Dave Frodin 0690eb2d90 Change to allow coreboot to use "add-payload" instead of "add" for payload images.
The current code does some argument manipulation to detect when a stage is being
added to cbfs. This same manipulation needs to be done when adding a payload.

Alexandru Gagniuc de415ebdd6 coreboot: Dump memory around problem area when encountering exception
When we encounter an x86 exception, we print the problem address, dump the
registers and die. This may not be sufficient information for debug. Also
dump the memory around the problem instruction. This has proven useful in
identifying memory issues, and DRAM burst reordering problems.

Stefan Reinauer 0db6820b10 Synchronize rdtsc instructions
The CPU can arbitrarily reorder calls to rdtsc, significantly
reducing the precision of timing using the CPUs time stamp counter.
Unfortunately the method of synchronizing rdtsc is different
on AMD and Intel CPUs. There is a generic method, using the cpuid
instruction, but that uses up a lot of registers, and is very slow.
Hence, use the correct lfence/mfence instructions (for CPUs that
we know support it)

Alexandru Gagniuc f88204e02b Add a capability for mainboard-specific posting.
Some mainboards have really nice capabilities for posting, beyond
simple POST cards. Further, some can not use a POST card. This
change defines a weak symbol (mainboard_post) that can be overridden
by a real mainboard_post function.

If, for example, you'd like to do something fancy before the payload starts,
you can add this to mainboard.c:

void mainboard_post(u8 value)
{
	switch(value){
		case POST_TIME_TO_PARTY: some_fancy_lights();
		break;
	}
}

Maybe the post function should be an entry in the device. We're beginning to over-use
weak symbols.

BUG=None

TEST=Build and boot a google chromebook. Observe that it still works. Use it to drive
some pretty lights.

Stefan Reinauer 57879c9bd1 Make the device tree available in the rom stage
We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
   compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
   the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
   romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage

We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.

So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
 #ifndef __PRE_RAM__
        .ops = 0,
 #endif
        .bus = &_dev7_links[0],
        .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
        .enabled = 0,
        .on_mainboard = 1,
        .subsystem_vendor = 0x1ae0,
        .subsystem_device = 0xc000,
        .link_list = NULL,
        .sibling = &_dev22,
 #ifndef __PRE_RAM__
        .chip_ops = &southbridge_intel_bd82x6x_ops,
 #endif
        .chip_info = &southbridge_intel_bd82x6x_info_10,
        .next=&_dev22
};

Stefan Reinauer 170d19c2ad x86emu: fix jump_near_IMM to handle DATA: flag correctly
Before (data flag ignored -> broken):
66                  DATA:
e944f1              JMP       1ff6

After (fixed):
66                  DATA:
e944f1ffff          JMP       00001ff8

This subtle difference in the length of decoded instruction meant
that the VBE call jumped to the routine setting AX=0x14F (VBE Failed)
instead of the routine that set AX=0x4F (VBE success).

The ability to run the same code in vm86 significantly aided the
debugging of this issue. Those X.org developers who would like to drop
vm86 better take special care towards _all_ vesa bugs, as those will
expose further issues.

zbao 9fd183efde AMD F15tn northbridge: Remove the misleading 0x100 from the limitk.
I dont known if missed something, but why an extra 0x100 was added to limit?
My board would get the wrong memory table entry 7f000000-7fffffff as RAM, which
is higher than TOM.
coreboot memory table:
0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES
1. 0000000000001000-000000000009ffff: RAM

6. 00000000a0000000-00000000afffffff: RESERVED

Ronald G. Minnich:
 I think someone who wrote the code was trying to round up the
next 0x100 boundary and did it incorrectly.
Here is code that would do it correctly:
limitk = ((resource_t)((d.mask + 0x00000ff) & 0x1fffff00)) << 9 ;

Zheng:
 Plus 0xFF is correct, but the d.mask take bit 0 as enable it.
This bit should be clear when we try to calculate the limitk.

With SandyBridge northbridge code, uma_memory_size was reset to
zero before variable MTRRs were set. This means MTRR setup routine
did not previously create a un-cacheable hole for uma.

Keep the behaviour that way, mmio_resource() has a prerequisuite that
the new region does not overlap with any cacheable ram_resource().

The result is not optimal setup in the number of used MTRRs, but
continue with this approach until MTRR algorithm is improved.

Kyösti Mälkki 6ff1d36a47 Intel and GFXUMA: fix MTRR and use uma_resource()
Commit 2d42b34003 changed the
variable MTRR setup and removed compensation of uma_memory_size in
the cacheable memory resources.

