config S3C2410_BOOT_WATCHDOG
bool "S3C2410 Initialisation watchdog"
depends on ARCH_S3C2410 && 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.
Although this uses the same hardware unit as the kernel watchdog
driver, it is not a replacement for it. If you use this option,
you will have to use the watchdg driver to either stop the timeout
or restart it. If you do not, then your kernel will reboot after
startup.
The driver uses a fixed timeout value, so the exact time till the
system resets depends on the value of PCLK. The timeout on an
200MHz s3c2410 should be about 30 seconds.

config S3C2410_DMA
bool "S3C2410 DMA support"
depends on ARCH_S3C2410
help
S3C2410 DMA support. This is needed for drivers like sound which
use the S3C2410's DMA system to move data to and from the
peripheral blocks.
config S3C2410_DMA_DEBUG
bool "S3C2410 DMA support debug"
depends on ARCH_S3C2410 && S3C2410_DMA
help
Enable debugging output for the DMA code. This option sends info
to the kernel log, at priority KERN_DEBUG.
Note, it is easy to create and fill the log buffer in a small
amount of time, as well as using an significant percentage of
the CPU time doing so.
config S3C2410_PM_DEBUG
bool "S3C2410 PM Suspend debug"

bool "S3C2410 PM Suspend Memory CRC"
depends on ARCH_S3C2410 && 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.

int "S3C2410 PM Suspend CRC Chunksize (KiB)"
depends on ARCH_S3C2410 && 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.
config S3C2410_LOWLEVEL_UART_PORT
int "S3C2410 UART to use for low-level messages"
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.
Note, this does not affect the port used by the debug messages,
which is a separate configuration.
