picked for where to start
allocating from.
To ensure we no longer get lucky during resource allocation add the
fixed resources in the host bridge and add the memory controller
cacheable memory areas. With those resources added the range limit
for standard PCI BARs is chosen properly.
Depending on haswell board configurations we may need to adjust and
pass in the size of physical address space needed for PCI resources
to the reference code. For the time being the CRBs appear to be OK.
Lastly, remove the SNB workaround for reserving 2MiB at 1GiB and 512MiB.

This commit updates the Lynx Point resource reservations before
the coreboot allocator assigns resources. There is no need to mark
anything as subtractive decode because there are no devices/buses
linked to the LPC device.
The I/O range reservations consists of claiming the first 4KiB
of I/O space. The PMBASE, GPIOBASE, and LPC generic I/O decode
ranges are checked against the default claimed range. If those
ranges overlap or fall outside of the default range then those
resources are added.
The MMIO range reservations consist of claiming everything from
the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range
register are then conditionally added if they fall outside of
the default MMIO range.

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().

Add support for SMM modules by leveraging the RMODULE lib. This allows
for easier dynamic SMM handler placement. The SMM module support
consists of a common stub which puts the executing CPU into protected
mode and calls into a pre-defined handler. This stub can then be used
for SMM relocation as well as the real SMM handler. For the relocation
one can call back into coreboot ramstage code to perform relocation in
C code.
The handler is essentially a copy of smihandler.c, but it drops the TSEG
differences. It also doesn't rely on the SMM revision as the cpu code
should know what processor it is supported.
Ideally the CONFIG_SMM_TSEG option could be removed once the existing
users of that option transitioned away from tseg_relocate() and
smi_get_tseg_base().
The generic SMI callbacks are now not marked as weak in the
declaration so that there aren't unlinked references. The handler
has default implementations of the generic SMI callbacks which are
marked as weak. If an external compilation module has a strong symbol
the linker will use that instead of the link one.
Additionally, the parameters to the generic callbacks are dropped as
they don't seem to be used directly. The SMM runtime can provide the
necessary support if needed.

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

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.
This change will apply to other AMD mainboards and
will be in a different commit.

Yes, we've seen what might be exceptions in the ramstage, and
it makes sense to handle them. This code is identical in structure
and operation to the previously committed payload exception handler,
though we reserve the right to change it as circumstances require.
The remaining question is whether we need it in romstage.

_RDMSR instruction loads the contents of a 64-bit model specific register (MSR)
specified in the ECX register into registers EDX:EAX.
The EDX register is loaded with the high-order 32 bits of the MSR
and the EAX register is loaded with the low-order 32 bits.
EDX:EAX = MSR[ECX]
So bit 49 will be contained in EDX register.
Buggy code instead of bit 49 (CombineCr0Cd) sets bit [49-32=17] (PfcStrideDis).
PfcStrideDis bit disables stride prefetch generation. This leads to memory
bandwidth loss.

Supermicro H8QGI board
After applying this change i observed huge memory bandwidth increase in tests
that runs on small amount of cores. But unfortunately it doesn't affect
overall bandwidth results on 4P system with 48 cores.
So i think that in this system leading limiting factor is
AMD HT-ASSIST feature (Probe filter).
But right now it is not working. System stucks in Linux boot. I have done
some experiments and figured out that stuck happens when system have cores in
compute unit (CU) other than CU with BSC (boot strap core).
CU is two cores (primary and seconary) that shares some things (L2 cache, FPU ...)
So with probe filter i can boot Linux with one (BSC)
or two (BSC + secondary core in its CU) cores.
And with this configuration i can see memory bandwidth on 1 core (or two cores)
close to original bios.

AMD f14: Add SPD read functions to wrapper code
- Move DIMM addresses into devicetree.cb
- Add the ASF init that used to be in the SPD read code into
mainboard_enable()
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.

