If the CMOS is cleared or someone writes some random date/time
on purpose, the CMOS date register has a invalid date. This will
hurts some OS, like Windows 7, which hangs at MS logo forever.
When we detect that, we need to write a reasonable date in CMOS.
Alexandru Gagniuc:
Hmm, it would be interesting to use the date the coreboot image
was built and set that as the default date. At least until time
travel is invented.

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

With SandyBridge northbridge code, uma_memory_size was reset to

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.

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().

The ME device was being sent EOP and the PCI device hidden during
coreboot so it was not available in the SMI finalize step.
This also flips the PCI vendor/device dword around for the match.
Boot on Panther Point with serial and SMI debugging enabled and see
that ME EOP message is sent and the device is hidden at end of
U-boot and before the kernel loads.

The LPC bus normally allocates the range for legacy devices,
0-0x1000. Some devices on LPC are above that range and need to
be accounted for. Check the decode range settings for addresses
> 0x1000 and reserve them.

Events are logged for SMIs that trigger ACPI sleeps state
entry and when the power button press triggers an SMI such
as at the developer/recovery screens.
Generate ACPI sleep state events and power button
events and verify they show up in the log:

Unfortunately the drive strength values are very much board
specific and different between mobile and desktop so we don't
try to do any fancy detection here but let it be specified
directly in the devicetree.

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.

Read event routine didn't get the correct BIOS callout. So it could not get
the heap address. Then it would creat many warning in serial port.

The board has a marvell NIC, but the driver to disable NIC BIOS was adapted
from a Realtek 8168 driver. Rename to reflect the change.
Also hook up as driver, so coreboot can actually find it.
