OMAP timer driver directly typecasts fdt_addr_t to a pointer. This is
not strictly correct, as it gives a build warning when fdt_addr_t is u64.
So, use map_physmem for a proper typecasts.This is inspired by commit 167efe01bc5a9 ("dm: ns16550: Use an address
instead of a pointer for the uart base")Signed-off-by: Lokesh Vutla

Add support for the early timer so we can use tracing with sandbox again.
Signed-off-by: Simon Glass

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().Signed-off-by: Simon Glass

A few of the functions in the timer uclass are not marked with 'notrace'. Fix
this so that tracing can be used with CONFIG_TRACE.Signed-off-by: Simon Glass

A default invocation of sandbox U-Boot apparently uses no device tree,
which means that no timer is registers, which in turn means that the
sleep shell command hangs.Fix the sandbox timer code to register a device when there's no DT, just
like e.g. the sandbox reset driver does. When there's no DT, the DM uclass
can't initialize clock_rate from DT, so set a default value in the
timer code instead.Signed-off-by: Stephen Warren

If a timer has a zero clock_rate, get_tbclk() will return zero for it,
which will cause tick_to_time() to perform a division-by-zero, which will
crash U-Boot.Signed-off-by: Stephen Warren

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.Signed-off-by: Mugunthan V N

Right now i8254_init() is called from timer_init() in the tsc timer
driver. But actually i8254 and tsc are completely different things.
Since tsc timer has been converted to driver model, we should find
a new place that is appropriate for U-Boot to call i8254_init(),
which is now x86_cpu_init_f().Signed-off-by: Bin Meng

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.Signed-off-by: Bin Meng
