config S3C2410_BOOT_WATCHDOG | ||
bool "S3C2410 Initialisation watchdog" | ||
depends on PLAT_S3C && 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 PLAT_S3C | ||
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 PLAT_S3C && 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 PLAT_S3C && 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 PLAT_S3C && 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. | ||
|
||

config S3C2410_LOWLEVEL_UART_PORT | ||

depends on PLAT_S3C | ||
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. |
