190 bool "S3C2410 Initialisation watchdog"
191 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
193 Say y to enable the watchdog during the kernel decompression
194 stage. If the kernel fails to uncompress, then the watchdog
195 will trigger a reset and the system should restart.
197 Although this uses the same hardware unit as the kernel watchdog
198 driver, it is not a replacement for it. If you use this option,
199 you will have to use the watchdg driver to either stop the timeout
200 or restart it. If you do not, then your kernel will reboot after
203 The driver uses a fixed timeout value, so the exact time till the
204 system resets depends on the value of PCLK. The timeout on an
205 200MHz s3c2410 should be about 30 seconds.
207 config S3C2410_BOOT_ERROR_RESET
208 bool "S3C2410 Reboot on decompression error"
209 depends on ARCH_S3C2410
211 Say y here to use the watchdog to reset the system if the
212 kernel decompressor detects an error during decompression.

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