9 depends on ARCH_S3C2410
12 Base platform code for any Samsung S3C device
16 depends on ARCH_S3C2410 && (CPU_S3C2440 || CPU_S3C2442)
18 Support for S3C2440 and S3C2442 Samsung Mobile CPU based systems.
23 Common power management code for systems that are
24 compatible with the Simtec style of power management
26 config S3C2410_BOOT_WATCHDOG
27 bool "S3C2410 Initialisation watchdog"
28 depends on ARCH_S3C2410 && S3C2410_WATCHDOG
30 Say y to enable the watchdog during the kernel decompression
31 stage. If the kernel fails to uncompress, then the watchdog
32 will trigger a reset and the system should restart.
34 config S3C2410_BOOT_ERROR_RESET
35 bool "S3C2410 Reboot on decompression error"
36 depends on ARCH_S3C2410
38 Say y here to use the watchdog to reset the system if the
39 kernel decompressor detects an error during decompression.
41 config S3C2410_PM_DEBUG
42 bool "S3C2410 PM Suspend debug"
43 depends on ARCH_S3C2410 && PM
45 Say Y here if you want verbose debugging from the PM Suspend and
46 Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
49 config S3C2410_PM_CHECK
50 bool "S3C2410 PM Suspend Memory CRC"
51 depends on ARCH_S3C2410 && PM && CRC32
53 Enable the PM code's memory area checksum over sleep. This option
54 will generate CRCs of all blocks of memory, and store them before
55 going to sleep. The blocks are then checked on resume for any
58 config S3C2410_PM_CHECK_CHUNKSIZE
59 int "S3C2410 PM Suspend CRC Chunksize (KiB)"
60 depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK
63 Set the chunksize in Kilobytes of the CRC for checking memory
64 corruption over suspend and resume. A smaller value will mean that
65 the CRC data block will take more memory, but wil identify any
66 faults with better precision.
68 config S3C2410_LOWLEVEL_UART_PORT
69 int "S3C2410 UART to use for low-level messages"
72 Choice of which UART port to use for the low-level messages,
73 such as the `Uncompressing...` at start time. The value of
74 this configuration should be between zero and two. The port
75 must have been initialised by the boot-loader before use.
78 bool "S3C2410 DMA support"
79 depends on ARCH_S3C2410
81 S3C2410 DMA support. This is needed for drivers like sound which
82 use the S3C2410's DMA system to move data to and from the
85 config S3C2410_DMA_DEBUG
86 bool "S3C2410 DMA support debug"
87 depends on ARCH_S3C2410 && S3C2410_DMA
89 Enable debugging output for the DMA code. This option sends info
90 to the kernel log, at priority KERN_DEBUG.
