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.

SPL build.

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().

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.

help
|
|
On x86 platforms the TSC timer tick starts at the value 0 on reset.
|
|
This it makes no sense to read the timer on boot and use that as the
|
|
base, since we will miss some time taken to load U-Boot, etc. This
|
|
delay is controlled by the SoC and we cannot reduce it, but for
|
|
bootstage we want to record the time since reset as accurately as
|
|
possible.
|
|
|
|
The only exception is when U-Boot is used as a secondary bootloader,
|
|
where this option should be enabled.