Since the cacheable region size was no longer divisible by a large
power of 2, like 256 MB, this caused excessive use of MTRRs.
As first symptoms, slow boot with grub and poor user response.

As a solution, register the actual top of low ram with ram_resource(),
and do not subtract the UMA/TSEG regions from it.

TSEG may require further work as the original did not appear exactly
right to begin with. To have UMA as un-cacheable, use uma_resource().

Recent changes in EC/Vboot/U-boot have completely broken
the logging of developer and recovery modes.

Recovery mode may not be in VBNV, so if that is zero and
yet we are in recovery mode then assume it is there because
the button/key was pressed.

Since there may not be any actual developer mode switch
we look if option rom is loaded and the system is not
in recovery mode and consider that as developer mode.

Duncan Laurie 55864eff92 ACPI: Add support for runtime config TDP down
The required power MSRs are mirrored in MCHBAR so
it is possible to configure TDP at runtime via ASL.

This adds the required fields and a set of methods to
configure "TDP down" and "TDP nominal".  It explicitly
does not support "TDP up" at the moment.

PSSS: method is added to assist in searching the _PSS
table for the appropriate entry that corresponds to the
desired max non-turbo ratio.

STND: Set TDP Down from Nominal.  This will limit CPU to
the TDP down configuration by sequencing the required
changes in the right order.

STDN: Set TDP Nominal from Down.  This will set the CPU
back to nominal configuration by sequencing the required
changes in the correct (reverse) order.

This does not introduce any functional changes and must
be paired with additional changes to be useful.

The current configured TDP can be checked to see that
the transition to/from a desired level is successful.

Duncan Laurie 0920915bca ELOG: Support GSMI in CPT/PPT southbridge SMI handler
In order to support the GSMI interface the SMI handler needs
to find and use the state save area from the same CPU that
initiated the SMI.  In this case it is a synchronous SMI
resulting form an IO write to port 0xB2.

To find the right CPU state save area iterate over the region
until the "IO Misc Info" field reports the expected value and
then proceed to use that state save area.

This is needed because the coreboot SMI handler only executes on
one core, and that core is non-deterministic.  It is likely that
the core executing the C SMM handler is not the same one that
actually did the IO write to 0xB2 and generated the SMI.

The GSMI parameter buffer is passed as a pointer to EBX in the
tate save area, and the GSMI command is extracted from EAX before
it is used as the return value.

This interface is tested by enabling CONFIG_GOOGLE_GSMI in the
kernel and generating events and verifying that they end up
in the event log.

Duncan Laurie 79bbbd9db3 ELOG: Add support for SMM and kernel GSMI driver
The linux kernel contains an SMI driver that was written by
me (Duncan) and upstreamed a couple years ago called GSMI.
This driver will format a parameter buffer and pass pointers
to this parameter buffer to the SMI handler.  It uses this to
generate events for kernel shutdown reasons:  Clean, Panic, Oops,
etc.

This function expects to be passed pointers into the SMM state
save area that correspond to the prameter buffer and the return
code, which are typically EAX and EBX.

The format of the parameter buffer is defined in the kernel
driver so we implement the same interface here in order to be
compatible.

GSMI_CMD_HANDSHAKE: this is an early call that it does to try
and detect what kind of BIOS is running.

GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that
has event type and data.  The kernel-specific events are
translated here and raw events are passed through as well which
allows any run-time event to be added for testing.

GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log.

First the gsmi driver must be enabled in the kernel with
CONFIG_GOOGLE_GSMI and then events can be added via sysfs
and events are automatically generated for various kernel
shutdown reasons.

These can be seen in the event log as the 'Kernel Event' type:

Stefan Reinauer be1ef2329e chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared Data
coreboot used to pass some information to u-boot in the coreboot table
and other information in a modified flat device tree. Since the FDT code
was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

Duncan Laurie 22935e1f43 CPU: Set flex ratio to nominal TDP ratio in bootblock
CPUs with configurable TDP will run the TSC at the max non-turbo
ratio for the maximum TDP value, which can cause issues if another
TDP is desired.  To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.

This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.

The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.

On some system with 1.8GHz CPU ensure that the kernel
detects the CPU speed as ~1800mhz rather than ~2300mhz:

> dmesg | grep "MHz processor"
[    0.004000] Detected 1795.801 MHz processor.

Duncan Laurie 7d2b81c18d ELOG: Add support for flash based event log
This is based around the SMBIOS event log specification but
expanded with OEM event types to support more specific and
relevant system events.

It requires flash storage and a minimum 4K block (or flash block
size) that should be allocated in the FMAP.