Change:
This is the initial step for moving the AMD F14 & HUDSON1,2,3
SPD-read callout out of the mainboard directories and into
the wrapper. The next step is to update the platforms to use
this routine in BiosCallouts.c and to delete the code from the
mainboard directories. The DIMM addresses should be moved into
devicetree.cb.
If there are significant differences or reasons that the mainboard
needs to override this code, it's perfectly reasonable to keep using
the version in the mainboard, but this allows us to remove duplicated
code and simplify the mainboard directories.
Notes:
This started by duplicating what was in Persimmon, and was changed to
use the devicetree.cb structures. The ASF setup was also removed from
the persimmon copy (PMIO writes to 0x28 & 0x29) as that's not needed
for the SPD access and doesn't make sense to initialize here.
Significant cleanup and magic number reduction was done as well.
It is intended that this file will not be included in ramstage as
the DIMM init is all done in romstage.
This is similar to what was done for Parmer/Thatcher in commit
7fb692bd - http://review.coreboot.org/#/c/2190/
Fam15tn: Move SPD read from mainboards into wrapper
Yes, it would make sense to split this into two separate files
and move the SMBUS initialization and access into the southbridge
wrapper. Maybe that can come next.

I've used an operating system for over 10 years now that makes
UTF-8 easy. It's not called Linux or OSX.
When UTF-8 is needed, of course, then we can look again.
I can't think of a single redeeming feature of placing
it in the comment in this manner. It's certainy not
needed.
The inclusion of UTF-8 characters is inconvenient,
especially from a text terminal.
I don't really want to start using compose in
CROSH shell terminals on chromeos.
We might want to incorporate "no UTF-8" as a
commit filter. For now, get rid of these
characters.

Quoting Jens Rottmann [1]:
Nevertheless I still think this whole function is bogus for the E350M1. The
function assumes GPIO21 is wired to reset APU PCIe lane 0+1 (PCIe x8, port 4+5
as Coreboot/AGESA calls it), GPIO25 resets lane 2 (PCIe x4) and GPIO02 lane 3.
But the E350M1 has PCIe x16 i.e. probably APU lanes 0-3 bundled, completely
different layout. They could have chosen GPIO21 to force resets, or 25 - or
maybe 50 like on the Persimmon or any other they fancied or - and this is the
most probable - none at all. Having BiosGnbPcieSlotReset() toggle some GPIOs
without knowing what they do on the E350M1 (if anything at all) is nonsense.
In my opinion this whole function should just "return AGESA_UNSUPPORTED" and
good riddance.

These are essential functions for setting up the display port and
framebuffer, and also enable such things as aux channel
communications. We do some very simple initialization in romstage,
mainly set a GPIO so that the graphics is powering up, but the complex
parts are done in the ramstage. This mirrors the way in which graphics
is done in the x86 size.
I've added a first pass at a real device, and put it in the mainboard
Kconfig, hoping for corrections. Because startup is so complex,
depending on device type, I've created a 'displayport' device that
removes some of the complexity and makes the flow *much* clearer. You
can actually follow the flow by looking at the code, which is not true
on other implementations. Since display port is perhaps the main port
used on these chips, that's a reasonable compromise. All parameters of
importance are now in the device tree.

The MMC0 on google/snow can run in 8 bit mode. To simplify driver development,
we thought disabling it (using zero, which runs in 1-bit / 4-bit mode) may help.
However, after some experiments in payload drivers, setting pinmux to 8 bit mode
can still allow MMC to run in 1-bit / 4-bit mode, so it's pretty safe to enable
8 bit mode by default for better performance.
Verified to boot on google/snow, and got MMC0 working.

The power up default for the 14M_25M_48M_OSC switchable clock output ball of
the SB800 chipset is 14 MHz. sb800/bootblock.c changes this to 48 MHz,
which is the correct value for almost all SIOs. However, not for
'smscsuperio' (SMSC SCH311x), which needs the original 14 MHz and is not
configurable for other clock speeds. A wrong SIO clock supply results in
funny RS232 output (wrong bit speed) and non-working PS/2.
We could switch back to 14 MHz in the mainboard's romstage.c, but then the
clock frequency would change twice. The resulting short 48 MHz burst causes
a handful of rubbish characters on RS232 on every boot until the SIO clock
has stabilized again.
This patch skips the SB800 clock switch if the SIO Kconfig requests 14 MHz.
This does not affect any boards currently in the repository (yet).

