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.

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:

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

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

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

especially now that the lzma decoder doesn't use a giant 16K on-stack

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:

for this to work, we need Ivy Bridge MRC and coreboot configured

We accomplish this goal by getting rid of the huge auto array in the
ram stage. This will in turn let us reduce CONFIG_STACK_SIZE.
We have to leave it on the stack in CAR as that's the simple way to
keep it private. It does not matter then as there is only one core
that is active.

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

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.

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

when an address is desired.
Set the stack to a non-zero value which is also (by testing)
a pointer which will crash coreboot if used. This poisoning

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.

Because it can occur even when global variables are not used

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

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.

Without that fix the debugging is harder because the person debugging

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}.

- Move mrc cache handling to separate file
This enables us to handle the MRC cache from ramstage,
where we can write the flash safely (eg. to update the
cache).
Also teach it to lookup the current MRC cache from CBMEM,
as the original data block isn't available anymore.
After all the preparations, finally write to the SPI
as necessary. It's a simple round robin wear levelling
that erases the entire MRC cache region when it's full

Another bug in the Intel microcode update code that existed since we switched
to LinuxBIOSv2 in 2004:
The inline assembly code that reads the CPU revision from an MSR after running
cpuid(1) trashes registers EBX and ECX. Only ECX was mentioned in the clobber
list. C code running after this function could silently access completely wrong
data, which resulted in the wrong date being printed on microcode updates (and
potentially other issues happening until the C code writes to EBX again)

No part of ChromeOS seems to use the debug header description, so drop
it to make sure it does not get copied around wrongly.

If microcode.c is built by romcc, this indicates that we are running
microcode updates in the bootblock (e.g. before enabling cache as ram).
In this case we did not enable any consoles yet, so we don't output
anything.
This patch removes inclusion of the unnecessary console/console.h for
that case, which was breaking with certain configurations.

It is important to have the system configuration reported as early as
possible to have a better idea what exact chipset the platform is
running with.
This change adds code to have an early coreboot module report the CPU
and PCH information. CPU info includes the 32 bit feature information
word, the symbolic processor brand string, and information about some
features support, as obtained through CPUID instructions.
The PCH information includes the symbolic device name and PCI device
version.

The current early PM setup that attempts to configure dynamic clock
gating relies on PCIe functions to be enabled that may not be.
Instead of reading port 0 or 4 directly to determine the link width
use the register that refelects the soft strapping options as this
will always be available.
Also add a clear register assignment and break for port 0 in the
switch statement instead of falling through to port 4 as that could
end up setting the slot power limit based on port 4 values instead
of based on port 0.
register 0xE1=0x3f and all other root ports should have 0xE1=0x03.
When port 0 and 4 are disabled they will have 0xE1=0x3C before
being disabled by the pch enable handler.
