224 bool "S3C2410 Initialisation watchdog"
225 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
227 Say y to enable the watchdog during the kernel decompression
228 stage. If the kernel fails to uncompress, then the watchdog
229 will trigger a reset and the system should restart.
231 Although this uses the same hardware unit as the kernel watchdog
232 driver, it is not a replacement for it. If you use this option,
233 you will have to use the watchdg driver to either stop the timeout
234 or restart it. If you do not, then your kernel will reboot after
237 The driver uses a fixed timeout value, so the exact time till the
238 system resets depends on the value of PCLK. The timeout on an
239 200MHz s3c2410 should be about 30 seconds.
241 config S3C2410_BOOT_ERROR_RESET
242 bool "S3C2410 Reboot on decompression error"
243 depends on ARCH_S3C2410
245 Say y here to use the watchdog to reset the system if the
246 kernel decompressor detects an error during decompression.

252 bool "S3C2410 DMA support"
253 depends on ARCH_S3C2410
255 S3C2410 DMA support. This is needed for drivers like sound which
256 use the S3C2410's DMA system to move data to and from the
259 config S3C2410_DMA_DEBUG
260 bool "S3C2410 DMA support debug"
261 depends on ARCH_S3C2410 && S3C2410_DMA
263 Enable debugging output for the DMA code. This option sends info
264 to the kernel log, at priority KERN_DEBUG.
266 Note, it is easy to create and fill the log buffer in a small
267 amount of time, as well as using an significant percentage of
268 the CPU time doing so.
271 config S3C2410_PM_DEBUG
272 bool "S3C2410 PM Suspend debug"
273 depends on ARCH_S3C2410 && PM
275 Say Y here if you want verbose debugging from the PM Suspend and
276 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
277 for more information.
279 config S3C2410_PM_CHECK
280 bool "S3C2410 PM Suspend Memory CRC"
281 depends on ARCH_S3C2410 && PM && CRC32
283 Enable the PM code's memory area checksum over sleep. This option
284 will generate CRCs of all blocks of memory, and store them before
285 going to sleep. The blocks are then checked on resume for any

289 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
290 depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK
293 Set the chunksize in Kilobytes of the CRC for checking memory
294 corruption over suspend and resume. A smaller value will mean that
295 the CRC data block will take more memory, but wil identify any
296 faults with better precision.

303 config S3C2410_LOWLEVEL_UART_PORT
304 int "S3C2410 UART to use for low-level messages"
307 Choice of which UART port to use for the low-level messages,
308 such as the `Uncompressing...` at start time. The value of
309 this configuration should be between zero and two. The port
310 must have been initialised by the boot-loader before use.
312 Note, this does not affect the port used by the debug messages,
313 which is a separate configuration.
