depends on ARCH_S3C64XX
default 0
help
Choice of which UART port to use for the low-level messages,
such as the `Uncompressing...` at start time. The value of
this configuration should be between zero and two. The port
must have been initialised by the boot-loader before use.
config SAMSUNG_ATAGS

help
This option enables ATAGS based boot support code for
Samsung platforms, including static platform devices, legacy
clock, timer and interrupt initialization, etc.
Platforms that support only DT based boot need not to select
this option.

help
Add a number of spare GPIO entries between each bank for debugging
purposes. This allows any problems where an counter overflows from
one bank to another to be caught, at the expense of using a little
more memory.

chip tracking if the platform requires it.

Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
for more information.
config S3C_PM_DEBUG_LED_SMDK
bool "SMDK LED suspend/resume debugging"
depends on PM && (MACH_SMDK6410)
help
Say Y here to enable the use of the SMDK LEDs on the baseboard
for debugging of the state of the suspend and resume process.
Note, this currently only works for S3C64XX based SMDK boards.
config SAMSUNG_PM_CHECK
bool "S3C2410 PM Suspend Memory CRC"
depends on PM
select CRC32
help
Enable the PM code's memory area checksum over sleep. This option
will generate CRCs of all blocks of memory, and store them before
going to sleep. The blocks are then checked on resume for any
errors.
Note, this can take several seconds depending on memory size
and CPU speed.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
config SAMSUNG_PM_CHECK_CHUNKSIZE
int "S3C2410 PM Suspend CRC Chunksize (KiB)"
depends on PM && SAMSUNG_PM_CHECK
default 64
help
Set the chunksize in Kilobytes of the CRC for checking memory
corruption over suspend and resume. A smaller value will mean that
the CRC data block will take more memory, but will identify any
faults with better precision.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
config SAMSUNG_WAKEMASK
