+         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

+         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

+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().

          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.

+       bool "x86 Time-Stamp Counter (TSC) timer support"
+       depends on TIMER && X86
+       help

+
+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

+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
