43 config S3C_BOOT_WATCHDOG
44 bool "S3C Initialisation watchdog"
45 depends on S3C2410_WATCHDOG
47 Say y to enable the watchdog during the kernel decompression
48 stage. If the kernel fails to uncompress, then the watchdog
49 will trigger a reset and the system should restart.
51 config S3C_BOOT_ERROR_RESET
52 bool "S3C Reboot on decompression error"
54 Say y here to use the watchdog to reset the system if the
55 kernel decompressor detects an error during decompression.
57 config S3C_BOOT_UART_FORCE_FIFO
58 bool "Force UART FIFO on during boot process"
61 Say Y here to force the UART FIFOs on during the kernel

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

129 Internal configuration to enable the correct GPIO pull helper
131 config S3C_GPIO_PULL_DOWN
134 Internal configuration to enable the correct GPIO pull helper
