If timer_init() is made a weak stub function, then it allows us to
remove several empty timer_init functions for those boards that
already have a timer initialized when u-boot starts. Architectures
that use the timer framework may also remove the need for timer.c.Signed-off-by: Darwin Rambo

Commit 8dfafdde88eb ("Introduce common timer functions") created a
common definition of usec_to_tick() which had a couple problems:static unsigned long long usec_to_tick(unsigned long usec)
{
uint64_t tick = usec * get_tbclk();That likely overflows.
usec *= get_tbclk();
That was an attempt to fix it by performing the multiply after the
promotion of usec to 64-bit, but was applied to the wrong variable,
which was never used.This patch fixes these issues. A user-visible symptom of the problem was
the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print:Waiting for Ethernet connection... unable to connect.
... with no delay before "unable to connect". There are likely other
symptoms.Signed-off-by: Stephen Warren

A weak annotation is needed in order to prevent link errors when
get_ticks is overridden. This fixes sandbox build.Signed-off-by: Rob Herring

Many platforms duplicate pretty much the same timer code yet they all have
a 32-bit freerunning counter register. Create a common implementation that
minimally requires 2 or 3 defines to add timer support:CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts downAll functions are weak or ifdef'ed so they can still be overriden by any
platform.Signed-off-by: Rob Herring

According to the README, CONFIG_SYS_HZ must be 1000 and most platforms
follow that. In preparation to remove CONFIG_SYS_HZ from all these
platforms, provide a common definition. The platforms which use a value
other than 1000 will get build warning now. These configs are:include/configs/M5271EVB.h:#define CONFIG_SYS_HZ 1000000
include/configs/balloon3.h:#define CONFIG_SYS_HZ 3250000 /* Timer @ 3250000 Hz */
include/configs/idmr.h:#define CONFIG_SYS_HZ (50000000 / 64)

include/configs/mx1ads.h:#define CONFIG_SYS_HZ 3686400

The standalone example does not have get_timer() defined, so we cannot
rely on it being available.Move the timer function into boootstage.c to avoid this problem.
This corrects a build breakage for the standalone example on some boards.

Define timer_get_boot_us() which returns the number of microseconds
since boot. If undefined then we use get_timer() * 1000.We can fit this in a 32-bit register which keeps everyone happy on
the efficiency side. It will wrap around after about an hour. If we
are still looking at it after an hour then we had better not be
timing the boot.Signed-off-by: Simon Glass
