The value used for boot_params in h7201-eval.c is nonsensical, given that
PLAT_PHYS_OFFSET is defined to 0x40000000.  Left unchanged to purposely
break the build to get its maintainer's attention.

The boot_params member of the mdesc structure is used to provide a
default physical address for the ATAG list.  Since this value is fixed
at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET,
it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT
usage.

Let's introduce atag_offset which should contains only the relative
offset from PHYS_OFFSET instead of an absolute value, in preparation
to move all instance of boot_params over to it.

Instead of setting up a match interrupt for 'current_time + delta'
on ->set_next_event(), program timer 0 to count down from 'delta - 1'
and trigger an interrupt when it reaches zero.

Currently, arch-mmp/time.c uses timer 0 both as a clocksource timer
and as a clockevent timer, the latter by setting up a comparator
interrupt to match on 'current_time + delta'.  This is problematic
if delta is small enough, as that can lead to 'current_time + delta'
already being in the past when comparator setup has finished, leading
to the requested event not triggering.

As there is also a silicon issue that requires stopping a timer's
counter while writing to one of its match registers, we'll switch to
using two separate timers -- timer 0 as clockevent timer, which we'll
start and stop on every invocation of ->set_next_event(), and timer 1
as clocksource timer, which will be free-running.

This first patch enables timer 1 on boot, so that we can use it as
clocksource timer.

	    ARM: pxa: add iwmmx support for PJ4

which does:

-       mrc     p15, 0, r2, c15, c1, 0
-       orr     r2, r2, #0x3                    @ enable access to CP0 and CP1
-       mcr     p15, 0, r2, c15, c1, 0
+       @ enable access to CP0 and CP1
+       XSC(mrc p15, 0, r2, c15, c1, 0)
+       XSC(orr r2, r2, #0x3)
+       XSC(mcr p15, 0, r2, c15, c1, 0)

but then later does:

-       mrc     p15, 0, r4, c15, c1, 0
-       orr     r4, r4, #0x3                    @ enable access to CP0 and CP1

The PCI nanoengine driver in the SA1100 machine probably has not
been building for some time. It probably dragged hardware.h
in implicitly and now it doesn't anymore. After this an SA1100
build selecting all system variants will build successfully.

If CONFIG_OMAP_32K_TIMER is not selected and dmtimer is used as clocksource, the
timer stops counting once overflow occurs as it was not set in autoreload mode.
This results into timekeeping failure: for example, 'sleep 1' at the shell after
the timer counter overflow would hang.

This patch sets up autoreload when starting the clocksource timer which fixes
the above issue.
