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 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. # clock options config SAMSUNG_CLKSRC bool help Select the clock code for the clksrc implementation used by newer systems such as the S3C64XX. # options for IRQ support config SAMSUNG_IRQ_VIC_TIMER bool help Internal configuration to build the VIC timer interrupt code. config SAMSUNG_IRQ_UART bool help Internal configuration to build the IRQ UART demux code. # options for gpio configuration support config SAMSUNG_GPIOLIB_4BIT bool help GPIOlib file contains the 4 bit modification functions for gpio configuration. GPIOlib shall be compiled only for S3C64XX and S5P series of processors. 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. 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 S5P_GPIO_DRVSTR bool help Internal configuration to get and set correct GPIO driver strength helper config SAMSUNG_GPIO_EXTRA int "Number of additional GPIO pins" default 0 help Use additional GPIO space in addition to the GPIO's the SOC provides. This allows expanding the GPIO space for use with GPIO expanders. 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. # ADC driver config S3C_ADC bool "ADC common driver support" help Core support for the ADC block found in the Samsung SoC systems for drivers such as the touchscreen and hwmon to use to share this resource. # 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_HSMMC2 bool help Compile in platform device definitions for HSMMC channel 2 config S3C_DEV_HWMON bool help Compile in platform device definitions for HWMON 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. config S3C_DEV_USB_HSOTG bool help Compile in platform device definition for USB high-speed OtG config S3C_DEV_NAND bool help Compile in platform device definition for NAND controller config S3C_DEV_RTC bool help Complie in platform device definition for RTC config SAMSUNG_DEV_ADC bool help Compile in platform device definition for ADC controller config S3C64XX_DEV_SPI bool help Compile in platform device definitions for S3C64XX's type SPI controllers. config S3C64XX_DEV_TS bool help Common in platform device definitions for S3C64XX touchscreen device # DMA config S3C_DMA bool help Internal configuration for S3C DMA core config S3C_PL330_DMA bool select PL330 help S3C DMA API Driver for PL330 DMAC. comment "Power management" config SAMSUNG_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 S3C_PM_DEBUG_LED_SMDK bool "SMDK LED suspend/resume debugging" depends on PM && (MACH_SMDK6410) help Say Y here to enable the use of the SMDK LEDs on the baseboard for debugging of the state of the suspend and resume process. Note, this currently only works for S3C64XX based SMDK boards. config SAMSUNG_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 SAMSUNG_PM_CHECK_CHUNKSIZE int "S3C2410 PM Suspend CRC Chunksize (KiB)" depends on PM && SAMSUNG_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 endif
