154 config S3C2410_BOOT_WATCHDOG
155 bool "S3C2410 Initialisation watchdog"
156 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
158 Say y to enable the watchdog during the kernel decompression
159 stage. If the kernel fails to uncompress, then the watchdog
160 will trigger a reset and the system should restart.
162 Although this uses the same hardware unit as the kernel watchdog
163 driver, it is not a replacement for it. If you use this option,
164 you will have to use the watchdg driver to either stop the timeout
165 or restart it. If you do not, then your kernel will reboot after
168 The driver uses a fixed timeout value, so the exact time till the
169 system resets depends on the value of PCLK. The timeout on an
170 200MHz s3c2410 should be about 30 seconds.
172 config S3C2410_BOOT_ERROR_RESET
173 bool "S3C2410 Reboot on decompression error"
174 depends on ARCH_S3C2410
176 Say y here to use the watchdog to reset the system if the
177 kernel decompressor detects an error during decompression.

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