Bin Meng435ae762015-11-13 00:11:14 -08007 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
Thomas Chouc8a7ba92015-10-09 13:46:34 +08009 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.

13 bool "Enable driver model for timer drivers in SPL"
14 depends on TIMER && SPL
15 help
16 Enable support for timer drivers in SPL. These can be used to get
17 a timer value when in SPL, or perhaps for implementing a delay
18 function. This enables the drivers in drivers/timer as part of an
19 SPL build.

25 Enable support for timer drivers in TPL. These can be used to get
26 a timer value when in TPL, or perhaps for implementing a delay
27 function. This enables the drivers in drivers/timer as part of an

31 bool "Allow timer to be used early in U-Boot"
32 depends on TIMER
33 help
34 In some cases the timer must be accessible before driver model is
35 active. Examples include when using CONFIG_TRACE to trace U-Boot's
36 execution before driver model is set up. Enable this option to
37 use an early timer. These functions must be supported by your timer
38 driver: timer_early_get_count() and timer_early_get_rate().

69 default y if ARCH_ASPEED
70 help
71 Select this to enable timer for Aspeed ast2400/ast2500 devices.
72 This is a simple sys timer driver, it is compatible with lib/time.c,
73 but does not support any interrupts. Even though SoC has 8 hardware
74 counters, they are all treated as a single device by this driver.
75 This is mostly because they all share several registers which
76 makes it difficult to completely separate them.
