Most peripherals on the i.MX51 have an Off-Platform Peripheral Access
Control Register (OPACR) in which the access rights (together with the
MPROT registers) can be declared.
However, this does not seem to work for example for SSI1+SDMA, because the
supervisor bit is not set for the SDMA unit.
A similar problem was described in the patch for i.MX53 CPU
(ARM: i.MX53: globally disable supervisor protect), and the same solution
is applicable for i.MX51 CPU.
Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

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.

  This time I am very grateful that Ricardo Ribalda Delgado went in and
  fixed my stupid refcounting mistakes in the removal path for GPIO

     gpio_chip pointer is NULL).

   - Fix unaligned reference counters: we were ending on +3 after all
     said and done.  It should be 0.  Remove an extraneous get_device(),
     and call cdev_del() followed by device_del() in gpiochip_remove()
     instead and the count goes to zero and calls the release() function
     properly.

   - Fix a compile warning due to a missing #include in the OF/device
     tree portions.

   - Select ANON_INODES for GPIOLIB, we're using that for our character
     device.  Some randconfig tests disclosed the problem.
