A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3

ARM: stop: execute platform callback from cpu_stop code
Sending IPI_CPU_STOP to a CPU causes it to execute a busy cpu_relax

system since the secondary CPUs do not reset.
This patch adds a callback to platform_cpu_kill, defined when
CONFIG_HOTPLUG_CPU=y, from the ipi_cpu_stop handling code. This function
currently just returns 1 on all platforms that define it but allows them
to do something more sophisticated in the future.

ARM: reset: implement soft_restart for jumping to a physical address
Tools such as kexec and CPU hotplug require a way to reset the processor
and branch to some code in physical space. This requires various bits of
jiggery pokery with the caches and MMU which, when it goes wrong, tends
to lock up the system.
This patch fleshes out the soft_restart implementation so that it
branches to the reset code using the identity mapping. This requires us
to change to a temporary stack, held within the kernel image as a static
array, to avoid conflicting with the new view of memory.
Will Deacon [Wed, 8 Jun 2011 14:29:00 +0000 (15:29 +0100)]
ARM: lib: add call_with_stack function for safely changing stack
When disabling the MMU, it is necessary to take out a 1:1 identity map
of the reset code so that it can safely be executed with and without
the MMU active. To avoid the situation where the physical address of the
reset code aliases with the virtual address of the active stack (which
cannot be included in the 1:1 mapping), it is desirable to change to a
new stack at a location which is less likely to alias.
This code adds a new lib function, call_with_stack:
which changes the stack to point at the sp parameter, before invoking
fn(arg) with the new stack selected.
