28 config S3C_LOWLEVEL_UART_PORT
29 int "S3C UART to use for low-level messages"
30 depends on ARCH_S3C64XX
33 Choice of which UART port to use for the low-level messages,
34 such as the `Uncompressing...` at start time. The value of
35 this configuration should be between zero and two. The port
36 must have been initialised by the boot-loader before use.
42 This option enables ATAGS based boot support code for
43 Samsung platforms, including static platform devices, legacy
44 clock, timer and interrupt initialization, etc.
46 Platforms that support only DT based boot need not to select
52 int "Space between gpio banks"
55 Add a number of spare GPIO entries between each bank for debugging
56 purposes. This allows any problems where an counter overflows from
57 one bank to another to be caught, at the expense of using a little
63 Internal configuration option to enable the s3c specific gpio

245 Say Y here if you want verbose debugging from the PM Suspend and
246 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
247 for more information.
249 config S3C_PM_DEBUG_LED_SMDK
250 bool "SMDK LED suspend/resume debugging"
251 depends on PM && (MACH_SMDK6410)
253 Say Y here to enable the use of the SMDK LEDs on the baseboard
254 for debugging of the state of the suspend and resume process.
256 Note, this currently only works for S3C64XX based SMDK boards.

259 bool "S3C2410 PM Suspend Memory CRC"
260 depends on PM && (PLAT_S3C24XX || ARCH_S3C64XX || ARCH_S5PV210)
263 Enable the PM code's memory area checksum over sleep. This option
264 will generate CRCs of all blocks of memory, and store them before
265 going to sleep. The blocks are then checked on resume for any
268 Note, this can take several seconds depending on memory size
271 See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
273 config SAMSUNG_PM_CHECK_CHUNKSIZE
274 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
275 depends on PM && SAMSUNG_PM_CHECK
278 Set the chunksize in Kilobytes of the CRC for checking memory
279 corruption over suspend and resume. A smaller value will mean that
280 the CRC data block will take more memory, but will identify any
281 faults with better precision.
283 See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
285 config SAMSUNG_WAKEMASK
