+ 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
+ default y if X86
+ help
+ Select this to enable Time-Stamp Counter (TSC) timer for x86.

+config OMAP_TIMER
+ bool "Omap timer support"

+ 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.
