by ensuring the device is held in reset with clocks gated
until slot power is enabled and coreboot is about to
initialize devices.
Sequence per NVMe port:
1) pre-mem: disable CLKREQ#, assert PERST#, PWREN=0
2) BS_PRE_DEVICE exit: PWREN=1, enable CLKREQ# native,
keep PERST# asserted
3) BS_DEV_INIT_CHIPS entry: deassert PERST#

Currently, mainboards that do not support Google TPM must manually
define stubs for chromeos_device_branded_plus_hard() and
chromeos_device_branded_plus_soft() to satisfy the linker.
Move these stubs into vendorcode/google/chromeos/chromeos.h as static
inline functions when CONFIG(TPM_GOOGLE) is disabled. This reduces
code duplication and allows the removal of redundant stub definitions
in the ptlrvp mainboard.

Introduce EC_GOOGLE_CHROMEEC_LED_CONTROL to allow boards to opt-in to
manual LED/lightbar synchronization. This ensures that the AP firmware
can coordinate the lightbar state with boot animations or specific
power states (like critical battery alerts) without forcing the logic
on all ChromeEC-based platforms.
On Bluey, the lightbar logic is refactored into a helper function
`platform_init_lightbar()` to improve readability and is now gated
by the new Kconfig. Similar gating is applied to Fatcat's romstage.
Summary of changes:
- Add EC_GOOGLE_CHROMEEC_LED_CONTROL Kconfig option.
- Bluey: Refactor lightbar init into a helper and gate by Kconfig.
- Fatcat: Gate early lightbar initialization by Kconfig.

Add launch_charger_applet() to handle the system state when booting
in off-mode charging or low-power modes with a charger present.
Key features:
1. Monitoring: Periodically checks battery current (I-current) via
SPMI/PMIC registers.
2. Event Handling: Detects and clears EC power button and lid events.
If a manual power-on event is detected, the system triggers a
full board reset to ensure a clean boot to the OS (preventing
firmware state conflicts like ADSP-lite vs ADSP).
3. Shutdown: If the charger is removed, it signals the EC via
off-mode heartbeat and initiates an AP power-off.
BUG=b:439819922
BRANCH=None
TEST=Verified that the device enters the charging loop when plugged
in while off, and transitions to a full boot when the power button
is pressed.

Implement google_chromeec_offmode_heartbeat() to wrap the
EC_CMD_ENABLE_OFFMODE_HEARTBEAT host command.
This allows the AP to signal the EC to maintain the power state
required for off-mode UI (such as the charging applet) during
shutdown or low-power transitions.
BUG=b:439819922
BRANCH=none
TEST=Build and verify that the charger applet can successfully
call this function to enable heartbeat signaling.

Add the SoC hook to initialize SPI TPM decoding. Without the additional
programming an attempt to talk to SPI TPM hangs the platform when the
TPM_MEASURED_BOOT_INIT_BOOTBLOCK is set. If TPM is initialized in
ramstage, the OpenSIL programs the SPI TPM decoding properly and the
issue is not observed.
TEST=Select TPM_MEASURED_BOOT_INIT_BOOTBLOCK and enable
TPM_MEASURED_BOOT on Gigabyte MZ33-AR1, and observe the platform does
not hang in bootblock.