The first reason for selecting the CPU model at compile time was a
multi-second pause if booting a single core Fusion T40R with MAX_CPUS=2.
Recent tests show the pause has disappeared, someone must have fixed it.
The second reason was me not knowing how to make a single vgabios image
work with two different PCI IDs. Many thanks to Martin Roth for educating
me! Quote:
"The way to make coreboot use the same vbios for different video device IDs
is through the map_oprom_vendev function. In family 14 it's in
northbridge/amd/agesa/family14/amdfam14_conf.c You would name your video
bios 1002,9802 in the config and all the other device/vendor IDs for the
family 14h processors will fall through the initial check for the video
bios and will get remapped to use that vbios. This only works if you're
initializing the vbios inside coreboot. I don't know if you're using
SeaBios as a payload, but if you are you can add the vbios to cbfs as
vgaroms/vbios.rom and the rom will always be initialized."
I'd like to add the vgabios is added as type 'optionrom' when Coreboot make
adds it, however to work with SeaBios it has to be added manually with
cbfstool and with type 'raw', or it will hang.

OK, this is tl;dr. But I need to write this in hopes we make
sure we don't put code like this into coreboot. Ever.
Our excuse in this case is that it was imported, not obviously wrong,
and easily changed. It made sense to get it in, make it work, then
do a cleanup pass, because changing everything up front is almost
impossible to debug.
The exynos code has bunch of base register values, e.g.
These are base addresses of things that look like a memory-mapped
struct. To get these to a pointer, they created the following macro,
which creates an inline function.
static inline unsigned int samsung_get_base_##device(void) \
{ \
return cpu_is_exynos5() ? EXYNOS5_##base : 0; \
}
And then invoke it 31 times in a .h file, e.g.:
SAMSUNG_BASE(clock, CLOCK_BASE)
to create 31 functions.
And then use it:
struct exynos5_clock *clk =
(struct exynos5_clock *)samsung_get_base_clock();
OK, what's wrong with this? It's easier to ask what's right with it. Answer: nothing.
I have a long list of what's wrong, and I may leave some things out,
but here goes:
1. the "function" can return a NULL if we're not on exynos5. Most uses of the code
don't check the return value.
2. And why would this function be running, if we're not on an exynos5? Why compile it in?
3. Note the cast everywhere a samsung_get_base_xxx is used.
The function returns an untyped variable, requiring the *user* to get two
things right: the cast, and the function invocation. One can replace that _clock(); with
_power(); in the code above, and they will be referencing the wrong registers, and
they'll never get an error!
We have a C compiler; use it to type data.
4. You're generating 31 functions using cpp each and every time the file is included.
The C compiler has to parse these each time. It's not at all like a simple cpp
macro which is only generated on use.
5. You can't tags or etags this code
6. In fact, any kind of analysis tool will be unable to do anything with this cpp magic.
That's only a partial list.
So what's the right way to do it? Just make typed constants, viz:
Or, since I expect people will want the lower case function syntax, I've left
it that way:
Now we've got something that is efficient, and we don't even need to protect with
any more.
Hence this change. We've got something that is type checked, does not require users to
cast on each use, will catch simple programming errors, can be analyzed with standard tools,
and builds faster.
So if we make a mistake:
struct exynos5_clock *clk =
samsung_get_base_adc();
We'll see it:
src/cpu/samsung/exynos5250/clock.c: In function 'get_pll_clk':
src/cpu/samsung/exynos5250/clock.c:183:3: error: initialization from incompatible pointer type [-Werror]
which we would not have seen before.
As a minor benefit, it shaves most of a second off the compilation.
