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.
60 config S3C_BOOT_UART_FORCE_FIFO
61 bool "Force UART FIFO on during boot process"
65 Say Y here to force the UART FIFOs on during the kernel

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