169 bool "S3C2410 Initialisation watchdog"
170 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
172 Say y to enable the watchdog during the kernel decompression
173 stage. If the kernel fails to uncompress, then the watchdog
174 will trigger a reset and the system should restart.
176 Although this uses the same hardware unit as the kernel watchdog
177 driver, it is not a replacement for it. If you use this option,
178 you will have to use the watchdg driver to either stop the timeout
179 or restart it. If you do not, then your kernel will reboot after
182 The driver uses a fixed timeout value, so the exact time till the
183 system resets depends on the value of PCLK. The timeout on an
184 200MHz s3c2410 should be about 30 seconds.
186 config S3C2410_BOOT_ERROR_RESET
187 bool "S3C2410 Reboot on decompression error"
188 depends on ARCH_S3C2410
190 Say y here to use the watchdog to reset the system if the
191 kernel decompressor detects an error during decompression.

197 bool "S3C2410 DMA support"
198 depends on ARCH_S3C2410
200 S3C2410 DMA support. This is needed for drivers like sound which
201 use the S3C2410's DMA system to move data to and from the
204 config S3C2410_DMA_DEBUG
205 bool "S3C2410 DMA support debug"
206 depends on ARCH_S3C2410 && S3C2410_DMA
208 Enable debugging output for the DMA code. This option sends info
209 to the kernel log, at priority KERN_DEBUG.
211 Note, it is easy to create and fill the log buffer in a small
212 amount of time, as well as using an significant percentage of
213 the CPU time doing so.
216 config S3C2410_PM_DEBUG
217 bool "S3C2410 PM Suspend debug"
218 depends on ARCH_S3C2410 && PM
220 Say Y here if you want verbose debugging from the PM Suspend and
221 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
222 for more information.
224 config S3C2410_PM_CHECK
225 bool "S3C2410 PM Suspend Memory CRC"
226 depends on ARCH_S3C2410 && PM && CRC32
228 Enable the PM code's memory area checksum over sleep. This option
229 will generate CRCs of all blocks of memory, and store them before
230 going to sleep. The blocks are then checked on resume for any
233 config S3C2410_PM_CHECK_CHUNKSIZE
234 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
235 depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK
238 Set the chunksize in Kilobytes of the CRC for checking memory
239 corruption over suspend and resume. A smaller value will mean that
240 the CRC data block will take more memory, but wil identify any
241 faults with better precision.
245 depends on PM && (ARCH_BAST || MACH_VR1000)
248 config S3C2410_LOWLEVEL_UART_PORT
249 int "S3C2410 UART to use for low-level messages"
252 Choice of which UART port to use for the low-level messages,
253 such as the `Uncompressing...` at start time. The value of
254 this configuration should be between zero and two. The port
255 must have been initialised by the boot-loader before use.
257 Note, this does not affect the port used by the debug messages,
258 which is a separate configuration.
