help
The platform/ec Zephyr module allows some code from the
existing Chromium OS EC project to be "shimmed" into Zephyr. With
this it is possible to use the existing code base within Zephyr.
Once we manage to get a platform fully running with Zephyr we will
progressively upstream components and turn off the shim for each
one until eventually all code is on the Zephyr side.

config PLATFORM_EC_ACPI
bool "Advanced Confiugration and Power Interface (ACPI)"
default y if AP_X86 && PLATFORM_EC_HOST_INTERFACE_ESPI
help
Enable the Advanced Configuration and Power Interface (ACPI) in the
EC. ACPI is a standard interface to the Application Processor (AP)
that abstracts the hardware specific details for controlling and
managing the board.
This includes interfaces for monitoring or controlling features,
including:
keyboard backlight
fan speed
temperature sensors
charging properties
device orientation (tablet or laptop mode)
https://uefi.org/sites/default/files/resources/ACPI_Spec_6_4_Jan22.pdf
config PLATFORM_EC_AP_RESET_LOG
bool "Enable the Application Processor reset log"
depends on PLATFORM_EC_HOSTCMD_GET_UPTIME_INFO
default y if PLATFORM_EC_POWERSEQ
help
Enable logging of AP reset events. This information is provided in
response to the EC_CMD_GET_UPTIME_INFO host command.
config PLATFORM_EC_BACKLIGHT_LID
bool "Control the display backlight based on the lid switch"
depends on PLATFORM_EC_HOSTCMD
default y
help
Support controlling the display backlight based on the state of the
lid switch. The EC will disable the backlight when the lid is closed.
This option enables the EC_CMD_SWITCH_ENABLE_BKLIGHT host command,
which allows the AP to override the backlight setting until the next
change in the lid state.
config PLATFORM_EC_BACKLIGHT_LID_ACTIVE_LOW
bool "Control for the display backlight is active low"
depends on PLATFORM_EC_BACKLIGHT_LID
help
Support controlling the backlight with an active low GPIO signal.
This config option expects a GPIO_ENABLE_BACKLIGHT_L defined.
config PLATFORM_EC_BOARD_RESET_AFTER_POWER_ON
bool "Work around H1 reset issue"
help
Enable this if H1 resets the EC after power-on. This is needed so the EC
can delay its start-up until the reset happens. Without this option
the EC starts up, performs some amount of processing and then gets a
reset that it is not expecting.
config PLATFORM_EC_BOOT_NO_SLEEP
bool "Disable deep sleep after boot"
default y if !ZTEST
help
Disable deep sleep for PLATFORM_EC_BOOT_NO_SLEEP_MS after boot.
config PLATFORM_EC_BOOT_NO_SLEEP_MS
int "No deep sleep after boot duration"
default 15000
help
Duration for PLATFORM_EC_BOOT_NO_SLEEP in ms.
config PLATFORM_EC_WAIT_RESET_CYCLES_PER_ITERATION
int "CPU execution cycle per iteration for waiting the H1 reset"
default 4
depends on PLATFORM_EC_BOARD_RESET_AFTER_POWER_ON
help
This options specifies the number of CPU execution cycles per delay
loop iteration, while waiting for the H1 to reset.
config PLATFORM_EC_PREINIT_HW_CYCLES_PER_SEC
int "CPU power up clock cycle per second"
default 100000000
depends on PLATFORM_EC_BOARD_RESET_AFTER_POWER_ON
help
This option specifies the frequency (in Hz) of the CPU core when
coming out of a power on reset.
config PLATFORM_EC_BRINGUP
bool "Enable early bringup debugging features"
help
Enable the CONFIG_BRINGUP platform/ec configuration option,
turning on a variety of miscellaneous early bringup
debugging features.
These features include:
- The device will not power on when the EC starts. The
power button will need to be pressed, or the "powerbtn"
command issued.
- Enable power signal logging, showing relative timestamps
for each power signal change.
- And more! You can search the codebase for CONFIG_BRINGUP
to see all of the features this flag will toggle.
config PLATFORM_EC_CHIPSET_RESET_HOOK
bool "Provide a hook for when the AP resets"
default y
help
Enables support for the legacy HOOK_CHIPSET_RESET hook.
This can be used by code that needs to run before a programmatic
reset actually happens. Note that these hooks don't run with a
cold reset, only when the AP decides to reset itself.
The hook is shimmed into the AP callback API, so you can
set up a ap_power_ev_callback with the AP_POWER_RESET
event to call a handler when the AP is about to be reset.
config PLATFORM_EC_CHIPSET_RESUME_INIT_HOOK
bool "Enable chipset resume-init and suspend-complete hooks"
help
Enables support for the HOOK_CHIPSET_RESUME_INIT and
HOOK_CHIPSET_SUSPEND_COMPLETE hooks. These hooks are usually used to
initialize/disable the SPI driver, which goes to sleep on suspend.
Require to initialize it first such that it can receive a host resume
event, that notifies the normal resume hook.
The legacy hooks are shimmed into the AP callback API, so
a ap_power_ev_callback can be set up with the events
AP_POWER_RESUME_INIT and AP_POWER_SUSPEND_COMPLETE to
call a handler when these events are triggered.
config PLATFORM_EC_CHIP_INIT_ROM_REGION
bool "Enables the use of a dedicated init ROM region"
help
Enable this flag if the board has a `.init_rom` region. This will
activate routines in `init_rom.h` to access objects in this region.
config PLATFORM_EC_CONSOLE_CMD_HCDEBUG
bool "Console command: hcdebug"
default y
depends on PLATFORM_EC_HOSTCMD
help
Enable the 'hcdebug' console command. This comamnd is used to change,
at runtime, the amount of debug generated by the host command
processing.
hcdebug [off | normal | every | params]
See PLATFORM_EC_HOSTCMD_DEBUG_MODE for more detail.
config PLATFORM_EC_CONSOLE_CMD_IRQ
bool "Console command: irq"
depends on TRACING_ISR && TRACING_USER
help
Enable the "irq" console command. This command lists the number of
IRQ calls.
config PLATFORM_EC_CONSOLE_CMD_MEM
bool "Console command: md, rw"
default y
help
Enable memory related console commands.
md - dump memory values
rw - read or write in memory
config PLATFORM_EC_CONSOLE_CMD_SLEEPMASK
bool "Console command: sleepmask read"
default y if PM
help
Enable the 'sleepmask' console command. This command is used to
display the state of the sleep mask, which controls whether the EC
chip is allowed to enter deep sleep states to save power.
config PLATFORM_EC_CONSOLE_CMD_SLEEPMASK_SET
bool "Console command: sleepmask set"
depends on PLATFORM_EC_CONSOLE_CMD_SLEEPMASK
default y
help
Enable changing the state of the current sleep mask.
sleepmask on - Sets the SLEEP_MASK_FORCE_NO_DSLEEP bit in the
sleep mask, preventing the system from entering
sleep.
sleepmask off - Clears the SLEEP_MASK_FORCE_NO_DSLEEP bit in the
sleep mask. The system may enter deep sleep
depending on the state of other mask bits.
sleepmask <value> - Sets the sleepmask to <value>, overriding all
bits with the specified value.
config PLATFORM_EC_CONSOLE_CMD_S5_TIMEOUT
bool "Console command: s5_timeout"
default n
help
This command allows the user to specify a time to remain in S5 before
dropping to G3, in order to help power testing.
config PLATFORM_EC_CONSOLE_CMD_SHMEM
bool "Console command: shmem"
default y
help
This command prints basic information about the EC shared memory,
located at the top of RAM, above all RAM symbols: total size, bytes
used and the maximum number of bytes that have been used since
the EC started running.
config PLATFORM_EC_CROS_FWID_VERSION
bool "Include CrOS FWID version"
default n
help
Include Chrome OS FWID in version output. The CrOS FWID will be common
across OS, AP firmware and EC firmware when built together.
config PLATFORM_EC_DEBUG_ASSERT
bool "Enable assertion failures"
default y
help
Assertion failures are used to flag conditions which should not occur
and thus indicate the software is unable to continue execution. This
option can be disabled so that the assert() macro becomes a NOP. In
this case, execution will continue but the results are unpredictable.
Messages are of the form:

