config S3C_BOOT_WATCHDOG
bool "S3C Initialisation watchdog"
depends on PLAT_S3C && S3C2410_WATCHDOG
help
Say y to enable the watchdog during the kernel decompression
stage. If the kernel fails to uncompress, then the watchdog
will trigger a reset and the system should restart.
config S3C_BOOT_ERROR_RESET
bool "S3C Reboot on decompression error"
depends on PLAT_S3C
help
Say y here to use the watchdog to reset the system if the
kernel decompressor detects an error during decompression.

Say Y here to force the UART FIFOs on during the kernel
uncompressor

config S3C2410_PM_DEBUG
bool "S3C2410 PM Suspend debug"
depends on PLAT_S3C && PM
help
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 S3C2410_PM_CHECK
bool "S3C2410 PM Suspend Memory CRC"
depends on PLAT_S3C && PM && 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 S3C2410_PM_CHECK_CHUNKSIZE
int "S3C2410 PM Suspend CRC Chunksize (KiB)"
depends on PLAT_S3C && PM && S3C2410_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 wil identify any
faults with better precision.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
config S3C_LOWLEVEL_UART_PORT
int "S3C UART to use for low-level messages"
depends on PLAT_S3C
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.
