Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot.
This patch is adding minimal support to get U-Boot boot.
U-Boot on R5 runs out of DDR with default configuration that's why
DDR needs to be partitioned if there is something else running on arm64.
Console is done via Cadence uart driver and the first Cadence Triple
Timer Counter is used for time.

This configuration with uart1 was tested on zcu100-revC.

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

This converts the following to Kconfig:
   CONFIG_CONS_INDEX

We have existing entries for this option in a number of places, with
different guards on them.  They're also sometimes used for things not
directly inside of the serial driver.  First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it.  Next, consolidate all of these into the single entry in
drivers/serial/Kconfig.  Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

TI_SECURE_DEVICE is used by both OMAP2+ and Keystone2 family devices,
and so when ARCH_OMAP2PLUS was used to gate off the OMAP2+ Kconfig
Keystone2 family devices lost this config option.

Move this option out of mach-omap2 Kconfig to a spot accessible by both
families. We picked arch/arm/Kconfig over the TI specific board/ti/
location as this option is not specific to our boards but rather our
architecture.

Plus at some point this option can be changed to just
SECURE_DEVICE, as having secure parts is not exclusive to TI and
so other vendors can interpret this option as needed by their device
configurations.
