lib: time: Add microsecond timer

2019-10-31T11:22:53+00:00

Add get_timer_us(), which is useful e.g. when we need higher
precision timestamps.

lib: time: export usec_to_tick()

2019-06-04T20:09:26+00:00

In the UEFI Stall() boottime service we need access to usec_to_tick().

Export the function.

Remove redundant implementation in arch/arm/mach-rockchip/rk_timer.c.

lib: time: update module enable MACRO

2019-03-29T14:53:18+00:00

We'd better use correct way to check if module has enabled.
for we have 3 timer MACRO:
- CONFIG_TIMER
- CONFIG_SPL_TIMER
- CONFIG_TPL_TIMER

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

bootstage: Provide a default timer function

If CONFIG_SYS_TIMER_COUNTER is used we can provide a default microsecond
timer implementation.

delay: collect {m, n, u}delay declarations to include/linux/delay.h

2017-01-14T21:46:28+00:00

Currently, mdelay() and udelay() are declared in include/common.h,
while ndelay() in include/linux/compat.h.  It would be nice to
collect them into include/linux/delay.h like Linux.

While we are here, fix the ndelay() implementation; I used the
DIV_ROUND_UP() instead of (x)/1000 because it must wait *longer*
than the given period of time.

timer: Provide an early timer

2016-02-26T15:53:10+00:00

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().

dm: timer: uclass: add timer init in uclass driver to add timer device

2016-01-21T02:06:21+00:00

Adding timer init function in timer-uclass driver to create and
initialize the timer device on platforms where u-boot,dm-pre-reloc
is not used. Since there will be multiple timer devices in the
system, adding a tick-timer node in chosen node to know which
timer device to be used as tick timer in u-boot.

dm: timer: Support 64-bit counter

2015-12-01T13:23:51+00:00

There are timers with a 64-bit counter value but current timer
uclass driver assumes a 32-bit one. Modify timer_get_count()
to ask timer driver to always return a 64-bit counter value,
and provide an inline helper function timer_conv_64() to handle
the 32-bit/64-bit conversion automatically.
