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 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 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 AE3XX_TIMER
bool "AE3XX timer support"
depends on TIMER && NDS32
help
Select this to enable a timer for AE3XX devices.
