Angel Pons 8376f2d4b2 mb/asrock/b85m_pro4: Make VGA work on Linux
Currently, having libgfxinit try to enable VGA will result in a hang.
On the Asrock B85M Pro4, DDI E (VGA) was not being enabled in coreboot,
so it did not hang. However, this renders Linux's i915 driver unable to
use VGA at all. In absence of monitors with digital inputs, this is bad.

To work around this problem, mark DDI E as enabled, and comment out VGA
from gma-mainboard.ads for the time being. This allows one to use a VGA
monitor, even if it only works after Linux drivers have taken over.

Port commit d7b88dcb (mb/google/x86-boards: Get rid of power button
device in coreboot) to AMD AGESA Hudson boards.

No idea, if this is correct for the two laptops. The Lenovo G505s also
incorrectly defines two power buttons.

    [    0.911423] input: Power Button as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0C:00/input/input1
    [    0.911434] ACPI: Power Button [PWRB]
    [    0.911493] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2
    [    0.912326] ACPI: Power Button [PWRF]

If the generic power button device is needed, the POWER_BUTTON flag
should be set in FADT.

The GPE ACPI code seems to originate from commit 806def8c (I missed the
svn add on r3787. These are the additional files., Add AMD dbm690t ACPI
support.), and was copied over.

Mathew King 071182ade3 ec/google/wilco: Always use current value of battery status bit
According to the Wilco EC spec the BTSC bit of PWSR is always cleared
when PWSR is read so that battery status change events are only
triggered one time. Testing of the Wilco EC has verified this behavior.
This changes the way in which the battery status change bit is used from
checking the bit state against the previous value to always issuing a
battery event when the BTSC bit is set. The other bits in PWSR indicate
state directly and do not behave like the BTSC bit.

Edward O'Callaghan 7c52283f78 chromeos/cr50_enable_update.c: Modify recovery flow for cr50
Enable Cr50 update in recovery mode, so that we can at least still
update the process for most cases (that an update is pending in recovery
mode is not impossible but should be unlikely in the field).

Leave manual recovery unaffected so at least that would still work even
if Cr50 wedges in a weird way that it thinks it has an update on every
boot or something.

Setting the recovery_reason to VB2_RECOVERY_TRAIN_AND_REBOOT allows the
update to be applied.

Thanks to Julius Werner for the suggested fix.

GENERIC_SPD_BIN assumes that the SPDs are all placed in mainboard and
have .spd.hex as the suffix. Disable GENERIC_SPD_BIN for dedede as it
already provides its own rules for SPD inclusion. In follow up
changes, GENERIC_SPD_BIN can be re-enabled by updating gen_spd.go tool
to use similar suffixes and allowing different paths to be provided
for SPD by mainboard.

This change adds mem_list_variant.txt that contains the list of

In the final change of the series, all dedede variants will be

Differences in auto-generated SPD from current SPD are as follows:

                                 density per die is 16Gb.
6        0x90        0x04        1 die in package and 2 channels per
                                 die.
9        0x40        0x00        Unused by MRC.
19       0x0F        0xFF        As per JEDEC spec, tckMax should be
                                 100ns. So, value should be 0xFF as
                                 per datasheet.
123      0x00        0xE5        Fine offset for taa. Expected value
                                 is 0xE5 as per datasheet.

                                 datasheet tckMin is 0.468ns. So, this

Additionally, manufacturer name bytes are set to 0.
