65 Say Y here if you are using the Nex Vision OTOM board
67 config MACH_NEXCODER_2440
68 bool "NexVision NEXCODER 2440 Light Board"
71 Say Y here if you are using the Nex Vision NEXCODER 2440 Light Board
77 depends on ARCH_S3C2410
79 Support for S3C2410 and S3C2410A family from the S3C24XX line
80 of Samsung Mobile CPUs.
84 depends on ARCH_S3C2410
86 Support for S3C2440 Samsung Mobile CPU based systems.

90 config S3C2410_BOOT_WATCHDOG
91 bool "S3C2410 Initialisation watchdog"
92 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
94 Say y to enable the watchdog during the kernel decompression
95 stage. If the kernel fails to uncompress, then the watchdog
96 will trigger a reset and the system should restart.
98 Although this uses the same hardware unit as the kernel watchdog
99 driver, it is not a replacement for it. If you use this option,
100 you will have to use the watchdg driver to either stop the timeout
101 or restart it. If you do not, then your kernel will reboot after
104 The driver uses a fixed timeout value, so the exact time till the
105 system resets depends on the value of PCLK. The timeout on an
106 200MHz s3c2410 should be about 30 seconds.

111 bool "S3C2410 DMA support"
112 depends on ARCH_S3C2410
114 S3C2410 DMA support. This is needed for drivers like sound which
115 use the S3C2410's DMA system to move data to and from the
118 config S3C2410_DMA_DEBUG
119 bool "S3C2410 DMA support debug"
120 depends on ARCH_S3C2410 && S3C2410_DMA
122 Enable debugging output for the DMA code. This option sends info
123 to the kernel log, at priority KERN_DEBUG.
125 Note, it is easy to create and fill the log buffer in a small
126 amount of time, as well as using an significant percentage of
127 the CPU time doing so.
130 config S3C2410_PM_DEBUG
131 bool "S3C2410 PM Suspend debug"
132 depends on ARCH_S3C2410 && PM
134 Say Y here if you want verbose debugging from the PM Suspend and
135 Resume code. See `Documentation/arm/Samsing-S3C24XX/Suspend.txt`
136 for more information.
138 config S3C2410_PM_CHECK
139 bool "S3C2410 PM Suspend Memory CRC"
140 depends on ARCH_S3C2410 && PM && CRC32
142 Enable the PM code's memory area checksum over sleep. This option
143 will generate CRCs of all blocks of memory, and store them before
144 going to sleep. The blocks are then checked on resume for any
147 config S3C2410_PM_CHECK_CHUNKSIZE
148 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
149 depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK
152 Set the chunksize in Kilobytes of the CRC for checking memory
153 corruption over suspend and resume. A smaller value will mean that
154 the CRC data block will take more memory, but wil identify any
155 faults with better precision.
159 depends on PM && (ARCH_BAST || MACH_VR1000)
162 config S3C2410_LOWLEVEL_UART_PORT
163 int "S3C2410 UART to use for low-level messages"
166 Choice of which UART port to use for the low-level messages,
167 such as the `Uncompressing...` at start time. The value of
168 this configuration should be between zero and two. The port
169 must have been initialised by the boot-loader before use.
171 Note, this does not affect the port used by the debug messages,
172 which is a separate configuration.
