   3 config TIMER
   4         bool "Enable driver model for timer drivers"
   5         depends on DM
   6         help
   7           Enable driver model for timer access. It uses the same API as
   8           lib/time.c, but now implemented by the uclass. The first timer
   9           will be used. The timer is usually a 32 bits free-running up
  10           counter. There may be no real tick, and no timer interrupt.

  12 config TIMER_EARLY
  13         bool "Allow timer to be used early in U-Boot"
  14         depends on TIMER
  15         help
  16           In some cases the timer must be accessible before driver model is
  17           active. Examples include when using CONFIG_TRACE to trace U-Boot's
  18           execution before driver model is set up. Enable this option to
  19           use an early timer. These functions must be supported by your timer
  20           driver: timer_early_get_count() and timer_early_get_rate().
  21
  22 config ALTERA_TIMER
  23         bool "Altera timer support"
  24         depends on TIMER
  25         help
  26           Select this to enable a timer for Altera devices. Please find
  27           details on the "Embedded Peripherals IP User Guide" of Altera.

  29 config SANDBOX_TIMER
  30         bool "Sandbox timer support"
  31         depends on SANDBOX && TIMER
  32         help
  33           Select this to enable an emulated timer for sandbox. It gets
  34           time from host os.
  35
  36 config X86_TSC_TIMER
  37         bool "x86 Time-Stamp Counter (TSC) timer support"
  38         depends on TIMER && X86
  39         help
  40           Select this to enable Time-Stamp Counter (TSC) timer for x86.
  41
  42 config OMAP_TIMER
  43         bool "Omap timer support"
  44         depends on TIMER
  45         help
  46           Select this to enable an timer for Omap devices.
  47
  48 config AST_TIMER
  49         bool "Aspeed ast2400/ast2500 timer support"
  50         depends on TIMER
  51         default y if ARCH_ASPEED
  52         help
  53           Select this to enable timer for Aspeed ast2400/ast2500 devices.
  54           This is a simple sys timer driver, it is compatible with lib/time.c,
  55           but does not support any interrupts. Even though SoC has 8 hardware
  56           counters, they are all treated as a single device by this driver.
  57           This is mostly because they all share several registers which
  58           makes it difficult to completely separate them.
  59
  60 config STI_TIMER
  61         bool "STi timer support"
  62         depends on TIMER
  63         default y if ARCH_STI
  64         help
  65           Select this to enable a timer for STi devices.
  66
  67 config ARC_TIMER
  68         bool "ARC timer support"
  69         depends on TIMER && ARC && CLK
  70         help
  71           Select this to enable built-in ARC timers.
  72           ARC cores may have up to 2 built-in timers: timer0 and timer1,
  73           usually at least one of them exists. Either of them is supported
  74           in U-Boot.

  76 config AG101P_TIMER
  77         bool "AG101P timer support"
  78         depends on TIMER && NDS32
  79         help
  80           Select this to enable a timer for AG01P devices.
  81
  82 config AE3XX_TIMER
  83         bool "AE3XX timer support"
  84         depends on TIMER && NDS32
  85         help
  86           Select this to enable a timer for AE3XX devices.
