- menu "Timer Support"
- config TIMER
- bool "Enable driver model for timer drivers"
- depends on DM
- help
- Enable driver model for timer access. It uses the same API as
- lib/time.c, but now implemented by the uclass. The first timer
- will be used. The timer is usually a 32 bits free-running up
- counter. There may be no real tick, and no timer interrupt.
- config SPL_TIMER
- bool "Enable driver model for timer drivers in SPL"
- depends on TIMER && SPL
- help
- Enable support for timer drivers in SPL. These can be used to get
- a timer value when in SPL, or perhaps for implementing a delay
- function. This enables the drivers in drivers/timer as part of an
- SPL build.
- config TPL_TIMER
- bool "Enable driver model for timer drivers in TPL"
- depends on TIMER && TPL
- help
- Enable support for timer drivers in TPL. These can be used to get
- a timer value when in TPL, or perhaps for implementing a delay
- function. This enables the drivers in drivers/timer as part of an
- TPL build.
- config TIMER_EARLY
- bool "Allow timer to be used early in U-Boot"
- depends on TIMER
- help
- In some cases the timer must be accessible before driver model is
- active. Examples include when using CONFIG_TRACE to trace U-Boot's
- execution before driver model is set up. Enable this option to
- use an early timer. These functions must be supported by your timer
- driver: timer_early_get_count() and timer_early_get_rate().
- config ALTERA_TIMER
- bool "Altera timer support"
- depends on TIMER
- help
- Select this to enable a timer for Altera devices. Please find
- details on the "Embedded Peripherals IP User Guide" of Altera.
- config ATMEL_PIT_TIMER
- bool "Atmel periodic interval timer support"
- depends on TIMER
- help
- Select this to enable a periodic interval timer for Atmel devices,
- it is designed to offer maximum accuracy and efficient management,
- even for systems with long response time.
- config CADENCE_TTC_TIMER
- bool "Cadence TTC (Triple Timer Counter)"
- depends on TIMER
- help
- Enables support for the cadence ttc driver. This driver is present
- on Xilinx Zynq and ZynqMP SoCs.
- config SANDBOX_TIMER
- bool "Sandbox timer support"
- depends on SANDBOX && TIMER
- help
- Select this to enable an emulated timer for sandbox. It gets
- time from host os.
- config X86_TSC_TIMER
- bool "x86 Time-Stamp Counter (TSC) timer support"
- depends on TIMER && X86
- help
- Select this to enable Time-Stamp Counter (TSC) timer for x86.
- config OMAP_TIMER
- bool "Omap timer support"
- depends on TIMER
- help
- Select this to enable an timer for Omap devices.
- config AST_TIMER
- bool "Aspeed ast2400/ast2500 timer support"
- depends on TIMER
- default y if ARCH_ASPEED
- help
- Select this to enable timer for Aspeed ast2400/ast2500 devices.
- This is a simple sys timer driver, it is compatible with lib/time.c,
- but does not support any interrupts. Even though SoC has 8 hardware
- counters, they are all treated as a single device by this driver.
- This is mostly because they all share several registers which
- makes it difficult to completely separate them.
- config STI_TIMER
- bool "STi timer support"
- depends on TIMER
- default y if ARCH_STI
- help
- Select this to enable a timer for STi devices.
- config ARC_TIMER
- bool "ARC timer support"
- depends on TIMER && ARC && CLK
- help
- Select this to enable built-in ARC timers.
- ARC cores may have up to 2 built-in timers: timer0 and timer1,
- usually at least one of them exists. Either of them is supported
- in U-Boot.
- config AG101P_TIMER
- bool "AG101P timer support"
- depends on TIMER && NDS32
- help
- Select this to enable a timer for AG01P devices.
- config ATCPIT100_TIMER
- bool "ATCPIT100 timer support"
- depends on TIMER
- help
- Select this to enable a ATCPIT100 timer which will be embeded
- in AE3XX, AE250 boards.
- config ROCKCHIP_TIMER
- bool "Rockchip timer support"
- depends on TIMER
- help
- Select this to enable support for the timer found on
- Rockchip devices.
- config STM32_TIMER
- bool "STM32 timer support"
- depends on TIMER
- help
- Select this to enable support for the timer found on
- STM32 devices.
