config PLATFORM_EC_CONSOLE_CHANNEL
bool "Console channels"
depends on CONSOLE
default y
help
Make it possible for console to be output to different channels that
can be turned on and off. Channels are organized by functional area
such as "charger", "motionsense", "usbpd" and others.
This is useful as a developer convenience when the console is crowded
with messages, to make it easier to use the interactive console.
The `chan` console command with no arguments shows all available
channels.
FAFT and servod also use this feature.
Boards may #undef this to reduce image size.
# Adjusted to the longest print message from the timer_info command

# Some boards may need to increase the size, depending on the amount of output

# enabled. Increase the TX buffer size to workaround the hang when the help

help
Enable the EC_CMD_CONSOLE_SNAPSHOT and EC_CMD_CONSOLE_READ
host commands, used for reading the EC console from the AP.
if PLATFORM_EC_HOSTCMD_CONSOLE
config PLATFORM_EC_HOSTCMD_CONSOLE_BUF_SIZE
int "Console buffer size"
default 4096
help
The EC will use a circular buffer to store bytes outputted
to the console for the AP to read. This changes the maximal
number of bytes from the console output which can be saved.
Choosing a power-of-two for this value is optimal, as
modular arithmetic is used.

config PLATFORM_EC_CONSOLE_USES_PRINTK
bool "Console uses printk"
depends on CONSOLE
help
Implement zephyr_print using printk for all cases instead
of using shell_fprintf for non-ISR uses in
shim/common/console.c.
Some devices have not been able to output to the console
fast enough using shell_fprintf and end up timing out
unrelated functionality.
