If the kernel fails to uncompress, then the watchdog will trigger a reset and the system should restart. config S3C_BOOT_ERROR_RESET bool "S3C Reboot on decompression error" help Say y here to use the watchdog to reset the system if the kernel decompressor detects an error during decompression. config S3C_BOOT_UART_FORCE_FIFO bool "Force UART FIFO on during boot process" default y help Say Y here to force the UART FIFOs on during the kernel uncompressor comment "Power management" config S3C2410_PM_DEBUG bool "S3C2410 PM Suspend debug" depends on PM help Say Y here if you want verbose debugging from the PM Suspend and Resume code. See for more information. config S3C2410_PM_CHECK bool "S3C2410 PM Suspend Memory CRC" depends on 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 config S3C2410_PM_CHECK_CHUNKSIZE int "S3C2410 PM Suspend CRC Chunksize (KiB)" depends on 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 config S3C_LOWLEVEL_UART_PORT int "S3C 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. # options for gpiolib support config S3C_GPIO_SPACE int "Space between gpio banks" default 0 help Add a number of spare GPIO entries between each bank for debugging purposes. This allows any problems where an counter overflows from one bank to another to be caught, at the expense of using a little more memory. config S3C_GPIO_TRACK bool help Internal configuration option to enable the s3c specific gpio chip tracking if the platform requires it. config S3C_GPIO_PULL_UPDOWN bool help Internal configuration to enable the correct GPIO pull helper config S3C_GPIO_PULL_DOWN bool help Internal configuration to enable the correct GPIO pull helper config S3C_GPIO_PULL_UP bool help Internal configuration to enable the correct GPIO pull helper config S3C_GPIO_CFG_S3C24XX bool help Internal configuration to enable S3C24XX style GPIO configuration functions. config S3C_GPIO_CFG_S3C64XX bool help Internal configuration to enable S3C64XX style GPIO configuration functions. # device definitions to compile in config S3C_DEV_HSMMC bool help Compile in platform device definitions for HSMMC code config S3C_DEV_HSMMC1 bool help Compile in platform device definitions for HSMMC channel 1 config S3C_DEV_I2C1 bool help Compile in platform device definitions for I2C channel 1 config S3C_DEV_FB bool help Compile in platform device definition for framebuffer config S3C_DEV_USB_HOST bool help Compile in platform device definition for USB host. endif