A copy of the event log is maintained in memory for convenience
and speed and the in-memory copy is written to flash at specific
points.

The log is automatically shunk when it reaches a configurable
full threshold in order to not get stuck with a full log that
needs OS help to clear.

ELOG implements the specification published here:
http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign

And is similar to what we use in other firmware at Google.
This implementation does not support double-buffered flash
regions.  This is done because speed is valued over the log
reliability and it keeps the code simpler for the first version.

This is a large commit and by itself it just provides a new
driver that is made available to coreboot.  Without additional
patches it is not very useful, but the end result is an event
log that will contain entries like this:

Duncan Laurie 77dbbac7e7 CPU: Add basic support for Nominal Configurable TDP
Ivybridge B0+ CPUs are capable of supporting multiple TDP levels.
This complicates the default case because now the registers that
were reporting max non-turbo ratio are reporting that value for
the highest possible TDP level.

For now this change just forces everything to use the Nominal TDP
values instead of the higher (or lower) levels.

- When building P-state tables, determine the P[1] (max non turbo)
ratio based on the Nominal ratio if available.
- Set the turbo activation ratio to the Nominal max ratio.
- Mirror the power level settings in new MCHBAR register after
they are written, which happens after BIOS_RESET_CPL is set.
- Set the current ratio to Nominal ratio at boot.

1) Verify that P-state table is generated properly with
P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12)

PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00
PSS: 1800MHz power 17000 control 0x1200 status 0x1200

2) Verify power limits in MCHBAR match PKG_POWER_LIMIT:

> rdmsr 0 0x610
0x800080aa00dc8088
> mmio_read32 0xfed159a4
0x000080aa
> mmio_read32 0xfed159a0
0x00dc8088

3) Verify turbo activation ratio is set to nominal ratio:

> rdmsr 0 0x64c
0x0000000000000012

4) Check that proper ratio was set at boot on one core only:

> grep 'frequency set to' /sys/firmware/log
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800

Previous patches implemented stack overflow checking for the APs.
This patch builds on the BSP stack poisoning patch to implement
stack overflow checking for the BSP, and also prints out maximum
stack usage. It reveals that our 32K stack is ridiculously oversized,
especially now that the lzma decoder doesn't use a giant 16K on-stack
array.

Break the stack checking out into a separate function, which
we will later use for the APs.

CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

To test failure, change the DEADBEEF stack poison value in c_start.S
to something else. Then we should get an error like this:
Stack overrun on BSP.Increase stack from current 32768 bytes
CPU0: stack from 00180000 to 00188000:Lowest stack address 00180000

Separate the act of loading from the act of starting the payload. This
allows us better error management and reporting of stack use. Now we
see:
CPU0: stack from 00180000 to 00188000:Lowest stack address 00187ad8

Tested for both success and failure on Link. At the same time, feel free
to carefully check my manipulation of _estack.

Stefan Reinauer 998f3a27be Cougar/Panther Point: Compile in ME7 and ME8 code at the same time
In the short term there might be devices with Sandy Bridge CPUs
on mainboards with Panther Point PCHes. While this configuration
option is perfectly valid, coreboot currently ties Sandy Bridge to
Cougar Point and Ivy Bridge to Panther Point. One occurence is in
the ME handling code.

To make coreboot most flexible, compile both ME handlers into
coreboot and decide at runtime which one to use.

When microcode storage in CBFS is enabled, the make system is supposed
to generate the microcode blob and place it into the generated ROM
image as a CBFS component.

The microcode source representation does not change: it is still an
array of 32 bit constants. This new addition compiles the array into a
separate object file and then strips all sections but data.

The raw data section is then included into CBFS as a file named
'microcode_blob.bin' of type 0x53, which is assigned to microcode
storage.

With this patch it is possible to use the smbus in ramstage. The
biggest part of the patch is a simple code split into a general
part (smbus.h) and the concrete users (early_smbus.c and cs5536.c).
After the switch from romstage to ramstage the smb base address
has changed, but that is no problem as the new base address is
stored in bar0 of the ISA bridge. It could also be read via msr,
but via PCI it is simpler. I used the following patch as

Ronald G. Minnich 305b19dd7a Remove code that enables/disables VMX in coreboot on chromebooks.
There are several reasons for this:
1. It's a core setting, not a platform setting, which is bizarre. But,
we disable vmx via an SMI, and that only happens on core 0.
Hence, the code did not correctly make the same settings on all cores-
one had them disabled, the others were in an unknown state.
When (e.g.) kvm started on a vmx-enabled core, then moved to a
vmx-disabled core, the processor would reset *very* quickly.
Changing this would be messy.

