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

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