205 bool "S3C2410 Initialisation watchdog"
206 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
208 Say y to enable the watchdog during the kernel decompression
209 stage. If the kernel fails to uncompress, then the watchdog
210 will trigger a reset and the system should restart.
212 Although this uses the same hardware unit as the kernel watchdog
213 driver, it is not a replacement for it. If you use this option,
214 you will have to use the watchdg driver to either stop the timeout
215 or restart it. If you do not, then your kernel will reboot after
218 The driver uses a fixed timeout value, so the exact time till the
219 system resets depends on the value of PCLK. The timeout on an
220 200MHz s3c2410 should be about 30 seconds.
222 config S3C2410_BOOT_ERROR_RESET
223 bool "S3C2410 Reboot on decompression error"
224 depends on ARCH_S3C2410
226 Say y here to use the watchdog to reset the system if the
227 kernel decompressor detects an error during decompression.

233 bool "S3C2410 DMA support"
234 depends on ARCH_S3C2410
236 S3C2410 DMA support. This is needed for drivers like sound which
237 use the S3C2410's DMA system to move data to and from the
240 config S3C2410_DMA_DEBUG
241 bool "S3C2410 DMA support debug"
242 depends on ARCH_S3C2410 && S3C2410_DMA
244 Enable debugging output for the DMA code. This option sends info
245 to the kernel log, at priority KERN_DEBUG.
247 Note, it is easy to create and fill the log buffer in a small
248 amount of time, as well as using an significant percentage of
249 the CPU time doing so.
252 config S3C2410_PM_DEBUG
253 bool "S3C2410 PM Suspend debug"
254 depends on ARCH_S3C2410 && PM
256 Say Y here if you want verbose debugging from the PM Suspend and
257 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
258 for more information.
260 config S3C2410_PM_CHECK
261 bool "S3C2410 PM Suspend Memory CRC"
262 depends on ARCH_S3C2410 && PM && CRC32
264 Enable the PM code's memory area checksum over sleep. This option
265 will generate CRCs of all blocks of memory, and store them before
266 going to sleep. The blocks are then checked on resume for any
269 config S3C2410_PM_CHECK_CHUNKSIZE
270 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
271 depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK
274 Set the chunksize in Kilobytes of the CRC for checking memory
275 corruption over suspend and resume. A smaller value will mean that
276 the CRC data block will take more memory, but wil identify any
277 faults with better precision.
281 depends on PM && (ARCH_BAST || MACH_VR1000)
284 config S3C2410_LOWLEVEL_UART_PORT
285 int "S3C2410 UART to use for low-level messages"
288 Choice of which UART port to use for the low-level messages,
289 such as the `Uncompressing...` at start time. The value of
290 this configuration should be between zero and two. The port
291 must have been initialised by the boot-loader before use.
293 Note, this does not affect the port used by the debug messages,
294 which is a separate configuration.