2. On the CPU on link, there is something about trying to set the lock
bit that is getting a GPF.

3. It's the wrong place and time to set it. Once controlled, they can't
be changed in the kernel. The kernel is what should control this
feature, not the BIOS, as we have learned time and time again. If
somebody is in as root and can start a VM, you have a lot more to
worry about than someone starting a guest virtual machine.

Ronald G. Minnich 79431f5f09 Make memalign print useful messages on failure
Brevity is the soul of wit, except for error messages;
then it's a sign of witlessness. I can say this because
this error message may be my fault, although it is lost
in the 20th century code base so who knows.

Anyway, when memalign dies, it's not a bad idea to have
a lot of information about what went wrong. So instead
of the terse single bit of "something failed" this patch
changes things to be a bit more useful.

Duncan Laurie da83a5f18e Fixes to enable RC6 on IvyBridge
- The unneeded poll on non-MT force-wake bit was timing out
and causing the gma_pm_init_pre_vbios() function to exit
early so it was not preparing PM registers properly.
I changed the gtt_poll() calls to not return on timeout
unless it can't proceed so we don't see half-initialized
registers.

- RC6+ (Deep Render Standby) is not working reliably so we
can just enable RC6 in the BIOS and let the kernel decide
if it wants to enable RC6+ later.

This Kernel message is new in kernel 3.4:
[drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

Kyösti Mälkki de3dde46fd AMD: Fix GFXUMA with 4GB or more RAM
Northbridge code incorrectly adjusted the last cacheable memory
resource to accomodate room for UMA framebuffer. If system had
4GB or more memory that last resource is not below 4GB and not
the one where UMA is located.

There are three consequences:

The last entry in coreboot memory table is reduced by uma_memory_size.

Due the incorrect code in northbridge code state.tomk,
end of last resource below 4GB, had not been adjusted.
Incrementing that by uma_memory_size diverts a region
possibly claimed for MMIO to RAM, as TOP_MEM is written.

Since the UMA framebuffer did not have IORESOURCE_CACHEABLE,
it was ignored from the MTRR setup and not set uncacheable.

The setting of TOP_MEM and TOP_MEM2, as well as all the MTRRs,
should be copied from BSP to all APs instead of deriving the data
separately for each Logical CPU.

Sven Schnelle 0fa50a1990 MPTAPLE: generate from devicetree.cb
This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.

Syntax in devicetree.cb:

ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>

The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

Ronald G. Minnich 97de28da8a PCI Type2 config must die
PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.

Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

The error message from romstage is annoying and misleading:
"Do not use global variables in romstage"

Because it can occur even when global variables are not used
in some circumstances, but also because it gives you only a rough
idea where to look. This change sucks but sucks less. We still don't
know which file the problem is in but at least we know if it is data
or bss.

Replace the error message with something that provides more information
and less guessing on the part of the script:
".bss is non-zero size in romstage which is not allowed -- global variable?"
or
".data is non-zero size in romstage which is not allowed -- global variable?"

To test: build coreboot as normal. It builds.
Add
char d[32];
to romstage.c and get the first error message; add
int x = 32;
to romstage.c and get the second.

- it uses only the BSP for determining the AP count, which is bad if
  there's more than one physical CPU, and CPUs are of different type

Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old

zbao ee8a9f6c55 Initializer of a static member in union.
It is just me or does anybody have the same build error without
this patch?
------
src/arch/x86/boot/acpigen.c: In function 'acpigen_write_empty_PTC':
src/arch/x86/boot/acpigen.c:347:3: error: unknown field 'resv'
specified in initializer

 initializer
src/arch/x86/boot/acpigen.c:347:3⚠️ (near initialization
 for 'addr.<anonymous>')
-------

Anyway, I believe at least this will cause warnings.
"resv" is a member of a union, not of acpi_addr_t. So it should be
wrapped by a brace in the initializer.

Vadim Bendebury 3b3a1a1ee6 Provide functions to access arbitrary GPIO pins and vectors
This change adds utility functions which allow to read any GPIO pin,
as well as a vector of GPIO pin values.

As presented, these functions will be available to Sandy Bridge and
Ivy Bridge systems only.

There is no error checking: trying to read GPIO pin number which
exceeds actual number of pins will return zero, trying to read GPIO
which is not actually configured as such will return unpredictable
value.

When reading a GPIO pin vector, the pin numbers are passed in an
array, terminated by -1. For instance, to read GPIO pins 4, 2, 15 as a
three bit number GPIO4 * 4 + GPIO2 * 2 + GPIO15 * 1, one should pass
pointer to array of {4, 2, 15, -1}.
