KVM implements the firmware interface for mitigating cache speculation
vulnerabilities. Guests may use this interface to ensure mitigation is
active.
If we want to migrate such a guest to a host with a different support
level for those workarounds, migration might need to fail, to ensure that
critical guests don't loose their protection.
Introduce a way for userland to save and restore the workarounds state.
On restoring we do checks that make sure we don't downgrade our
mitigation level.

Recent commits added the explicit notion of "workaround not required" to
the state of the Spectre v2 (aka. BP_HARDENING) workaround, where we
just had "needed" and "unknown" before.
Export this knowledge to the rest of the kernel and enhance the existing
kvm_arm_harden_branch_predictor() to report this new state as well.
Export this new state to guests when they use KVM's firmware interface
emulation.

voltage regulators values.
1. The voltage tables for configuring their registers mention range of
voltages: 0.750 V to 3.55 V,
2. The constrains in electrical specifications say output voltage range
to be different (buck7: 1.2 V to 1.5 V, buck8: 1.8 V to 2.1 V).
Adjust the ranges to match the electrical specifications to stay on the

not have effect.

Mali400 GPU hardware module is a standard hardware module integrated to
Exynos3210/4210/4412 SoCs, so it should reside under the "/soc" node.

The PMU module of Mali400 GPU is optional and it looks that it is not
present on Exynos4210, because any access to its registers causes external
abort. This patch removes "pmu" interrupt for Exynos4210 SoCs, so the
driver will skip the PMU module. This fixes following fault during kernel
boot:

(kernel_init) from [<c01010b4>] (ret_from_fork+0x14/0x20)
The PMU module seems to work fine on Exynos4412 SoCs, so the patch also
moves the interrupt definitions to exynos4210.dtsi and exynos4412.dtsi
respectively, to keep only the common part in exynos4.dtsi.

This is the other half of the hacky solution from commit f497ab6b4b
("ARM: dts: rockchip: Configure BT_HOST_WAKE as wake-up signal on
veyron"). Specifically the LPM driver that the Broadcom Bluetooth
expects to have (but is missing in mainline) has two halves of the
equation: BT_HOST_WAKE and BT_DEV_WAKE. The BT_HOST_WAKE (which was
handled in the previous commit) is the one that lets the Bluetooth
wake the system up. The BT_DEV_WAKE (this patch) tells the Bluetooth
that it's OK to go into a low power mode. That means we were burning
a bit of extra power in S3 without this patch. Measurements are a bit
noisy, but it appears to be a few mA worth of difference.
NOTE: Though these pins don't do much on systems with Marvell
Bluetooth, downstream kernels set it on all veyron boards so we'll do
the same.

With commit d8e8fd0ebf ("mtd: rawnand: denali: decouple controller
and NAND chips"), the Denali NAND controller driver migrated to the
new controller/chip representation.
Update DT for it.
In the new binding, the number of connected chips are described in
DT instead of run-time probed.
I added just one chip to the reference boards, where we do not know
if the on-board NAND device is a single chip or multiple chips.
If we added too many chips into DT, it would end up with the timeout
error in nand_scan_ident().
I changed all the pinctrl properties to use the single CS.

The arm-nommu DMA code supports DMA_ATTR_NON_CONSISTENT allocations, but
does not provide a cache_sync operation. This means any user of it
will never be able to actually transfer cache ownership and thus cause
coherency bugs.

Since the Linux 5.1 merge window we allow drivers to just set the
largest DMA mask they support instead of falling back to smaller ones.
But I forgot to remove a check that prohibits this behavior in the
arm DMA code, as it is rather hidden. There is not reason for this check
as the code will do the right thing for a "too large" DMA mask, so
just remove it.

Add nodes for GPU (Mali 400) to Exynos4210 and Exynos4412. Describe the
GPU as much as possible however still few elements are missing:
1. Exynos4210 bus clock is not described in hardware manual therefore
the IP gate clock was provided,
2. Exynos4412: Not sure what to do with CLK_G3D clock responsible for
gating entire IP block (it is now being disabled as unused),
3. Regulator supplies on Trats board.

The eMMC memory is supplied by LDO18 (PVDD_EMMC_1V8) and buck10
(PVDD_EMMCF_2V8), not by LDO10. The LDO10 (PVDD_PRE_1V8) supplies
instead VDDP_MMC pin of eMMC host interface and it is already marked as
always on.
This change only properly models the hardware and reflects in usage of
regulators. There is no functional change because:
1. LDO18 cannot be turned off (e.g. by lack of consumers) because in
off mode it is controlled by LDO18EN pin, which is pulled up by
always-on regulator LDO2 (PVDD_APIO_1V8).
2. LDO10 is marked as always on so removing its consumer will not have
effect.

Add the PMIC regulator suspend configuration to Arndale Octa board to
reduce power usage during suspend and keep necessary regulators on. The
configuration is based on vendor (Insignal) reference kernel and the
board datasheet. Comparing to vendor kernel, additionally turn off in
suspend all regulators controlled by external pin (LDO3, LDO7, LDO18 and
buck10).
This is purely for hardware description because board does not support
Suspend to RAM and the S2MPS11 driver does not support
"regulator-on-in-suspend" property.

The patch adds the following interfaces according the SMARC Spec 1.1
[1] and provided schematics:
- SMARC SPI0/1
Note: Since Kontron still uses silicon revisions below 1.3 they have
add a spi-nor to implement Workaround #1 of erratum ERR006282.
- SMARC SDIO
- SMARC LCD
- SMARC HDMI
- SMARC Management pins
Note: Kontron don't route all of these pins to the i.MX6, some are
routed to the SoM CPLD.
- SMARC GPIO
- SMARC CSI Camera
Note: As specified in [1] the data lanes are shared to cover the
csi and the parallel case. The case depends on the baseboard so
muxing the data lanes is not part of this patch.
- SMARC I2S
- SMARC Watchdog
Note: The watchdog output pin is routed to the CPLD and the SMARC
header. The CPLD performs a reset after a 30s timeout so we
need to enable the watchdog per default.
- SMARC module eeprom
Due to the lack of hardware not all of these interfaces are tesetd.
