Duncan Laurie 836db26b1c ACPI: Zero pstate/cstate control values in FADT
If these values are non-zero then the kernel will issue
an SMI for each core (cstate) and package (pstate).

Since we don't do anything with these SMI callbacks we
can avoid taking the extra SMIs at boot time by zeroing
these fields.

Marc Jones f5a11aa82f Initialize the VMX MSR
The VMX MSR may come up with random values and needs to be
initialized to zero. This was done incorrectly in finalize_smm.
It must be done on a per core basis in the general CPU init.
This touches all Sandybridge and Ivybridge configs.

Marc Jones 5986edadff Revert "Remove code that enables/disables VMX in coreboot on chromebooks."
The MSR for VMX can start with a random value and needs to be
cleared by coreboot. I am reverting this change, as
it handles almost everything and doing a follow-on change to fix
the improper clearing of the MSR.

Vadim Bendebury 0a1c2d62fa Prevent inclusion of tsc.h when not needed
src/include/timestamp.h is an interface describing timestamp storage
in coreboot. Exporting this interface is complicated by inclusion of
tsc.h which is needed only for the API and is not used in structure
definitions. Including this dependency only when needed fixes the
problem.

Duncan Laurie 4b1610d766 RTC: Don't clear pending interrupt in resume path
The linux kernel relies on the RTC reporting pending interrupts if
the RTC alarm was used to wake the system.  If we clear these flags
here then the rtc-cmos driver in the kernel will think that no
interrupts are pending and will not re-start the timerqueue to
handle the alarm timerqueue node.

This flag doesn't exist in SMM but the rtc code is compiled there.
Since rtc_init() is not called by SMM it is guarded with an ifdef.

I performed several thousand suspend/resume cycles without seeing
an issue where hwclock was unable to read from /dev/rtc.  There
still is a potential kernel issue where the timerqueue can stall
but this makes that much less likely to happen on resume.

Until now, the MRC cache position and size was hard coded in Kconfig.
However, on ChromeOS devices, it should be determined by reading the

look for sections.

This will also be needed on some partner devices where coreboot will
have to find the VPD in order to set up the device's mac address
correctly.

The MRC cache implementation demonstrates how to use the FMAP parser.

Vincent Palatin fa90fd4f2f rtc: erase CMOS memory after power failure
When a power failure happens on the RTC rail, the CMOS memory (including
the RTC registers) is filled with garbage.
So, we erase the full first bank (112 bytes) and we reset the RTC date
to the build date.

To test, disconnect the CMOS battery to produce an RTC power
failure, then boot the machine and observe the RTC date is the build
date using "cat /sys/class/rtc/rtc0/date"

On Panther Point PCH (and maybe cougar point), when some of the register

There are probably undocumented features implemented behind those bits.
Let's reset register D to a known state to ensure we get the expected
RTC behavior.

Stefan Reinauer b6e1237978 Move global variable check to Makefile
Our linker script for romstage checks for global variables and
makes the build fail if there are any (on non-AMD systems).
This is great, but having the build fail without any indication
which variables are global is not very useful.

Moving the check to the Makefile allows us to let the linking stage
succeed and reveil which variable names end up in the data and bss
sections of the binary.

To test, add "int foo;" as the first line in src/mainboard/samsung/lumpy/romstage.c
and build coreboot for Lumpy. See the build break the following
way:

Siyuan Wang 6f05c2eb59 AMD rd890 late.c: Don't enable PCIe ports after PCIe init.
PCIE devices are detected and initialized by the AMD PCIe init functions,
which is in cimx rd890. The parameters are read from devicetree.cb before PCIe init.
Now, all bridges and devices are trained on the device 0.0 enable.
After PCIe init, the PCIe ports with devices are on and the PCIe ports
without devices are off. so resources may be allocated correctly
during the rest of the PCI scan.

But if the devicetree was being used to enable/disable devices after initialization,
the problems would arise. Take a look at the serial log:

do_pci_scan_bridge for PCI: 00:02.0
PCI: pci_scan_bus for bus 01
PCI: pci_scan_bus returning with max=001
do_pci_scan_bridge returns max 1
do_pci_scan_bridge for PCI: 00:03.0
PCI: pci_scan_bus for bus 02
PCI: pci_scan_bus returning with max=002
do_pci_scan_bridge returns max 2
do_pci_scan_bridge for PCI: 00:04.0
PCI: pci_scan_bus for bus 03
PCI: pci_scan_bus returning with max=003
do_pci_scan_bridge returns max 3

PCI bridge 02.0, 03.0 and 04.0 are not inserted devices, but these bridges
are still scanned. This is not correct.

Siyuan Wang fa678bb87f AMD agesa family15: PCI domain should scan bus from 0x18.0
There are four mainboards using agesa family15 code:
Supermicro h8scm and h8qgi, Tyan s8226 and AMD dinar.
All of these boards' PCI domain starts from 0x18.0. Take h8scm as
an example, PCI devices from 0.0 to 0x14.5 is under 0x18.0.
Now, the PCI domain's scan bus function stats from 0.0. This would
result to the PCI devices be scanned twice. Because when the function
run to device 18.0, it would scan from 0.0 again.
This issue would result to 2 problems:
1) PCI device may be assigned two different PCI address.
   If this happenned on VGA device, coreboot maybe not load
   vga bios correctly.
2) coreboot initializes rd890's IO APIC twice.
So this patch scans from 0x18.0 and could resolve the problems above.
