config PLAT_S3C24XX
bool
depends on ARCH_S3C2410
default y if ARCH_S3C2410
select NO_IOPORT
help
Base platform code for any Samsung S3C device
if PLAT_S3C24XX
config CPU_S3C244X
bool
depends on ARCH_S3C2410 && (CPU_S3C2440 || CPU_S3C2442)
help
Support for S3C2440 and S3C2442 Samsung Mobile CPU based systems.
config PM_SIMTEC
bool
help
Common power management code for systems that are
compatible with the Simtec style of power management
config S3C2410_BOOT_WATCHDOG
bool "S3C2410 Initialisation watchdog"
depends on ARCH_S3C2410 && S3C2410_WATCHDOG
help
Say y to enable the watchdog during the kernel decompression
stage. If the kernel fails to uncompress, then the watchdog
will trigger a reset and the system should restart.
config S3C2410_BOOT_ERROR_RESET
bool "S3C2410 Reboot on decompression error"
depends on ARCH_S3C2410
help
Say y here to use the watchdog to reset the system if the
kernel decompressor detects an error during decompression.
config S3C2410_PM_DEBUG
bool "S3C2410 PM Suspend debug"
depends on ARCH_S3C2410 && PM
help
Say Y here if you want verbose debugging from the PM Suspend and
Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
for more information.
config S3C2410_PM_CHECK
bool "S3C2410 PM Suspend Memory CRC"
depends on ARCH_S3C2410 && PM && CRC32
help
Enable the PM code's memory area checksum over sleep. This option
will generate CRCs of all blocks of memory, and store them before
going to sleep. The blocks are then checked on resume for any
errors.
Note, this can take several seconds depending on memory size
and CPU speed.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
config S3C2410_PM_CHECK_CHUNKSIZE
int "S3C2410 PM Suspend CRC Chunksize (KiB)"
depends on ARCH_S3C2410 && PM && S3C2410_PM_CHECK
default 64
help
Set the chunksize in Kilobytes of the CRC for checking memory
corruption over suspend and resume. A smaller value will mean that
the CRC data block will take more memory, but wil identify any
faults with better precision.
See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
config S3C2410_LOWLEVEL_UART_PORT
int "S3C2410 UART to use for low-level messages"
default 0
help
Choice of which UART port to use for the low-level messages,
such as the `Uncompressing...` at start time. The value of
this configuration should be between zero and two. The port
must have been initialised by the boot-loader before use.
config S3C2410_DMA
bool "S3C2410 DMA support"
depends on ARCH_S3C2410
help
S3C2410 DMA support. This is needed for drivers like sound which
use the S3C2410's DMA system to move data to and from the
peripheral blocks.
config S3C2410_DMA_DEBUG
bool "S3C2410 DMA support debug"
depends on ARCH_S3C2410 && S3C2410_DMA
help
Enable debugging output for the DMA code. This option sends info
to the kernel log, at priority KERN_DEBUG.
config MACH_SMDK
bool
help
Common machine code for SMDK2410 and SMDK2440
