4ecdf78793 g: allow to select the default USB PHY at startup.
When (USB-)resuming from deep-sleep, ensure that we avoid switching back
and forth the selected USB PHY at boot, in order to avoid having a
short disconnection at resume.
To achieve this, allow the board configuration to select the PHY it is
really using with the CONFIG_USB_SELECT_PHY_DEFAULT configuration
variable, still keep the default USB_SEL_PHY1 as before.

375b607761 npcx: system: Add support for npcx7 series ec
This CL implements two methods for hibernating on npcx7 ec. One is using
PSL (Power Switch Logic) circuit to cut off ec's VCC power rail. The
other is turning off the power of all ram blocks except the last code
ram block. In order to make sure hibernate utilities are located in the
last code ram block and work properly, we introduce a new section called
'after_init' in ec.lds.S.

We also moved the hibernate utilities, workarounds for sysjump and so on
which are related to chip family into system-npcx5/7.c. It should be
easier to maintain.

It also includes:
1. Add CONFIG_HIBERNATE_PSL to select which method is used on npcx7 for
   hibernating.
2. Add new flag GPIO_HIB_WAKE_HIGH to configure the active priority of
   wake-up inputs during hibernating.
3. Add DEVICE_ID for npcx796f.

allows us to initialize other components (e.g. USB) while the

After CONFIG_RWSIG_JUMP_TIMEOUT, the EC will jump to the RW section
if no action is taken by the AP (such as a forced request to jump
to RW, or starting an update).

Note: This comes with a ~36ms boot time regression, as other code
gets to run before verification starts.

ca0e826859 common/rollback: Add support for rollback protection
Implement actual rollback protection. First, we add a new field
in the version structure, which is an incrementing integer
(we'll start by shipping images with version 0, and gradually
increase the number as required). This allows us to release
new versions of the EC without necessarily bumping the rollback
protection.

For the rollback protection block itself, it contains 2 sub-blocks
of equal size (normally, 2k), that are individually erasable.
The rollback code looks at both, and takes the most restrictive one
to determine the desired rollback minimum version. The blocks
are also allowed to be erased (full of 1's), in which case the
rollback minimum version is assumed to be 0.

We also add an FMAP entry, in case we later decide to allow the
signer to increment the rollback version.

Also note that, like any version_data struct change, this change
breaks compatibility between old and new RO/RW.

Follow-up code will take care of auto-updating the rollback block
as required, and properly manage block protection.

fa1a7c49f7 battery: Allow BATTERY_LEVEL_NEAR_FULL to be defined by board
Allow the board to override the hardcoded 97% value for reporting to
the host (and controlling LED behavior) when the battery is "near full".

When enabling "discharge on ac" with a full battery the battery stops
taking a charge until it reaches ~94% SOC (the actual value is not set
but rather comes from a smart battery status bit) but the user will see
the device as discharging between 97% and 94%.

The host side view can be worked around with a powerd preference.
The LED behavior is all inside the EC, so you end up with the LED showing
discharging when it should not.

If we allow the board to override this to 94% then the LED and host
behavior is consistent.

We call enable/disable_sleep at suspend/resume, to make
sure the EC stays awake when USB is connected and active.

We also call clock_enable/disable_module, which is stubbed on
stm32f0, but can be used on other devices in the family.

This also fixes interrupt handling in usb_interrupt, by only
clearing interrupt bits that were handled instead of resetting
them all, which is racy, and can potentially lead to issues
if reset comes soon after a resume event.

83cf8d0a7a flash: Add EC_FLASH_PROTECT_RW_[AT_BOOT|NOW] flags
The idea of this flag is to be able to protect/unprotect only the
RW portion of the flash. In the (usual) case where ALL=RO+RW, with
no other region, this makes no difference compared to the existing
EC_FLASH_PROTECT_ALL_* flag, and this flag may not be supported.

This is necessary for futher work, where a ROLLBACK region is added,
so that RW/ROLLBACK can be protected/unprotected individually.

4ff544a573 Add host command to get PD chip information
This patch adds a host command to get PD chip info.

For PS8751, tcpci_get_chip_info will fail if the chip is in
low power mode. It can be woken up by reading a random register
first then wait for 10ms.

This code doesn't have the wake-up read to avoid 10ms delay.
Instead, we call this function immediately after the chip is
initialized because it'll gurantee the chip is awake.

Once it's called, the chip info will be stored in cache, which
can be accessed by tcpc_get_chip_info without worrying about
chip states.