help
Enable support for collecting and reporting panic information,
caused by exceptions in the EC. This can be the result of a watchdog
firing, a division by zero, unaligned access, stack overflow or
assertion failure.
The panic information is made available to the AP via the
EC_CMD_GET_PANIC_INFO host command and a 'panicinfo' console command
config PLATFORM_EC_PORT80

help
Enable support for a real-time clock. Typically this is available
on-chip in the EC. It provides a way to track the passage of time
in terms of second and minutes. Once set, and provided that it has a
suitable power source, it should be able to keep reasonably accurate
time over a period of days and weeks.
The starting EC clock is typically set by the AP, since it has access
to the outside world and can often obtain the current time when
desired.

System should remain unlocked even if write protect is enabled.
NOTE: This should ONLY be defined during bringup, and should never be
defined on a shipping / released platform.
When defined, CBI allows ectool to reprogram all the fields.
Normally, it refuses to change certain fields. (e.g. board version,
OEM ID)
Also, this enables PD in RO for TCPMv2.

help
Enables Early Firmware Selection v2 (EFS2) verified boot. When booting
a Chromium OS image we're actually packing both an RO image and an RW
image into flash. The RO image is loaded first. EFS2 runs at boot and
verifies the integrity of the RW image by sending a hash of the image
to the Google Security Chip (GSC). Once the GSC verifies the hash,
EFS2 calls sysjump and reboot the EC using the RW image.
config PLATFORM_EC_VBOOT_HASH
bool "Host command: EC_CMD_VBOOT_HASH"
depends on PLATFORM_EC_HOSTCMD
default y
help
Allows the AP to request hashing functions from the EC.
Verified boot can update the EC's read/write code when it detects
that it is an incorrect version. It detects this by asking the EC to
hash itself. If the hash is incorrect, new code is write to the EC's
read/write area.
config PLATFORM_EC_VSTORE
bool "Secure temporary storage for verified boot"
default y
help
Enable support for storing a block of data received from the AP so it
can be read back later by the AP. This is helpful since the AP may
reboot or resume and want the data early in its start-up before it
has access to SDRAM.
There are a fixed number of slots and each can hold a fixed amount of
data (EC_VSTORE_SLOT_SIZE bytes). Once a slot is written it is locked
and cannot be written again unless explicitly unlocked.
Stored data is preserved when the EC moved from RO to RW.
config PLATFORM_EC_VSTORE_SLOT_COUNT
int "Number of slots"

When the AP is attached to the EC via a serialized bus such as I2C or
SPI, it needs a way to minimize the length of time an EC command will
tie up the bus (and the kernel driver on the AP). If this config is
defined, the EC may return an in-progress result code for slow
commands such as flash erase/write instead of stalling until the
command finishes processing, and the AP may then inquire the status
of the current command and/or the result of the previous command.
