ARM: mmu: Add VBAR setup ...

Add code to make sure that normal vector exception table, when it is
used due to unavailability of the high vector table, was not re-mapped
from 0x0 via VBAR by someone else before us.

reset: fix non GPIO reset ...

The reset controller structure is zero initialized in the OF
reset case, but as 0 is also a valid GPIO number the current
code tries to assert/deassert the GPIO instead of calling into
the reset controller device.

of_path: Fix bug with partitions, simply code ...

In commit 75b6827 using a path that
has a partition description broke.

Fix this and simpfy the code some.

There is no need to loop over each string in the path property:  it's
defined to have at most one parition description, no extant dts has
more than one, and how it would handle more than one didn't make sense
anyway.

Once not looping, __of_find_path() just needs the partition
description text, not both the original node and property name to look
it up from.

When using a partition description, don't lookup the cdev of the node
just to replace it with the partition's cdev.

bcm283x: mbox: align to cachesize ...

This patch change the align of mbox stack resource to 32. The reason is
that I had some experience with bcm2836 and the mbox implementation,
after setting the align to 64(on bcm2836) the issues was gone.

I found these values inside the u-boot implementation, they use 32
(bcm2835) and 64 (bcm2836).

bcm2835: introduce mach-bcm283x ...

This patch changes the most part of mach-bcm2835 to mach-bcm283x. This
prepares to add RPi2 support which is a bcm2836. This patch changes the
Kconfig entry namens to BCM283X for drivers only. These drivers should
working the same in bcm2836.

While updating defconfig I added LED support/trigger option.

environment: allow saving of symbolic link changes ...

Currently it is not possible to change symbolic links in the default
environment. For example if the default environment contains the
link "current_boot -> mmc" then the following does not work:

$ rm current_boot
$ ln net current_boot
$ saveenv

After reset the link is still pointing to "mmc" and this error appears:

"symlink: /env/boot/current_boot -> net : error -17"

The patch fixes the above problem and moves the "ENV_FLAG_NO_OVERWRITE"
to enable handling of symbolic links in this case too.

bootstrap: Boot barebox with kernel calling convention ...

In commit 8e3ddc1 the bootm code was
changed to boot barebox using the same calling convention as the
kernel.  Which on ARM is to pass three arguments which are zero, an
architecture code, and a params pointer.

A 2nd stage barebox can be booted using lib/bootstrap, which is
different code from bootm.  This code just leaves garbage in the first
three parameters and so doesn't follow the convention.

Change it to be compatible with the ARM kernel booting convention.
This just sends a zero for the architecture, since the code for
architectures depends on boot[zmu] and something using bootstrap
wouldn't have those too.  And it just passes NULL for the params since
we don't have a way to pass a device tree from the preloader.

All users of bootstrap are ARM based, but the code is in lib so a
non-ARM board might someday make use of it.  If the current code would
work for them, then the change here will be ok too.

MCI: init device_node for MCI mainarea cdev ...

This fixes a regression, where boards specifying the environment
path using the form device-path = &phandle, "partname:part" would
be unable to find their env.

This is due to of_find_path() switching to cdev_by_device_node()
internally, which expects the device_node member of the main
area cdev to be initialized.
