45 config S3C_BOOT_WATCHDOG
46 bool "S3C Initialisation watchdog"
47 depends on PLAT_S3C && S3C2410_WATCHDOG
49 Say y to enable the watchdog during the kernel decompression
50 stage. If the kernel fails to uncompress, then the watchdog
51 will trigger a reset and the system should restart.
53 config S3C_BOOT_ERROR_RESET
54 bool "S3C Reboot on decompression error"
57 Say y here to use the watchdog to reset the system if the
58 kernel decompressor detects an error during decompression.

62 config S3C2410_PM_DEBUG
63 bool "S3C2410 PM Suspend debug"
64 depends on PLAT_S3C && PM
66 Say Y here if you want verbose debugging from the PM Suspend and
67 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
70 config S3C2410_PM_CHECK
71 bool "S3C2410 PM Suspend Memory CRC"
72 depends on PLAT_S3C && PM && CRC32
74 Enable the PM code's memory area checksum over sleep. This option
75 will generate CRCs of all blocks of memory, and store them before
76 going to sleep. The blocks are then checked on resume for any
79 Note, this can take several seconds depending on memory size
82 See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
84 config S3C2410_PM_CHECK_CHUNKSIZE
85 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
86 depends on PLAT_S3C && PM && S3C2410_PM_CHECK
89 Set the chunksize in Kilobytes of the CRC for checking memory
90 corruption over suspend and resume. A smaller value will mean that
91 the CRC data block will take more memory, but wil identify any
92 faults with better precision.
94 See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
96 config S3C_LOWLEVEL_UART_PORT
97 int "S3C UART to use for low-level messages"
101 Choice of which UART port to use for the low-level messages,
102 such as the `Uncompressing...` at start time. The value of
103 this configuration should be between zero and two. The port
104 must have been initialised by the boot-loader before use.
106 # options for gpiolib support
108 config S3C_GPIO_SPACE
109 int "Space between gpio banks"
112 Add a number of spare GPIO entries between each bank for debugging
113 purposes. This allows any problems where an counter overflows from
114 one bank to another to be caught, at the expense of using a little
117 config S3C_GPIO_TRACK
120 Internal configuration option to enable the s3c specific gpio
121 chip tracking if the platform requires it.
