Remove the majority of cache flushing calls from the individual platform
files. This is now handled by the core code.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
The L1 data cache flush needs to be after highbank_set_cpu_jump call which
pollutes the cache with the l2x0_lock. This causes other cores to deadlock
waiting for the l2x0_lock. Moving the flush of the entire data cache after
highbank_set_cpu_jump fixes the problem. Use flush_cache_louis instead of
flush_cache_all are that is sufficient to flush only the L1 data cache.
flush_cache_louis did not exist when highbank_cpu_die was originally
written.
With PL310 errata 769419 enabled, a wmb is inserted into idle which takes
the l2x0_lock. This makes the problem much more easily hit and causes
reset to hang.

This converts arm and arm64 to use CLKSRC_OF DT based initialization for
the arch timer. A new function arch_timer_arch_init is added to allow for
arch specific setup.
This has a side effect of enabling sched_clock on omap5 and exynos5. There
should not be any reason not to use the arch timers for sched_clock.

The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.
Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big
