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