The interruption support had be removed for ARM architecture and
the function get_timer_masked() is no more used except in some
the timer.c files.

This patch clean each timer.c which implement this function and
remove the associated prototype in u-boot-arm.h

For timer.c, I don't verify if the weak version of get_timer
(in lib/time.c) can be used

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.

This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories.  All refernces to the former locations are updated to
the current locations.  For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.

The gd will be cleared at first so we don't need to set arch.tbl to 0.
In addition, the checks later against lastinc also work fine with an
initial value of 0 here.  This also brings us in line with sunxi code
for example.

- In arch/arm/cpu/armv7/omap-common/timer.c,
  drivers/mtd/nand/omap_gpmc.c and drivers/net/cpsw.c add #include files
  that the driver needs but had been relying on <config.h> to bring in.
- In arch/arm/cpu/armv7/omap-common/lowlevel_init.S add <config.h>
- In am335x_evm.h and pcm051.h don't globally include
  <asm/arch/hardware.h> and <asm/arch/cpu.h> but just <asm/arch/omap.h>
  as that is the only include which defines things the config uses.

In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into
timer_init()

As implemented now the timer used to implement __udelay counts
to 0xffffffff and then gets stuck there because the the programmed
reload value is 0xffffffff.  This value is not only wrong but
illegal according to the reference manual.

One can reproduce the bug by leaving a board at the u-boot prompt
for sometime then issuing a sleep command.  The sleep will hang
forever.

The timer is a count up timer that reloads as it rolls over
from 0xffffffff so the correct load value is 0.

Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce
a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss

The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.

The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9

Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.

The two architectures are similar enough that substantial code can be shared.

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow

so now rename it as int timer_init(void) and use interrupt_init for interrupt

btw also remane the corresponding file to the functionnality implemented

as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c
