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 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"

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"

# so only the early timer is available

default y if X86 && BOOTSTAGE
|
|
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().

|
|
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.

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.
