However, this does not seem to work for example for SSI1+SDMA, because the

Kexec needs omap4_cpu_kill, otherwise kexec will produce on SMP:

We need to reset CPU1 properly for kexec when booting different
kernel versions. Otherwise CPU1 will attempt to boot the the
previous kernel's start_secondary(). Note that the restctrl
register is different from the low-power mode wakeup register
CPU1_WAKEUP_NS_PA_ADDR. We need to configure both.

Let's fix the issue by defining SoC specific data to initialize
things in a more generic way. And let's also standardize omap-smp.c
to use soc_is instead of cpu_is while at it.

Kexec booted kernels on omap4 will hang early during the boot if the
booted kernel is different version from the previous kernel.

This is because the previous kernel may have configured low-power mode
using CPU1_WAKEUP_NS_PA_ADDR. In that case it points to the previous
kernel's omap4_secondary_startup(), and CPU1 can be in low power mode
from the previous kernel. When the new kernel configures the CPU1
clockdomain, CPU1 can wake from low power state prematurely during
omap44xx_clockdomains_init() running random code.

Let's fix the issue by configuring CPU1_WAKEUP_NS_PA_ADDR before we
call omap44xx_clockdomains_init(). Note that this is very early during
the init, and we will do proper CPU1 reset during SMP init a bit later
on in omap4_smp_prepare_cpus(). And we need to do this when SMP is
not enabled as the previous kernel may have had it enabled.

Prepare things for making kexec work on SMP omap variants by initializing
SARM RAM base early. This allows us to configure CPU1 for kexec in case
the previous kernel has put CPU1 in low power mode.

Note that this should not prevent moving other SAR RAM code to live
under drivers. However for kexec, we will need this very early.
